Safety Precautions
Radio Frequency Radiation Hazard
This symbol indicates a risk of personal injury due to radio frequency exposure. The radio
equipment described in this guide uses radio frequency transmitters. Do not allow people to
come in close proximity to the front of the antenna while the transmitter is operating. The
antenna will be professional installed on fixed-mounted outdoor permanent structures to provide
separation from any other antenna and all persons.
WARNING: RF Energy Exposure Limits and Applicable Rules 1 for 6-38 GHz. It is recommended that the radio
equipment operator refer to the RF exposure rules and precaution for each frequency band and other applicable
rules and precautions with respect to transmitters, facilities, and operations that may affect the environment due
to RF emissions for each radio equipment deployment site.
Worst case RF Energy Radiation occurs when maximum transmitter power and maximum antenna
gain are used. The referenced transmitter power is +30 dBm (1 Watt) and the antenna gain is 50
dBi (12 Ft diameter parabolic antenna plus any radiating structure). The resulting EIRP is +80 dBm
or +50 dBW. The safe separation distance is at least 17 meters between the antenna and persons when normally
operated in occupational or controlled conditions. The safe separation distance for all persons and passer-bys,
from the antenna is at least 38 meters in general population RF exposure conditions. Refer to applicable rules1
for lesser EIRP exposures.

RF-11000E Operations Manual
Chapter 1. Overview — 1
RF-11000E Microwave RF Repeater
Functional Description
1. The RF-11000E assembly is an RF through repeater designed for remote locations. Little
alignment is required, and the use of highly reliable components and minimum active circuitry
eliminates most subsequent maintenance. The repeater assembly consists of an equipment
mounting panel, contained in an aluminum, weatherproof, enclosure. If desired, the complete
assembly may be wall-mounted. In most applications however, the complete assembly is
pipe-frame or tower-mounted. Front views of the repeater are shown in Figures 1 and 2. Bottom
detail is shown in Figure 3. Typical Rack Mount Option is shown in Figure 4.
2. In addition to the RF-11000E repeater assembly, Peninsula Engineering Solutions offers
accessory equipment consisting of static desiccator and pressure test assemblies, antennas and
mounting hardware, waveguide, and complete site power supply systems. The recommended
antennas are solid or high performance types chosen per application.
Basic Repeater
3. The RF-11000E duplex repeater uses internally redundant amplifiers for transmission in each of
two directions. Each amplifier is powered by two separate battery supplies for added reliability.
Bandpass filters and circulators, which form a duplexer network, direct the received signals to the
amplifiers, and then combine the amplifier outputs with the received signals to a common
antenna port for transmission in each direction (see Figures 9 to 22). The repeater supports
frequency division duplex, FDD, radio link systems where separate frequencies are used in each
direction.
4. The received signal from "A" antenna, identified as frequency "f1", enters the repeater panel via
the cabinet mounted WR90, cover flange and is then fed to a RX-TX branching circulator. Then
from the channel branching circulator, the f1 signal is passed to the f1 receive bandpass filter.
The bandpass filter passes the f1 signal to a terminated coaxial circulator and (optional) f1
receive pad and then to amplifier A1. The amplified signal passes through the (optional) f1
transmit pad. From the transmit pad the f1 signal then passes through a terminated coaxial
circulator and the f1 transmit bandpass filter to the channel branching circulator and then to the
RX-TX branching circulator. From there to cabinet mounted WR90, cover flange for connection to
the "B" antenna.
5. In the other direction, the receive signal from "B" antenna, identified as frequency "f2", enters the
repeater panel via the cabinet mounted CPR90G, flange and is then fed to a RX-TX branching
circulator. Then from the channel branching circulator, the f2 signal is passed to the f2 receive
bandpass filter. The bandpass filter passes the f2 signal to a terminated coaxial circulator and
(optional) f2 receive pad and then to amplifier 2. The amplified signal passes to (optional) f2
transmit pad. From the transmit pad the f2 signal then passes through a terminated coaxial
circulator and the f2 transmit bandpass filter to the transmit channel branching circulator and then
to the RX-TX branching circulator and the cabinet mounted CPR90G, flange for connection to "A"
antenna.
6. Receive pads RX f1 and RX f2 reduce the repeater receive signals to approximate the
recommended input level. The transmit pads designated TX f1 and TX f2 reduce the output
signal levels of the repeater for regulatory compliance and to prevent overloading of the terminal
receiver on a short hop. Pads are mounted on input and output of amplifiers. Nominal input and
output power level for various repeater channel configuration are listed at in Technical Summary
following this section.
7. Delay Equalizers are added to correct for the slope and parabolic group delay introduced by the
bandpass filters and branching networks. Equalized repeaters are recommended for high
capacity systems, tandem repeater applications and multiple carrier 1+1, 2+0, 3+0, 4+0
configurations.

RF-11000E Operations Manual
RF-11000E Microwave RF Repeater
Amplifiers
8. In digital radio applications, in order to maintain linearity over the entire signaling envelope, the
amplifiers operate at a reduced average power level to meet the output power level requirement
as shown in Technical Summary. Each amplifier is mounted on the front of the panel to allow
easy AGC/ALC and linear gain adjustments. It also provides easy amplifier replacement in the
field. Necessary information for ordering spare or replacement amplifiers is provided later in
Chapter 1, Ordering Information.
Directional Couplers
9. Directional couplers, built into the amplifiers, provide signal monitor points, “RF MON”. These
allow in-service measurement of transmit output power. The monitor points are calibrated for
calculating the actual RF output power at the amplifier output and at the antenna port flange.
When measuring transmit power, the power meter reading obtained, plus the loss (in dB) marked
at the amplifier monitor point, minus the branching loss (in dB) marked on the panel, equals
actual antenna port transmit output power.

