Note To User - RF Exposure
MPE Calculation
RF Exposure
Microwave Radio Communications (MRC) provides this warning
for safety purposes with the intent to inform the user of the
potential hazard to RF exposure. The following guidelines for
safe operation were derived from OET bulletin 65, August 1997,
as recommended by the Federal Communications Commission
(FCC).
The 6.4 - 7.125 GHz STRATA transmitter is a mobile transmitter
designed to provide services to broadcast ENG users under
CFR 74 subpart F and 74.601 TV pickup stations. This unit,
operated without an antenna, will not create RF energy
exceeding 1.0 mW/cm2, the FCC limit for exposure. Once
connected to an antenna, the potential for harmful exposure will
be greatly enhanced.
In this situation, a certain distance from the radiator is to be
maintained. Calculations need to be performed to understand
what that safe margin for exposure is. This is known as the
Maximum Permissible Exposure (MPE) limit.
Calculations provided are for common antennas often utilized in
the ENG environment. The following formula used is that
suggested by OET 65.
Calculating MPE
EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P
P = RF power delivered to the antenna in mW
G = Power gain of the antenna in the direction of interest relative
to an isotropic radiator
R = distance to the center of radiation of the antenna in
centimeters
S = MPE in mW/cm² (milliwatts per square centimeters)
Conversions
dBi to numeric gain = Antilog (dBi/10)
Feet to centimeters = Feet * 30.48
Centimeters to Feet = cm * .0328
4 π = 12.57
User Input
RF power delivered to the antenna = Watts
Antenna gain (referenced to isotropic antenna) = dBi
Distance from the center of radiation = Feet
Calculation steps:
1. [P] RF power input. Convert watts to milliwatts = Watts *
1000
2. [G] Antenna gain dBi. Convert to numeric gain = Antilog
(dBi/10)
3. [EIRP] Multiply P * G
4. [R] Convert centimeters to feet = Centimeters * .0328
5. Square R
PG (or EIRP)
S= 4πR2
iiSTRATA TX Operator’s Guide/Tech Ref Manual
6. Multiply R² * 4π
7. [S] Divide (R² * 4π) into EIRP
S = Power Density in milliwatts per square centimeters. Note:
At frequencies above 1500 MHz, S must not be greater than 1

1.9 Supported Repairs
The STRATA TX System, including the TXU, TCU, and optional
ACU, is designed to be compact, rugged and reliable.
Introduction 1-4STRATA TX Operator’s Guide
The TXU and TCU require specialized test equipment to
calibrate amplitude and frequency characteristics after repair. In
addition, sealing the TXU, TCU, or optional ACU enclosures
after repair requires exacting techniques and special fixtures to
ensure weather resistance of the units.
Therefore, there are NO supported field repairs to either the
TXU, TCU, or ACU.
Return the entire unit for factory repair.
If you attempt field repair, you risk damaging your
equipment. If your equipment is under warranty, you may also
affect your warranty coverage.

