equipment damage outlined in the ISM/IM0 at all times.
3.2 Preparations
Prior to starting the operations presented in this method, arrange all
materials and tools at the work location so as to minimize fatigue and
inconvenience.
Inventory the installation components, documentation (installation
manual, floor plans and connectivity chart) and tools you will need.
This method contains tasks that require at least two people to carry them
out.
3.3 Sequence
This is a stand-alone method. It is to be performed after Method 02-
0242, Picocell 1900 General Information." See Figure 1 for sequencing
information.
1. From the System layout and floor plans, locate where the Hybrids are to
be situated. Mount Back boards to support the hybrids if specified and
Mount the Hybrid(s) to the back-board.
2. Use the System layout and floor plans to determine where the antennas
are to be located, and mount the antennas. In the case of Omni antennae
it will be required to mount the antenna after the cable has been run and
terminated.
3. Run the cable between Hybrids, antennas and Picocell transcievers and
Hybrids as specified on the system layout. Tag and designate all cables.
4. Terminate cables with connectors, connect cables to hybrids, antennas
and Picocell 1900 transceivers.
CAUTION Take precautions when working on ladders to
avoid damage or injury from falling or dropped cables
and objects. RF cable is stiff and unwieldy and the
antennas may be mounted in office or high traffic areas.
Carrying out the installation during off hours to
minimize interference with office staff.

4.0 Procedure
4.1 Overview
This Method includes procedures to mount and connect a Picocell 1900
antenna system. Picocell 1900 transceivers may be connected to
antennae directly or combined through hybrids to antennas. Appendix A
provides some reference information for 4 port Hybrids.
Dual 4 Port Hybrid
The Dual 4 port hybrid shown in Figure 1 is a bi-directional RF device
which combines input ports to the output ports and provides isolation
between inputs. The 4 port hybrid Insertion loss is typically 3.5 dB or
less. Connecting one antenna from each transceiver to one 4 port hybrid
input configures each RF channel on all 4 antennae. Cell partitions with
2-4 antennas use a dual 4 port Hybrid. Cell partitions with 5-8 antennas
use a dual 8 port hybrid.

Dual 8 port Hybrid
The dual 8 port hybrid shown in Figure 2 is a multiple hybrid device,
which internally configures 4 port hybrids to connect 4 input ports to 4
output ports with isolation between input ports. Insertion loss on the 8
port hybrid is typically 7.2 dB or less. The two antennae from each
transceiver connect to an input on each 8 port hybrid and so configures
each RF channel on all antennae connected to the hybrid outputs. Low-
loss coaxial cables connect between the antennae, hybrids and
transcievers.

5.0 Mounting the Hybrid(s)
Hybrids may be mounted on bare wall surfaces; transceivers must
follow mounting guidlines listed in IM 02-0245. Typical back board
mounting is illustrated in Figures 5 and 6. Hybrids are passive devices
and may be mounted in enclosed spaces; leave room for cabling and test
access. Ceiling mounting of hybrids should include custom brackets
with nut and bolt fasteners with IDS clips (see IM 02-0245) to support
the hybrid and cables. Supporting hybrids on ceilings with common dry
wall anchors is not recommended. The hybrid requires a mounting kit
consisting of:
- 2.5" x # 10 wood screws
- washers 1/2" outside diameter
- a hole drilling template
Figure 3 – Dual 8 Port Hybrid (CPC A0737243))
Note: The Hybrid(s) should be mounted to permit the RF cables to enter
and leave with out excessive bending and stress on connectors.

6.0 Picocell 1900 Antennas
Two antennas types are supported in this document which may be
provided in the system design. the The directional antenna must be
mounted vertically on the wall and may swivel over a +/- 30 degree
range, with the front of the antenna facing in the direction of RF
propogation.
The Omni antenna is only mounted on ceilings and weighs .52 lb (.23kg)
and does not require any extra support. The wall mount Directional
antenna weighs .5 lb as well. Refer to the floor plan for tolerances on
deviating from the ideal position should it not be possible to mount in
the specified position due to obstructions.

7.0 Cable Types and Connectors
Andrew cables and connectors are recommended for use throughout the
Picocell 1900 antenna system. One exception is the Huber-Suhner
Jumper at the Picocell 1900 transceiver. The tables below lists
recommended connector and cable types. The Andrew Corporation
connector catalog numbers, Nortel CPC part number, manufacturer and
insertion loss is listed below. Circumstances may result in equivalent
cable types being specified or sourced from other manufacturers. Use
the original Equipment Manufacturer’s (OEM) instructions supplied
with the connectors for assembly.
The N(m) to TNC(m) jumper connects the main transmission line to the
Picocell 1900 transceiver which requires a flexible cable for entry.