AGC/ALC Adjustment
10. There is a field-adjustable potentiometer on each amplifier. The amplifier output power set level is
adjusted by AGC/ALC potentiometer. This is a multi-turn potentiometer.
Linear Gain Adjustment
11. On each amplifier, there is a second field-adjustable potentiometer for linear gain adjustment to
limit its maximum gain. Gain adjustment is typically only used in cases where antenna isolation is
inadequate to support the required C/E at maximum gain. In the majority of cases, the AGC/ALC
automatic adjustments are all that is needed.
Power Supply
12. The only active element in each frequency channel of the RF-11000E assembly is the amplifier
which operates from a +8.5 VDC source. Two DC supplies of +24 VDC are brought into the
repeater enclosure. They are converted to +8.5 VDC by two DC-DC converters and power the
amplifiers in redundant-protecting mode. Current requirements, at +24 VDC, are 2.7 Amperes
maximum per duplex system and 5.4 Amperes maximum per duplex, frequency diversity system.
Solar Rated power consumption accounts for lower current demands under normal conditions.
The repeater assembly may be powered from alternative energy source such as solar panels,
wind turbines, thermal electric generators, fuel cells, primary cells only, or from an AC/DC supply
with standby battery (shown in Figures 23 and 24).
13. Storage batteries and solar photovoltaic modules are selected on the basis of the insolation and
temperature range at the site. The batteries are engineered to provide the required reserve
capacity across the temperature range and during periods when the output from the PV array is
low or not available. Controllers are used with the photovoltaic modules to efficiently charge the
batteries without overcharging. Peninsula Engineering Solutions can determine the PV array and
battery capacity. The location of the site should be specified when requesting assistance.
14. In areas where commercial power is available, an AC power supply can be provided. Although
one AC power supply will provide ample current to power all amplifiers, dual AC power supplies
are recommended for higher reliability. The dual AC power supply system also contains two
RF-11000E Operations Manual
Chapter 1. Overview — 3
RF-11000E Microwave RF Repeater
rectifier/chargers and two sets of standby battery to provide power during AC power failures.
Each battery is float charged while the power supply is on and has 100 Amp-hours as standard
capacity. Additional batteries can be purchased if needed.
15. In locations where commercial power is not available and solar panel charging is impractical,
then alternative power sources such as thermal-electric generator, TEG, fuel cell, or motor
generator are available. Power sources may be used in combination to create hybrid power
solutions capable of operating in very demanding applications. Primary cell batteries capable of
powering an RF-11000E repeater in excess of a year may be used. In such applications, the
battery installation should be given an environmental shelter according to the manufactures’
recommendations. Contact Peninsula Engineering Solutions for assistance in designing the best
power supply system.
Alarms
16. The RF-11000E repeater can be provided with an optional alarm system (RMAS) to remotely
monitor the repeater site. Conditions that are typically monitored are listed below:
Standard Trip Points:
Standard Telemetry:
c) A and B Battery Major Alarm
d) East and West RF Output Low
e) Amplifier Alarm
f) Cabinet Door Open
g) Feedline pressure low
h) Uncommitted Points
a) A Battery Voltage
b) B Battery Voltage
c) Battery Temperature
d) Auxiliary Voltage
17. The standard alarms are typically relayed back to the terminal site through the use of a low rate
telemetry signal directly modulated on the microwave carrier in a non-interfering fashion. Alarms
are visually displayed on the standard terminal receiver unit. Alarm contact closure outputs are
available for input to standard microwave supervisory systems.
18. Alternative alarm equipment is available that transmits alarm data subset via UHF radio telemetry
links operating in parallel to the microwave hop. This type of alarm equipment is used when
access to the terminal radio AGC is not available or compatible.
19. Alarm closures can be converted to SNMP reporting over IP networks using Peninsula’s
SNMP-SL10 unit.

Transmit power set point is reduced as the modulation becomes more complex. This power
“backoff” provides adequate linearity as required by the system performance objectives.
The ALC adjustment on each amplifier is used to set the output power level. To calculate the
repeater’s output power at the antenna port flange, take the amplifier power output without
backoff, reduce that level by the backoff listed in this table, then subtract the transmit branch loss
for the specific configuration from Tables 2 or 3.
For Example: Level 2 Amplifier Power Output = +32 dBm without backoff reduction,
Modulation is 256QAM, therefore backoff = 13.0 dB, RF-11000E-041 Tx Branch Loss = 2.8 dB,.
Output power at antenna port flange = +32.0 – 13.0 – 2.8 = +16.2 dBm.
12
Modulations listed are the most popular types. List is not exclusive. If a modulation is not listed,
contact the company for specific details.