availability.
The STRATA TX System (typically) consists of the following
components:
TXU The Transmitter Unit (TXU) can be equipped with either an
FM Modulator or COFDM/MPEG module, but not both. A High
Power Unit (HPU) is also contained within the TXU housing to
increase RF power output.
Product Description 2-3STRATA TX Operator’s Guide/Tech Ref Manual
TCU The Transmitter Control Unit (TCU) can be equipped with
either an FM Modulator or COFDM/MPEG module, or both.
ACU The optional AC to DC Power Converter (ACU) provides
+28 VDC power from an AC power source to power one or more
units in a system.
Remote Control Panels Optional Remote Control Panels are
available to allow remote control of the STRATA TX System from
an instrument panel during airborne or mobile operations.
2.2.2 Single Unit Systems
The TXU or TCU may be used independently in single-unit
applications as follows:
• The TXU may be used as a stand-alone transmitter
accepting an IF input.
• The TXU may be used as a stand-alone transmitter
featuring FMT modulation or MPEG and COFDM.
• The TCU may be used as a stand-alone unit used for
FMT modulation or MPEG and COFDM, or both FMT
modulation and MPEG and COFDM.
2.2.3 Multi-Unit Systems
The TXU and TCU can be configured as part of an integrated
system as follows:
• The TCU may contain the FMT modulator and MPEG/
COFDM module supplying an IF signal to a TXU
containing only the RF transmitter.
• The TXU may contain the RF modulator or MPEG/
COFDM module supplying an RF signal directly to the
transmitter antenna.
• The TCU can be separated from the TXU in applications
where the transmitter needs to be placed in another
location.
2.2.4 Remote Control Options
For portable mobile or airborne operations, the STRATA TX
System may be controlled by one of two models of Remote
Control Panels. The Remote Control Panels are mounted in
mobile racks or aircraft instrument panels and are connected via
an RS-232 cable between the Remote Control Panel and the
STRATA TX System.
2.2.5 Antenna and Power Options
The flexible architecture of the STRATA TX System allows a
number of options for both the transmit antenna and the power.
Antenna Options The STRATA TX System is fully compatible
with the MRC family of transmit antennas, including:
• OmniPole omnidirectional
• Megahorn compact horn
• SectorScan flat panel
• MicroScan parabolic
• Ellipse parabolic
Contact your Sales Representative to explore the wide array of
antenna choices available.
CAUTION To prevent damage to your STRATA TX
System, MRC recommends using a +28
VDC power supply. Do not exceed +36
VDC input power or damage will occur.
Product Description 2-4STRATA TX Operator’s Guide/Tech Ref Manual
Power Options The STRATA TX System configurations
operate on +28 VDC power, supplied externally. This DC power
can be supplied by the optional STRATA ACU, or from another
DC power source. Contact your Sales Representative for the
latest details.
Note A TCU and TXU are defined as being “co-located”
when the TXU and TCU are physically separated
by not greater than 6 feet.
If the TXU and TCU are co-located, power must be supplied to
each unit through their individual power connectors from the
same power source. See Figure 2-2. Do not use DC on coax to
power the TXU or TCU when the units are co-located.
Figure 2-2: Powering the TXU and TCU Independently
If your installation calls for separating the TXU and TCU, the
TXU is powered by DC supplied by the TCU or the TCU is
powered by DC supplied by the TXU. The DC power is
superimposed on the coaxial cable connected between the units.
See Figure 2-3 and Figure 2-4.
The DC input voltage to the unit co-located with the DC power
supply must be greater than +24 VDC.