Procedure 4 – Placement of RF Cable
1. Inspect the cable for possible damage and verify the cable type being
placed with the system layout. Also verify that the cable type being used
meets the requirements for insertion loss as specified in the layout. See
Table 4. Maximum lengths and insertion Losses should be detailed on
the System layout or floor plan.
Note: Use of a cable reel stand is recommended to minimize stress when
placing the cable. Maintain the cable bending radius outside the
minimum values listed in Table 6 on page 23.
2. Place the cable as directed in the System Layout.
Note: When placing the RF cable equipped with connectors, use
protective plugs to prevent connector damage. It may be
impossible to run the cable equipped with the connector. In this
case run the cable to the antenna, leave slack to attach the
connector.
3. Run the cable through the ceiling access hole at the antenna location and
attach the connector to the antenna See "Picocell 1900 Antennas" on
page 18 .
4. Cut the cable to the desired length.
Note: Allow enough length at each end to terminate the connector and
allow the cable to be neatly formed to the Antenna or Hybrid.
Coiling back excess cable is not recommended in order to
minimize cable insertion loss.
5. Attach connectors and label the end of the cable according to the
designation it has been given in the connectivity chart.
6. Attach the connector to the appropriate output port on the Hybrid, and
secure the cable to the mounting wall. The cables should be neatly
formed and secured.
Caution: Do not apply excessive force to cable ties to avoid deforming
or denting the cable shield. Heliax cable damaged with dents or bending
tighter than the minimum bending radius will degrade performance.
Damaged cables should be replaced.

Procedure 5 – Preparing the Heliax cable:
1. Straighten at least 10" of the working end of the cable. Trim 1" off this
end of the cable with the fine tooth hacksaw to provide a fresh working
edge.
Note: Crimping the cable, even slightly, is not acceptable.
2. Use a sharp knife and remove some of the jacket to expose the outer
conductor. See Figure 12 for the amount of jacket to be removed. Avoid
cutting the outer conductor. Remove any burrs on the outside edge of
the outer conductor and clean with solvent.
3. Lightly grease the O ring/gasket and the inner surface of the clamping
nut with silicone. Be careful to apply the silicone only to the desired
areas.
Note: When putting the gasket on, slide the smooth end of the gasket
over the conductor first, being careful not to rip it on the conductor
and ensure it is fitted evenly on the conductor.
4. Screw on the clamping nut: Hand thread the clamping nut onto the outer
conductor, then use a wrench to tighten it into place.
5. Trim the outer conductor so that only the desired amount is left showing
(see Table 5). Use a hacksaw or jewelers saw to cut through the outer
conductor. Use a guide to ensure a straight cut, because it is important
that the cut be parallel to the edge of the clamping nut. Pull the excess
off with a pair of pliers.
6. Cut the inner conductor: Use a hacksaw or jewelers saw to cut the inner
conductor to the desired length (see Table 5). Deburr the cut end with a
file.
Note: Hack-saw blades coated with paint are not to be used to avoid
contaminating the conductor surface with paint impurities.
7. Clean the foam: Use a small brush to clean all the dirt and metallic
particles off the foam. The particles and dirt interfere with the signal
traveling through the cable.
8. Separate foam from the outer conductor: (This is not necessary in the 1/
4" cable/connector assemblies) Gently separate the foam from the outer
conductor. Insert the tip of a knife between the foam and the outer
conductor to a depth of 1/16" and separate them so that the outer
conductor can be flared. Scrape away any foam clinging to the outer
conductor and remove any burrs from the inside edge. Use a small brush
to clean the foam again, if necessary.
9. Flare the outer conductor: The 1/4" cable/connector assemblies, FSJ1-
50A/41PW and ETS1-50T/41PW, require the outer conductor to be
Picocell 1900 Antenna System Installation / 27

Draft
manually flared against the clamping nut. Proceed to Paragraphs 9g and
9h for flaring the 3/8" and 1/2" cable/connector assemblies.
10. Clean the foam off the inner conductor with a knife. Be careful not to
scrape the inner conductor. Use the garnet cloth to remove the adhesive
and to ensure that the surface is clean.
Note: The surface must be residue free, leftover foam can interfere with
setting the pin on the conductor and can reduce conductivity.