RF-11000E Microwave RF Repeater
Ordering Information
The RF-11000E RF Repeater Assembly is ordered by specifying the system model number
RF-11000E-XXX (Table 4). Attenuators are provisioned by specifying their part numbers.
Transmission engineering must be completed before ordering because the necessary attenuator
values are determined from the path calculations. Part numbers are listed in Table 5.
When doing the initial system layout of a radio link which includes an RF-11000E Microwave RF
Repeater Assembly, several factors must be considered prior to ordering, to ensure correct antenna
connections and proper installation. Consider the following topics before ordering the RF-11000E
Microwave RF Repeater:
Repeater Transmit and Receive Frequencies
Repeater frequencies are coordinated with the adjacent terminal radios. See the block diagrams
for more detail. Orders cannot be accepted without firm frequencies. Frequency assignment
locations within the repeater can optimize the repeater antenna ports relative to the site antenna
feedline routing. Peninsula Engineering can assist in determining the frequencies and
assignments.
Terminal Radio Modulation, Traffic Capacity, Bandwidth, and Repeater Transmit Power Level
Repeater transmit power levels are set based on the modulation and traffic capacity of the
adjacent terminal radios. Please include the modulation and traffic capacity details with the
purchase order. Peninsula Engineering will determine the proper transmit power level.
Modulations and traffic capacity beyond those listed in this manual may be possible to support,
contact Peninsula Engineering Solutions for more details.
Electric Power System
The repeater site power system should be detailed during the system design phase. Peninsula
Engineering Solutions can provide this design service and the power equipment. Power systems
may include: Solar, Wind, AC, TEG, Motor Generator, Fuel Cell, or other power sources. All
power systems include a battery plant and associated charge control equipment. Battery capacity
must be adequate for the load, location, and power source.
Antennas
The types and sizes of antennas required to meet the system requirements. Transmission
engineering can determine the antenna details. Transmission engineering and antennas are
available from Peninsula Engineering Solutions.
Feedlines
Type and length required for antenna connections (including jumper assemblies); note that
waveguide is available from Peninsula Engineering Solutions.
Mounting
Special requirements for the repeater and antennas specific to the intended tower or supporting
structure. The repeater normally mounts outdoors in its all-weather enclosure. Peninsula
Engineering Solutions can provide construction engineering support.
Alarm System
The Repeater Monitor and Alarm System equipment is optional. Please refer to Table 9 for
ordering details or refer to the alarm equipment manuals.
When ordering, specify a shipping destination and a billing address. Peninsula Engineering Solutions
returns an order acknowledgment with the scheduled shipping date. Each shipment includes an
equipment list showing the equipment ordered and shipped, including details about system and
equipment options.

Chapter 2. Installation Instructions — 39
RF-11000E Microwave RF Repeater
Pre-Installation Site Review
Each site should be thoroughly reviewed before any equipment is mounted. Site review should
include, but not necessarily be limited to, the following factors:
Weather
Determine whether environmental conditions necessitate special shielding of the repeater or
other equipment.
Security
Determine whether some type of barrier is needed to protect equipment and if a security light is
required.
Aviation
Review tower heights and obstruction lighting requirements as specified by the national aviation
authority, e.g. US-FAA, US Federal Aviation Authority or Transport Canada. Normally towers
200 Ft AGL and taller require obstruction lighting. Towers closer to airports have additional
lighting and marking requirements. File NOTAMS as required during construction.
Optional Site Equipment
Determine whether additional site equipment, such as a convenience power outlet, pump,
generator, or light is required, and, if so, where equipment is to be located and whether special
enclosures for any equipment is required.
Wiring and Wiring Access
Determine any special wiring requirements.
Cabinet Access
Determine whether there is enough room for the repeater door to open, once mounted.
The RF-11000E assembly can be mounted on a steel tower, on a steel pipe or square-rail frame, or
on a wall. The length of all power leads should be limited and the wire size adequate to minimize the
voltage drop. The repeater assembly, battery boxes, solar panels, and antennas should all be
mounted before any wiring is done. Mounting-hole dimensions for the repeater enclosure are shown
in Figure 26.
Prior to cutting to length and connecting the waveguide feedlines, verify which repeater’s receive
frequency associates with each antenna port and associated terminal radio site. The repeater
receiving frequencies and transmitting frequencies are marked on the top of repeater, near
waveguide antenna ports. Coordinate site names are marked in the same location, when known.
The waveguide feedlines are terminated in CPR90G Flange. The repeater is not designed for
pressurization. Use external pressure windows at the CPR90G Flanges if the feedlines are to be
pressured or dehydrated.
CAUTION: In an extremely hot and sunny environment, such as a desert, shading from direct
sunlight may be necessary to prevent the repeater and associated equipment from
overheating. Locating battery enclosures in the shade of the solar array is
recommended.

Chapter 3. Mounting the Antennas
Mount Antennas
Mount all antennas, antenna feedlines, grounding, dehydration, and lightning protection. Test the
completed antenna system installation prior to repeater equipment installation. Follow details of the
site plan if available.
Antenna Types
Microwave RF repeaters can use any one of four typical parabolic antenna types:

Standard performance, single or dual polarized.
Improved performance, FCC Category A, single, or dual polarized (Deep Dish, PAR, PAD).
High Performance, single or dual polarized.
Ultra-High Performance, single or dual polarized.
NOTE: Antenna type is normally determined by the system requirements, especially the repeater site
antenna isolation objective for the radio system modulation. More complex modulations
require greater Carrier to Echo, C/E and hence, greater isolation. Repeater system path
calculations, path data sheet, are used to determine the antenna size and type.
Antenna Mounting Location and Precaution Guidance
Locate antennas such that RF energy exposure as described in US FCC OET Bulletin
65 is met. Normally antennas are located where the main beam is above the height of
nearby persons and objects. Since the intent is to have clear line-of-sight path to the
distant end, mounting locations meeting clear LOS will normally meet RF energy
exposure limits.
Appropriate warning signs must be properly placed and posted at the equipment site and access
entries. See “Radio Frequency Radiation Hazard” section on page iii.
Mount the antennas securely on adequate mounting structures. Mounting structures must meet
strength, twist, and sway requirements for 11 GHz antenna systems. Provide means for alignment
adjustments.
Antenna Alignment
Coarse Alignment
To initially orient the antennas:
1. Align the “bore-sight” of the antenna to the calculated azimuth as shown in the site layout or path
calculations. Be sure to account for geomagnetic declination when using a magnetic compass.
Azimuths are normally shown as True North. Geomagnetic declination varies by site location and
typically drifts every year as the location of the earth’s magnetic pole moves.
2. Adjust the elevation to match the calculated elevation angle.
Fine Alignment using test radios
3. Peninsula Engineering recommends using test radios to do the alignment over the hop. This is
much easier than attempting to use the limited repeater level indications or measurements. The
test radios also provide a talk channel to allow the alignment teams to rapidly communicate with
each other.
RF-11000E Operations Manual
Chapter 3. Mounting the Antennas — 43
RF-11000E Microwave RF Repeater
4. Identify the polarization determined for the hop. Consult the antenna manufacturer’s
documentation on identifying the vertical or horizontal antenna port on dual polarized antennas or
how the feed assembly is installed and oriented in single (plane) polarized antennas. Failure to
properly identify polarizations will result in antenna misalignment and violate the station license.
5. Attach the test radios to the proper antenna waveguide port at each end of the hop.
6. Consult the path calculations, PDS, for the net path loss calculated between the antennas.
Correct for feedline losses when connected directly to the antenna waveguide ports.
7. Begin aligning the antennas. It should be possible to meet the calculated net path loss ± 1 dB.
8. Record the alignment and loss details. Provide the records to the end customer or controlling
authority.
Alternative Fine Alignment using repeater power measurements
9. This method requires the RF-11000E repeater to be installed, connected to the antenna
feedlines, and powered up. See Chapter 4 for repeater installation details.
10. Before antenna orientation begins, the amplifiers must be operating in their full gain mode (out of
AGC/ALC range). The setting of the AGC/ALC along with a high input level (greater than [desired
output power level in dBm - max. linear gain in dB] ) may cause the normal action of the
AGC/ALC circuit to mask changes in power due to azimuth and elevation sweeping of the
antennas. The output power of an amplifier will increase in level as the input level is increased to
the point where the AGC/ALC has been set (e.g. +18 dBm). Further increases in input level will
be absorbed in the AGC/ALC circuit. Use the amplifier power monitor point as a signal strength
indicator. The input level can be reduced temporarily by inserting a fixed or variable attenuator
pad ahead of the amplifier. The attenuation required will range from 0 to 30 dB depending on
desired power and input signal level. Remove the input semi-rigid coax cable and place the
attenuator in series with the coax or use flexible coax as required for fit. Reduce the input level
until the output power drops below the desired power level. If during antenna orientation, the
power rises to the desired power level, reduce the input level again and then continue with
antenna orientation.
11. Alternatively, the amplifier's maximum gain can be reduced such that the system is out of
AGC/ALC for antenna alignment. Gain adjustment is provided by a potentiometer just below the
AGC/ALC adjustment. Be sure to return the potentiometers to their normal positions after
antennas are aligned. (Usually at the maximum linear position.)
12. Connect the power meter or spectrum analyzer to the f1 amplifier, A1, RF MON port. With a
signal transmitted from the A terminal, position the antenna A for a maximum power reading on
the meter or analyzer. After antenna A is aligned, remove any temporarily installed input
attenuators. Re-set the power level with the AGC/ALC adjustment if needed. The AGC/ALC
adjustment is located near the output end of each amplifier, see Figures 7 and 8. Use a screw
driver or tuning tool to adjust the AGC/ALC potentiometer CW to reduce the power setting or
CCW to increase the AGC/ALC set point. Log the power reading to fulfill FCC requirements.
Remove the meter from the f1 Amplifier RF MON to the f2 Amplifier RF MON.
13. With a signal transmitted from the B terminal, position the antenna B for a maximum power
reading on the meter or analyzer. After antenna B is aligned, remove any temporarily installed
input attenuators. Set the power level with the AGC/ALC adjustment if needed. Log the power
reading to fulfill FCC requirements. Measure and log the power at any additional amplifier (RF
MON) directional couplers so equipped (f3, f4...). Remove the meter.
14. After the antenna orientation has been completed at both terminals and the repeater, AGC/RSL
readings should be taken at the end terminals and logged for reference. Provide the records to
the end customer or controlling authority.
44 — Chapter 3. Mounting the Antennas
RF-11000E Operations Manual
RF-11000E Microwave RF Repeater
Antenna Feedlines
The RF-11000E repeater uses waveguide feedlines. For the 10.7 ~ 11.7 GHz band, typical feedlines
are elliptical waveguide such as EWP90 and EP105. The RF-11000E has CPR90 Flanges at the top
antenna ports. The equipment end of the waveguide feedline must have a matching CPR90 contact
flange installed. The antenna end of the waveguide feedline must have a connector flange that
matches the installed antenna’s flange. Typical antenna flanges in this band are CPR90G and
PDR100.
Waveguide feedlines require dehydration equipment to maintain a dry atmosphere within the
waveguide to prevent moisture accumulation which leads to corrosion and higher transmission
losses. RF repeater applications typically have shorter waveguide runs and thus, a smaller volume of
air within the waveguide. Static desiccators are ideal in this situation. A static desiccator will passively
dry air passed through its silica gel as daily temperature and pressure changes gently move the air.
These units do not require any power to operate and provide 1 to 2 years field lifetime before
requiring replacement or service. Peninsula Engineering recommends mounting static desiccators
inside the repeater enclosure to protect against aging from direct sunlight. See manufacturer’s
specifications and recommendations when considering static desiccators.
Dry Nitrogen is another method to keep waveguides dry without using power. Nitrogen supplied in
high pressure bottles is reduced in pressure with a regulator and then passed to a gas pressurization
manifold with distribution to the feedlines. Nitrogen replaces the air within the waveguide (purged at
installation) and the positive pressure helps force moisture away from entering the waveguide. To
warn of an empty gas bottle, the optional RMAS alarm equipment can be optionally provisioned with
a low pressure switch that can be added to the pressurization manifold. When gas pressure drops
below 1 psi, a warning alarm is issued.
RF-11000E repeater configurations require one feedline per equipment antenna port, typically:
⇒
⇒
⇒
⇒
⇒
One for the primary West antenna
One for the primary East antenna
One for the diversity West antenna, if applicable
One for the diversity East antenna, if applicable
One per direction and polarization in Y-Junction applications
The allowable transmission loss for antenna feedlines is specified in the site plan or path calculation,
path data sheet documentation for the project. Do not install feedlines different than as specified.
Feedline Installation
To install waveguide feedlines:
1. Install the top connector (goes to the antenna). Use a flaring tool for best attachment and
impedance, Z0, match.
2. Raise the cable up the tower to the antenna. Use a hoisting grip.
3. Position the waveguide and secure the top section. Carefully bend the elliptical waveguide to
align with the antenna flange. Be mindful of the bend and twist specified limits of the waveguide.
If necessary, use rigid twist and bend sections to aid in alignment.
4. Connect the waveguide to the antenna.
5. Securely install the feedline so that it reaches to the installation site of the RF-11000E, with
enough room to connect to the repeater.
6. Secure the cable to the tower or structure about every 3 feet or 0.9 meters.
7. Carefully measure and cut to length the waveguide.
8. Terminate the waveguide with a CPR90 flange connector.
RF-11000E Operations Manual
Chapter 3. Mounting the Antennas — 45
RF-11000E Microwave RF Repeater
9. Position the waveguide and secure the bottom section. Carefully bend the elliptical waveguide to
align with the repeater equipment top flange. Be mindful of the bend and twist limits of the
waveguide. If necessary, use rigid twist and bend sections to aid in alignment.
10. Flexible twist-flex waveguide jumper may be used at either end if needed. These jumpers have
higher loss and shorter life than rigid twist and bend sections.
11. Trial fit the bottom connector to the repeater equipment top antenna port flange or intended
flange location. Do not permanently install until the feedlines are sweep tested.
12. Install waveguide grounding kits. Normally the waveguide is grounded at the top and bottom and
at the shelter entrance. Follow grounding practices prescribed by the controlling authority.
13. Pressure windows are recommended at the repeater equipment top antenna ports.
14. Install dehydration equipment.
Lightning Protection
Peninsula Engineering Solutions strongly recommends installing protection on the tower, structure
and on all feedlines to the repeater. A direct lightning strike can damage any electronic equipment.
Damage resulting from a lightning strike is not covered under the equipment warranty, whether or not
lightning protection is used. However, using lightning protection can minimize the risk of damaging a
repeater, and of losing equipment operation during thunderstorms.
Elliptical waveguides are protected by installing grounding kits, typically at the top, bottom and at
shelter entrance.
Lightning rods mounted adequately above the highest antenna or power equipment provide a
diversion path for lightning strikes. Multiple lightning rods may be required.
Towers, shelters and all equipment must be bonded and grounded to minimize any potential
differences that can occur due to a lightning strike.
Follow grounding practices prescribed by the controlling authority.
Sweeping the Antenna Feedlines
Sweep testing of the installed feedlines and antennas is recommended. Sweep testing is the same as
performed at a terminal radio site. Measurement of impedance match and insertion loss over the
operating frequencies insures that the antenna system is installed properly and is ready to perform.
Most microwave operating companies have developed their own performance standards for antenna
systems. Use such standards if available. If company standards are not available, consider the
following:

Sweep frequency range: 10,700 ~ 11,700 MHz or across all assigned channel bandwidth.

Impedance Match: 20 ~ 26 dB Return Loss or 1.22:1 ~ 1.11:1 VSWR across the channel
bandwidth. If tunable connectors are provisioned, adjust the tuning screws to optimize the
match.

Insertion Loss: Per calculated. Typical waveguide loss 13 is 3.0 dB/100 Ft or 10.0 dB/100 m.

Distance to Fault, DTF: Measure Return Loss of the antenna system components and isolate
troubles. Use DTF function of Anritsu Site Master™ test equipment.
If the impedance match or insertion loss is not met, troubleshoot the feedlines and antennas for the
source of the problem. Use the “Distance to Fault” function to assist in localizing the trouble. Correct
as required before proceeding.

Measuring Antenna Isolation – Decoupling
System path calculations by Peninsula Engineering will determine the recommended antenna size
and type plus the feed-horn to feed-horn separation and polarization loss. Our experience has been
that if the recommendations are followed, antenna isolation will be met with some margin and direct
measurement of antenna isolation is not required.
Should there be reason to determine the antenna isolation, proceed with this section.
Measure the actual isolation between the antennas, to ensure that the antennas are sufficiently
isolated from each other and that the system Carrier-to-Echo Ratio, C/E, objective is met.
CAUTION: This is an important consideration in all on-frequency repeater installations.
If the isolation is not sufficient, the repeater might oscillate in the extreme, or the repeater system
might have inadequate carrier-to-echo ratio, C/E, margin, which can lead to bit errors in digital radio
systems.
In some cases, it may be necessary to reduce the maximum repeater gain by adjusting the amplifier’s
GAIN setting potentiometer and thus obtaining the required C/E. Normally isolation is met and
amplifier GAIN setting allows for maximum ALC managed gain.
C/E = [Isolation, dB] – [Repeater Operating or Maximum Gain, dB]
Example 1: Isolation = 110 dB, Operating Gain (ALC reduced) = 45 dB
C/E = 110 – 45 = 65 dB
Example 2: Isolation = 110 dB, Maximum Gain (full gain) = 60 dB
C/E = 110 – 60 = 50 dB
Table 10 lists the C/E and isolation objectives for various radio modulation types.
Isolation is controlled by the antenna Front-to-Back, F/B, ratio, sidelobe suppression, separation
distance between feed-horns, angle between the antenna centerlines, polarization, and feedline
losses.
Measuring antenna isolation requires a signal generator and a spectrum analyzer. The generator
transmits a signal from one antenna, and the spectrum analyzer measures the same signal as the
second antenna receives it. Figure 27 shows the equipment set-up. Losses between 80 and 120 dB
are measured. Be sure the test equipment is capable of adequately measuring such high loss values.