DC power superimposed on the coaxial cable between a TCU
and a TXU can be supplied from either the TCU or TXU,
depending upon the location of the DC power supply. Coaxial
cable length/voltage limitations exist when powering from either
the TXU or TCU. These limitations are based on cable size, DC
voltage input, cable resistance, and cable length. A maximum
length of 600 feet (180 meters) between the TXU and TCU is
supported. Contact MRC Technical Support for more information
on cable requirements.
DC power required for a STRATA TX System depends upon the
TX System configuration, i.e., if the TXU or TCU are operated in
a standalone mode, if the TXU and TCU are co-located, or if the
TXU and TCU are mounted in separate locations. See Figure 2-
5 on page 2-6 for the various STRATA TX System configurations
available.
For TX Systems that use DC power sources other than a
STRATA ACU, contact MRC Technical Support for additional
power information.
2.2.6 Mounting and Deployment Options
The STRATA TX offers a number of options for either mobile or
portable applications.
For more details on installation of the STRATA TX in various
applications, see the “Installation” Chapter on page 6-1 (part of
the STRATA TX Technical Reference Manual only).
Mobile Installation For mobile applications such as in a vehicle
or in an aircraft, the STRATA TX System is usually mounted in an
MRC fixed mounting bracket and is installed in a bulkhead or
compartment. The cabling is permanently installed and power
comes from aircraft or vehicle power.
Portable Deployment In portable applications, the STRATA TX
System will be moved from place to place and set up each time.
The TXU and TCU will usually be mounted in a MRC universal
mounting bracket. The bracket is attached to a tripod using a
mounting plate and quick release.
The cabling between the TXU and TCU is typically left in place
and the power, antenna, and audio/video connections are
removed at the end of each deployment.
2.2.7 System Integration
System Communication When the TXU and TCU are
connected, they automatically communicate via signals
superimposed on the coaxial cable between the two units. This
allows them to share information on installed hardware, preset
configurations, current status, and alarms.
System Operation Once the TXU and TCU are connected and
communicating, the units work seamlessly together. System
settings can be selected and modified from the front panel of
either unit, regardless of which unit holds the hardware being
configured.
System Configuration The STRATA TX System offers two
levels of system configuration, designed to match the needs of
different personnel.
For the field operator, the STRATA TX System has up to 9
Presets that can be selected from the front panel. Each Preset
controls key parameters such as modulation, frequency, and
audio and video settings. Additional settings that are front panel-
controlled include band, channel, offset, and filtering.
For the advanced operator and technical staff, the STRATA TX
Configurator software allows complete control of all parameters
in the STRATA TX System. The STRATA TX Configurator
software runs on a Windows-based PC and connects to either
the TXU or the TCU via an RS-232 serial interface cable.
Product Description 2-6STRATA TX Operator’s Guide/Tech Ref Manual
Interfacing a PC to either the TXU or TCU in a connected system
gives you complete control of both units. You can read the
current settings, program new settings, or return the units to their
factory default settings. The STRATA TX Configurator software
automatically detects what hardware is installed in the system
and assigns the appropriate configuration to the correct
hardware, regardless of which unit holds the hardware being
configured.

2.3 System Components
This section will provide more details about each the
components of a STRATA TX System:
•STRATA TXU
• STRATA TCU
•STRATA ACU
• STRATA Remote Control Panels
For details on connections between the STRATA TX System
components, refer to the “Installation” chapter (part of the
STRATA TX Technical Reference Manual only).
2.3.1 STRATA TXU
The TXU (See Figure 2-6) always contains an IF/RF module that
accepts either a 70 MHz COFDM, FMT IF, or external 70 MHz
input signal and up-converts these signals to the required RF
band. The RF frequency synthesizer circuit included in the IF/RF
unit, in conjunction with the command and control power supply
module, provides the means to channelize RF video and audio
signals in the TX System RF band.
The TXU, with either an analog (FMT) or digital (MPEG/COFDM)
module, is integrated in the same housing as the HPU
components. This provides the ability to incorporate high RF
power output (12 watts of saturated RF power) into a single
analog or digital transmitter assembly.
Standard U.S. FCC band plans, as well as customer-created
channel plans, may be customized using the STRATA TX
Configurator software.
Figure 2-6: STRATA TXU
As noted previously, the TXU may also include either an MPEG/
CODFM or FMT module (but not both), in which case the TXU
serves as a stand-alone digital or analog video microwave
transmission system.
2.3.2 STRATA TCU
The TCU (See Figure 2-7 on page 2-8) may contain either
analog or digital or both analog and digital video modulation
modules. Where an application might initially employ only
analog video transmission but expects to migrate to dual,
switchable, analog and digital operation, the TCU may be
upgraded to add the MPEG/COFDM module to add this
capability.
Product Description 2-8STRATA TX Operator’s Guide/Tech Ref Manual
Figure 2-7: STRATA TCU
Where only digital or analog video transmission is desired, the
MPEG/COFDM or FMT modules may be installed in a TXU,
thereby eliminating the need for a TCU. The STRATA TX design
does not permit splitting digital and analog video modulator
modules between a TXU and a TCU.
A TCU may also consist of a stand-alone configuration whereby
either or both MPEG/COFDM and FMT modules may be used
independent of the TXU. This configuration permits use of a TCU
equipped with analog and/or digital video modulation modules
for a variety of signal input and output configurations, including a
digital option using NTSC or PAL composite video input and ASI
(digital) signal output.
2.3.3 STRATA ACU
For fixed or portable deployment applications, the STRATA TX
System may be powered by the optional AC to DC Converter
(ACU). See Figure 2-8.
Figure 2-8: AC to DC Converter
The ACU installs as part of an integrated stack for either tripod or
fixed applications. The ACU may also be used to power the TXU
or TCU only when a TXU and TCU are not co-located. In this
case, the TXU would receive DC power from the TCU or the
TCU would receive DC power from the TXU superimposed on
the coaxial cable connected between the units.
In standalone TXU or TCU operations, the optional ACU may be
used to supply DC power directly to the applicable unit. In the
case where a TXU and a TCU are co-located, it is recommended
that both the TXU and TCU be powered directly from the ACU in
lieu of supplying DC power from the TCU to the TXU or from the
TXU to the TCU via the coaxial cable connected between the
units.
2.3.4 STRATA Remote Control Panels
For mobile or airborne operations, two Remote Control Panel
models are currently available. Contact your Sales
Representative for the latest information.