Procedure 6 – Flaring 3/8" and 1/2" cable/connector assemblies:
1. The 3/8" and the 1/2" cable/connector assemblies, LDF2-50/L42PW,
ETS2-50T/42SPW, FSJ4-50B/44SEW, LDF4-50A/L44PW, FT4-50T/
L44PW, are designed to be self-flaring:
2. Slip the outer body of the connector over the clamping nut, and tighten
to the appropriate torque using a set of wrenches; see Table 6 for the
appropriate torques. The flaring surface of the outer body will flatten
the outer conductor against the clamping nut.
3. Disassemble the connection and inspect the flare to ensure that there is
good metal to metal contact. If it is not correctly flared, repeat the
procedure.

Procedure 7 – Center Conductor Finishing
1. The connector assembly kit comes with a thin spacing plate which is
used to set the distance between the pin and the outer conductor. It also
shields the dielectric foam from excess heat. Before soldering the pin to
the inner conductor, place the spacing gauge over the inner connector
against the outer conductor/clamping nut.
2. Cut a piece of solder equal in length to the inner hole of the pin and place
in the pin. Place the pin against the end of the inner conductor and apply
the soldering iron at the same time applying slight pressure on the pin.
Figure 20 – Assembling the center pin and center conductor.
3. Heat the pin with the soldering iron; as the pin heats up, it will melt the
solder. The pin will then slide over the inner conductor. Hold for a
second longer to ensure and even flow of solder to avoid a cold solder
joint from occuring.
Note: By first placing solder in the pin a good solder flow is ensured and
solder wetting on the pin surface is minimized as is accidentally
melting the foam dielectric. It is important to push the pin on as
far as it can go. Any excess solder will seep out through the hole
on the side of the pin. This is a good indication that solder flowed
evenly between the pin and center conductor.
4. Remove any excess solder from the center pin with a fine file. Clean
filings off thourghly before final assembly.
Note: Avoid scratching the pin when trimming off the excess solder and ensure
that the pin is aligned with the axis of the cable.

Procedure 8 – Assembling the Connector Body
1. Slide the second O ring onto the groove on the clamping nut and apply
a thin coat of silicone grease. Keep all connector threads free of grease.
Attach the outer body (and flare ring if necessary):
Note: The 1/4" connectors have a flare ring that must be inserted into the
outer body before it is threaded onto the clamping nut.
2. Thread the outer body onto the clamping nut and tighten the connection
with wrenches, see Figure 23. Do not turn the clamping nut to tighten,
turn only the outer body until secure. To ensure a proper connection use
a torque wrench and tighten to the required torque, see Table 6.
3. you will have difficulty putting the outer body on the clamping nut if the
pin is askew. Straighten the pin out slightly and the outer body should
go into place.
4. Check pin alignment to verify the center pin is centered. If it is not,
slide the pin alignment tool over the pin and center it.
5. Check pin depth with the depth gauge to check the setting of the pin.
The gauge shows whether the contact pin is positioned within tolerance.
The gauge is pushed onto the pin assembly and a plunger rises to
indicate if the pin is installed between the upper and lower tolerance
limits. If the pin depth is outside of the tolerances, take off the outer
body and check the pin.
Note: If the pin exceeds the upper tolerance limit, reheat the solder and make sure the
pin is pushed all the way on. If this is not the source of the problem, check the
length of the inner conductor. If the inner conductor is too long, recut the inner
conductor. Re-solder the pin on and repeat procedure 7 and 8.
Note: If the pin is below the lower tolerance level, the length of the inner conductor
has been cut too short. Tightening the clamping nut might correct this situation
if the inner conductor has not been cut too short. If it has been cut too short,
you will have to start the assembly process over again.
6. Slide the black heat-shrink over the connector and cable; use the heat
gun to shrink it in place. Be careful not to melt the heatshrink or the
jacket.

Appendix A - 4 Port Hybrid Insertion Losses
The 4 port hybrid provides isolation between opposite input ports and
between opposite output ports while providing a nominal 3.5 dB
splitting loss between adjacent inputs and outputs. Continuity is
bidirectional between adjacent Input and output ports as shown below.
Unused ports must be terminated in 50 Ohms to maintain hybrid balance
and optimum port return loss.