The leakage signal between antennas acts as a co-channel, like interferer. The time offset or echo
delay is typically close to 200 nanoseconds with 50 feet, 15 meters, of combined feedlines. In
medium to high capacity digital radio systems, this time offset results in intersymbol interference.
Adaptive equalizers can reduce the effects of the echo signal. The objective C/E values listed
assume minimal correction from adaptive equalizers or forward error correction. As a result,
performance may be better than predicted depending on the microwave radio equipment capabilities.

For < -1 dB system gain at 10-6 BER or BER < 10-12 at normal RSL.

Isolation objective assumes a maximum repeater net gain of 60 dB. Isolation required for a specific
C/E decreases dB-for-dB as the maximum gain decreases.

Figure 27 Antenna Isolation Measurement - Equipment Configuration
NOTE: In all cases, measure antenna isolation with all feedlines, jumpers, cables, and connectors in
place. Record all measurements for future reference.
The equation for antenna isolation measurement is:
ISO = PGEN – (LC-GEN + LC-SA) - PSA
Where:
ISO
= Isolation in dB between the antennas.
PGEN
= Output level of the signal generator (dBm).
LC-GEN = Loss of the signal generator cable, CASG (dB).
LC-SA
= Loss of the spectrum analyzer cable, CASA (dB).
PSA
= Power indicated on the spectrum analyzer (dBm).
For example:
PGEN
= 10 dBm
LC-GEN = 1.0 dB
LC-SA
= 1.0 dB
PSA
= -92 dBm
ISO
= 10 dBm – (1 dB + 1 dB) – (-92 dBm) = 100 dB

Earth, Ground, and Lightning Protection
When grounding the RF-11000E and associated equipment, follow the general guidelines in the
Peninsula Engineering Solutions application note, Installation Standards for Grounding
Requirements.
Installing the input power to the repeater includes installing the standard electrical service grounds.
However, you must also make sure that the repeater enclosure is properly grounded to an earth
ground.
The repeater enclosure includes an external grounding lug on the bottom surface as shown in the
following figure.
Ground Lug
Figure 32 Location of Ground Lug on Repeater Enclosure
1. Connect the screw-compression ground lug to a suitable earth ground—copper ground rod,
copper pipe, ground ring, grounded steel building frame or similar ground point—using 2 to
4 mm, No. 12 to 6 AWG copper wire.
2. Carefully dress the wire along cabinet, and the mounting surface, to the Repeater Grounding
System or the Ground Rod. Recommend using CADWELD® to attach the ground wire to the
rod or ground point.
NOTE:
When dressing the grounding wire, and forming it around corners; avoid making sharp bends
in the wire. Use a generous radius for each wire bend. Sharp bends will cause arc points for
lightning surges and strikes.

Chapter 5. Repeater Tests
Overview
This chapter describes how to test the RF-11000E repeater, to set levels and to verify that it is
operating properly.
Test Equipment Required
Table 8, in Chapter 2, lists test equipment and tools required for testing the RF-11000E repeater.
Equivalent equipment may be substituted.
Applying Power to the Repeater
1. Confirm the repeater is connected to the antenna feedlines, is grounded and that the power
system has been installed and tested. Confirm that all fuses are removed, amplifiers are
unplugged, and RMAS-120 is switched off.
2. Apply primary DC power to Battery A and B terminal blocks TB1 and TB2 on the repeater
main panel.
3. Measure the DC voltage at TB1 and TB2.
Make sure that the voltage is within the operating parameters of the repeater:
•
+24 Volts DC: +19 ~ +30 VDC. Nominal lead acid battery voltage is +25.2 VDC when
fully charged and +27.0 VDC when being charged. Correct as necessary
4. If the optional RMAS-120 alarm equipment is provisioned
and installed, switch ON the alarm transmitter. Press the
yellow LED switch on the lower left to observe all LEDs
illuminate and then report current alarm conditions. To
make testing easier, set the LED Switch jumper to DIS.
This will allow the LEDs to report without pressing the
LED switch.
•
When finished testing, the LED Switch jumper is
returned to the ENB position to conserve power
by only displaying alarm LEDs when the button is
pressed.
5. If the DC power is correct, all the LEDs will light briefly, then these alarm conditions should
be present:

7. Once the Battery A and B alarms clear or TB1 and TB2 are between +19 and +30 VDC and
when measured voltage at TB3 shows +8.5 ~ +9 VDC, then the repeater is powered and
ready for testing.
8. Current Test: Measure the Battery A and B current flowing into TB1 and TB2. Repeaters with
equal numbers of amplifiers will have the two battery inputs close to equal and approximately
half of the total current listed in Table 1. If either battery input has a low or zero current,
check the battery source and distribution system. Record currents for reference.
9. The repeater can operate on a single A or B battery input when needed. Each amplifier can
draw power from both DC/DC converters and thus either battery input. When one battery
source is removed or failed, all the current per Table 1 will flow into the remaining working
battery feed.
Transmit Power Adjustment
At this point, the antennas should be mounted, feeders swept, antennas aligned and isolation
confirmed. The repeater’s power amplifiers have been factory set to the specified output power levels
per the system modulation, when known. Fine adjustments are recommended for best performance.
Greater than recommended power levels can result in amplitude distortion, radio, and line errors
(BER). Less than recommended power levels may have been selected by transmission engineering
(e.g. short hops). Refer to system path calculations and path data sheets for details.
To measure and adjust output power:
1. Calibrate the RF Power Meter for 11 GHz operating frequencies.
2. The far end transmitter operating on repeater frequency F1 must be transmitting at this time.
3. Connect the power meter to the RF MON test port on the side of Amplifier A1 (F1 PA). This is an
SMA-female connector. A right-angle adapter with a between series (e.g. SMA to N) adapter (if
needed) to fit the power meter sensor are needed to access the test port.
4. Measure and record the power meter reading. Typically, this reading will be between -15 and
+15 dBm at RF MON.
5. Add the Cal Loss marked near the RF MON (see Figure 35) to the power meter reading, the
result is the Power Amplifier Output Power.
58 — Chapter 5. Repeater Tests
RF-11000E Operations Manual
RF-11000E Microwave RF Repeater
6. Compare the Power Amplifier Output Power reading to Table 4, using the listing for the radio
modulation type used.
7. Adjust the AGC/ALC potentiometer as required to set the power amplifier output level equal to the
listing in Table 3.
•
Note: Lower levels may have been selected by transmission engineering, please refer to
system path calculations and path data sheets for details.
8. Once the power levels have been set, confirm the RMAS Alarm Transmitter PWR alarm is clear
for each frequency equipped. If the PWR alarm remains active and the transmit power is correct,
then the RMAS Alarm Transmitter alarm point must be adjusted. Please refer to the alarm
equipment documentation for adjustment details. The alarm point is normally 5 dB below normal
operating power level.

9. To determine the Antenna Port Output Power Level, subtract the TX Branch Loss from the Power
Amplifier Output Level. The TX Branch Loss is marked on the repeater panel near the PA.
Include any transmit attenuator pad loss if equipped.

RF-11000E Operations Manual
Chapter 5. Repeater Tests — 59
RF-11000E Microwave RF Repeater
Receive and Transmit Attenuator Pads
Receive, RX, pads attenuate input signals that are greater than can be compensated by the repeater
amplifier’s AGC/ALC circuits. Receive pads are installed on the amplifier input (RF IN) jack.
Transmit, TX, pads attenuate output signals. Transmit signals can also be reduced by adjusting the
AGC/ALC potentiometer. In cases of very short hops, more power reduction may be needed. In these
cases a TX Pad is normally installed. Transmit pads are installed on the amplifier output (RF OUT)
jack.
Pad Installation:
1. If required in the field, the RX/TX attenuator pads should be installed at the RF input or output of
the amplifiers.
2. To install the pad, turn OFF the DC power supply first.
3. Disconnect the input or output semi-rigid coax cable from the amplifier.
4. Connect the SMA male end of the pad to the amplifier’s SMA female input or output; and then
connect input or output cable to the female end of the pad.
5. Check all coaxial connections for tightness (8 in-lbs).
6. Turn ON the DC power supply.
7. Set output power level by adjusting AGC/ALC.
Radio Link Tests
Once the repeater levels have been set and confirmed and antenna alignment is accepted, then,
confirm microwave signals are received at each terminal radio. Observe and record the receiver AGC
or RSL indications for reference.
End to end link tests can now be run. These tests may typically include un-faded BER, radio errors,
system thermal and intermodulation noise. Refer to the radio terminal equipment documentation and
system engineering requirements for the link test plan.
Completion
When setup and tests are complete, set the RMAS Transmit Alarm LED SWITCH jumper to the ENB
position to conserve power by only displaying alarm LEDs when the yellow test button is pressed.
Refer to the RMAS-120 manual for alarm system tests.

Chapter 6. Maintenance and Troubleshooting
The RF-11000E active components are the linear power amplifiers, the DC/DC converters, and the
optional RMAS alarm equipment if equipped. RF repeaters provide long field operating life, often 15
to 20 years. Technologies and traffic needs often drive upgrades or replacement rather than old age.
Routine maintenance checks of the repeater and its supporting equipment will ensure reliable
operation and early detection of problems.
Routine Maintenance
Peninsula Engineering Solutions recommends an annual maintenance schedule for the repeater. The
following is a procedure for routine maintenance:
1. Observe the general condition of the installation site and correct any problems.
2. Verify that the repeater and all associated hardware, including antennas, is securely mounted
and properly in place.
3. Check input electrical wiring and power system for damage and ensure that connections are
tight. Replace any wiring that is suspect.
4. Check any battery terminals for corrosion; clean terminals, if necessary.
5. Check the battery storage capacity condition. Battery impedance testers are recommended.
Battery life expectancy is typically 5 to 10 years in an outdoor environment. Replace any weak
batteries or cells.
6. Clean solar panels and remove obstructions, if applicable. A mild detergent
and water are recommended. Clean solar panels when they are cool, avoid
putting cold water on hot panels, this may cause damage. Dirt, thick dust,
and bird droppings can reduce the output by 30%. Shadows from antennas,
lightning rods, or trees reduce PV output. Life expectancy of PV arrays is
25 years or more. Performance typically declines after 20 years operation.
CAUTION: Follow manufacturer’s instructions when cleaning solar panels. Abrasive or acetonebased solutions can cause damage.
7. Look for lightning strike damage. Solar panels with “holes” punched in
the backing material indicate a lightning strike. Damaged solar panels
or equipment should be replaced.
8. Check antennas and feedlines for damage and ensure that connections
are tight.
9. If the feedlines are pressurized, check that pressure is holding correctly, dehydrators are working
or Nitrogen gas tanks are full.
10. If static desiccators are used to dry the feedlines, check the desiccant color. Blue 16 or Orange is
normal; Pink or Green indicates the desiccant is full of water and needs changing. Static
desiccators should be changed typically, about every 1 to 2 years.
11. If feedline pressure is zero or desiccants are very pink, it’s best to check the feedlines for water.
Drain and dry as required. Inspect for corrosion, correct or replace as required.
12. Check the RMAS alarm transmitter for indications of alarms or trouble.
13. Measure the RF power output level at the RF MON ports. Compare to records.
14. Measure the DC battery load current. Compare to records.
16
Color depends on desiccant material used. Check manufacturer’s specifications. Orange-to-Green
desiccant is EU/CE Compliant.