2.4 TXU and TCU Configurations
TXU Different configurations of the TXU are available,
depending upon if your TX System contains a standalone TXU or
if your TX System contains both a TXU and TCU. The different
configurations are described below.
If your TXU is equipped with either an analog (FMT) module or a
digital (MPEG/COFDM) module and was ordered to operate in a
standalone mode without a TCU, the front panel will contain an
AUDIO connector. See Figure 2-11 on page 2-10.
Product Description 2-10STRATA TX Operator’s Guide/Tech Ref Manual
Figure 2-11: Standalone TXU Configuration
If your TXU was ordered to operate with a TCU, it will not contain
either analog or digital modules and will therefore not contain an
AUDIO connector. The AUDIO connector is replaced by a DC
ON COAX switch. See Figure 2-12.
The DC ON COAX switch allows manual control of DC power to
the TXU from the TCU or from the TCU to the TXU via DC power
superimposed on the coaxial cable connected between the two
units.
The rear of the TXU is identical on both configurations of the
TXU. See Figure 2-12.

When the TCU and TXU are co-located, MRC recommends both
units be powered from the same DC power source.
If your STRATA TX System does not contain a TCU, the DC ON
COAX switch will not be present and an AUDIO connector will
be mounted in place of the switch.
If your STRATA TX System contains both a TXU and a TCU, the
System gives you several ways to control DC power on the
coaxial cable from the TCU to the TXU, depending on the
configurations of your TCU and TXU:
•The DC ON COAX switch on the front panel of the TCU
(See Figure 3-3 on page 3-6) and the DC ON COAX

•The 75 Ohm Coax option on the Command Screen.
Both control methods must be enabled for DC power to be
operational if your TCU and TXU configurations both contain the
DC ON COAX switches. If the DC ON COAX switch is not
present on your TCU, DC power can only be applied using the
75 Ohm Coax option on the command screen. The TXU DC ON
COAX switch must be set to ON in either situation.
TXU SIGNAL INPUT Connector The BNC INPUT connector
provides the IF or video input to the TXU.
TXU AUDIO Connector AUDIO connectors are not contained
on all configurations of the TXU. For configuration differences,
see “TXU and TCU Configurations” Chapter on page 2-9.
If your TXU contains an AUDIO connector, all audio inputs are
applied to the front panel mounted 10-pin connector.
TXU Alphanumeric Display The TXU contains a two-line by
12-character alphanumeric display. The display works in
conjunction with the control switch to allow you to monitor
system status and to control system settings.
TXU XMIT LED When the TXU control switch is pressed for one
second, the transmitter changes from the standby mode to the
transmit mode or changes from the transmit mode to the standby