Chapter 6. Maintenance and Troubleshooting — 61
RF-11000E Microwave RF Repeater
Administrative Requirements
The US-FCC or other local Tele-communications Administrations may require measurement of the
output power of the repeater at installation or when any changes are made which cause the output
power to change. Using the power meter, measure, and log the output power as directed in
Chapter 5.
Troubleshooting
Soft failure of one amplifier will be indicated by a drop of approximately 6 dB in the received signal
level at the terminal in the direction of transmission, which will be indicated on the AGC, RSL meter
on the terminal equipment. Amplifier AGC/ALC may correct for this drop. The failure of one amplifier
will most likely be caused by a failure of DC power to the amplifier. Using the DVM, check for
presence of DC voltage at the amplifier power feed through connections. Another way to check is
insert DVM probes to pins #1 and #2 (Primary DC), then #1 and #3 (Secondary DC) from the back
side of amplifier wire harness as shown in Figures 7 and 8. Pin #1 is Ground. Amplifier DC voltage
should be +8.4 ~ +9.0 V.
If the received signal at the terminals is low but does not indicate a complete failure on one amplifier,
the most likely cause is low voltage from the batteries. Low voltage is an indication of a possible
DC-DC converter failure, battery failure, or a failure of the charging system. In the case of the primary
cell batteries, the batteries are probably reaching the limit of their life. Check the batteries and all
power lead connections. If solar panels are used, be sure they are not obstructed from sunlight and
that the surfaces are clean. If an AC power supply is used, low voltage is probably the result of a
power failure, the duration of which exceeded the reserve power limits of the standby battery. Check
the standby battery in accordance with the instructions given by the manufacturer of the power
supply.
NOTE: Contact the Customer Service Department of Peninsula Engineering Solutions whenever
problems with the unit cannot be resolved.

• Check for alarm conditions and resolve, if necessary.
Battery capacity low⇒
• Batteries may be worn out or undersized, replace and
correct as necessary.
Prolonged storms⇒
• Storms or series of storms can reduce battery
recharging for days. Batteries may be fully discharged
causing the system to fail. Re-evaluate the power
source capacity, increase the PV array or add
secondary power source, increase the battery plant
Ah capacity.
Amplifier power not set⇒
• Set the amplifier output power level per radio
modulation.
Antennas Oriented or
Polarized Incorrectly⇒
• Check antenna orientation and re-align, if necessary.
• Confirm the correct polarizations are used.
Alarm Conditions⇒
• Check for alarm conditions and resolve, if necessary.
Amplifier Failure⇒
• Replace the linear amplifier.
Terminal radio OFF⇒
• Confirm the terminal radio is transmitting.
Improper gain setting⇒
• Check gains and re-set, if necessary.
Input level LOW⇒
• Low input level can be normal, refer to path
calculations for expected levels.
• Confirm the terminal radio is transmitting.
• Confirm frequencies and polarizations match.
Amplifier low gain failure⇒
• Damage to the amplifier can cause low gain which in
turn will reduce the available RF output power.
• Replace the linear amplifier.

PWM: Pulse Width Modulator. PV Controller type that uses a rapid switch to reduce the average
charging current when batteries are fully charged. PV Array Voc should be 1.25 to 2.0 x the
nominal battery voltage. Higher Voc can indicate the array is mis-wired (series instead of
parallel) resulting in less charging current and power.
18
MPPT: Maximum Power Point Tracking. PV controller type includes a DC/DC converter to
“step down” higher voltage PV arrays. Maximum Voc is limited to the maximum rating of the
MPPT controller, typically 150 to 200 VDC.

ii) Amplifier’s RF Detector DC sensitively and output can vary, thus requiring adjustment.
Keeping Spares
Because repeaters are often used to provide critical coverage, customers are advised to follow a
sparing policy. While most telecommunications carriers or system operators have internal policies
relative to equipment sparing, in the event that one does not exist, Peninsula Engineering Solutions
recommends maintaining a minimum of one (1) spare unit for every increment of 10 units or fraction
thereof. This assumes that all spares are immediately available to the technician in need for
installation.
When travel time to a site is long or access is difficult (helicopter, hike or horse), then, more spares
located close to or at the repeater site are recommended. Frequently, organizations will store an
amplifier inside an RF repeater, thus, placing the spare exactly where needed. Amplifiers stored in
sealed, anti-static packaging is recommended for on-site spare inventory.
Each organization should develop a company-specific, equipment-specific policy that meets their
needs, taking into account geographic considerations, and the quantity of repeaters used in the
network.