TXU. This DC power is superimposed on the coaxial cable
between the TCU and the TXU. This DC power option is used
when the TCU and the TXU must be deployed in two separate
locations.
When the TCU and TXU are co-located, MRC recommends both
units be powered from the same DC power source.
If your STRATA TX System does not contain a TXU, the DC ON
COAX switch may not be present. If the switch is present, it
should be set to the OFF position.
If your STRATA TX System contains both a TXU and a TCU, the
System gives you several ways to control DC power on the
coaxial cable between the TCU and the TXU, depending on the
configurations of your TCU and TXU:
•The DC ON COAX switch on the front panel of the TCU
(See Figure 3-3 on page 3-6) and the DC ON COAX
switch on the front panel of the TXU (See Figure 3-1 on
page 3-2).
•The 75 Ohm Coax option on the Command Screen.
Both control methods must be enabled for DC power to be
operational if your TCU and TXU configurations contain the DC
ON COAX switches. If the DC ON COAX switch is not present
on your TCU, DC power can only be applied using the 75 Ohm
Coax option on the command screen. The TXU DC ON COAX
switch must be set to ON in either situation.
TCU Control Switch Routine operating settings are controlled
by the control switch. Turning the control switch right (cw) or left
(ccw) displays status and settings and pressing it in makes
selections, as described below:
Turning the control switch to the right (cw)

on external +28 VDC power sources.
TCU SIGNAL OUT Connector The TNC type SIGNAL OUT
connector provides ASI, CODFM - IF, IF, or IF composite video
output signals, depending upon the options contained in the unit.
In addition, if the TCU is used in conjunction with a separately
located TXU, DC power to or from the TXU is superimposed on
the output signal coaxial cable between the TXU and TCU.
TCU Monitor (MON) Connector If your TCU has COFDM/
MPEG installed, this rear panel output connector can be
configured (when operating in the digital mode) to provide either:
•70 MHz IF
• ASI (output of COFDM modulator, before decoding)
If your TCU is equipped with an analog modulator, this connector
provides only the 70 MHz IF signal output.
TCU SIGNAL IN Connector Video connections are made to
the BNC SIGNAL IN connector. Video input selections are
made by selecting Presets from the front panel control switch.
Presets are created using the STRATA TX Configuration Utility
software. For more information, see the “Advanced Operation”

3.3 Preparing for Operation
Each installation or deployment will have its own specific tasks
according to the application and the installed hardware.
3.3.1 Mobile Installation
For mobile applications such as aircraft or vehicle, the STRATA
TX System is usually mounted in a bulkhead or compartment
using an MRC Fixed Mounting Bracket. See Figure 3-5.
Mounting brackets are available to mount from one to three
units.
Figure 3-5: Fixed Mounting Bracket
The cabling is permanently installed and power comes from
aircraft (or vehicle) power.
3.3.2 Portable Deployment
For situations where you need to mount a STRATA TX System
and its Fixed Mounting Bracket to an MRC tripod, MRC also
offers a Quick Release. See Figure 3-6.
For situations where you are mounting to another type of tripod
that doesn’t directly accept the Quick Release, consult with MRC
or your tripod manufacturer. MRC has Dovetail Adapter Plates
that will convert some types of tripods to accept the Quick
Release.
Figure 3-6: Fixed Mounting Bracket on Tripod
Note The versatility of the Quick Release Mount and
mating Dovetail Adapter Plate allows the Dovetail
Adapter Plate to be attached to the bottom of the
Universal Mounting Bracket and the Quick Release
Mount to be attached to a non-MRC tripod, or vice
versa.
For optional methods of attaching your STRATA TX
System to a non-MRC tripod, refer to the
“Installation” Chapter on page 6-1 (part of the
STRATA TX System Technical Reference Manual
only)
For portable applications where the STRATA TX System will be
moved from place to place and set up each time, the system will

Routine Operation 3-11STRATA TX Operator’s Guide/Tech Ref Manual
usually be mounted in an MRC Universal Mounting Bracket. The
Universal Mounting Bracket will then be attached to a Quick
Release for easy mounting on an MRC tripod. See Figure 3-7.
Universal Mounting Brackets are required for each unit in the
STRATA TX System, i.e., TXU, TCU, and an optional ACU.
For applications using multiple units such as a TXU, TCU, and
an ACU, a Mounting Plate is also used to provide additional
stiffness. The Mounting Plate typically remains attached
between the Universal Mounting Bracket and the Quick Release.
The cabling between TX System units is also typically left in
place. The power, antenna and audio/video connections are
usually removed at the end of each deployment.
For portable deployment situations where you are mounting to
another type of tripod that doesn’t directly accept the Quick
Release, consult with MRC or your tripod manufacturer. MRC
has Dovetail Adapter Plates that will convert some types of
tripods to accept the Quick Release.
Note The procedures and illustrations contained in the
following paragraph are typical, reflecting use of an
MRC tripod.
Mounting to the Tripod Following are the general steps to
mount a STRATA TX System to an MRC Tripod. These steps
assume the TX System is already assembled into its Universal
Mounting Bracket(s), and that the Mounting Plate and Quick
Release are attached.

Superimposing DC Power In this configuration, DC power is
superimposed with the IF signals between units and there is no
manual control of DC power from the TCU. The DC power is
superimposed on the coaxial cable between the TCU and the
TXU.
To turn DC power on and off, the operator uses the TCU and
TXU front panel PWR switches and either the TCU or TXU
control switch and alphanumeric display menus. The TXU DC
ON COAX switch must be set to ON.
Superimposing DC Power with Manual Control In this
configuration, DC power superimposed on the IF signals
between the units is manually controlled. The operator can
manually turn DC power on or off to the TXU from the TCU or to
the TCU from the TXU using DC ON COAX switches and TCU or
TXU front panel control switches and alphanumeric display
menus.
The DC ON COAX switches provide the manual control and
must be set to ON to allow application of DC power to the TXU ,
and TCU using the control switches and alphanumeric display
menus.
Powering STRATA TX Systems The method you use to power
up your STRATA TX System will vary, depending upon the
following:
• The model of your STRATA TX System, whether or not
you have DC power manual override control.
• The transmitter configuration, whether you are using a
single TCU, a single TXU, or a TCU and TXU
• Whether the TCU and TXU are to be co-located or
physically separated over some distance.
• Whether your STRATA TX System contains the optional
AC to DC Power Converter (ACU).

If you turn the control switch within those 7 seconds, you will
continue scrolling within that set of screens (Monitor or Control).
Unit vs.System Control If you’re using a standalone TXU or
TCU, the menus and options that appear on the display will be
based on the hardware option(s) installed in that individual unit.
When you connect your TCU and TXU, the two units
automatically detect what hardware is installed in each unit, and
automatically configure the menus and options to match the
installed hardware. The connected STRATA TX System then
allows you to control the entire system from either the TXU or the
TCU front panel.
3.5 TXU and/or TCU Monitoring
Operations
The STRATA TX System Presets are set to six possible modes
of operation, based on the options contained in your TXU and/or
TCU. These operating modes are established using the STRATA
TX Configuration Utility software. The operating mode options
available via the Configuration Utility software are as follows:
• MPEG Only ASI Out (MPEG Output mode) (Standalone
TCU Operation Only)
• External 70MHz IF In (Ext IF Input mode)
• MPEG/COFDM IF Out (COFDM - IF mode)
• COFDM Only - ASI In (COFDM ASI In mode)
• Analog IF Output (Analog - IF mode)
• DVB-S (Satellite) (DVB-S mode) (Standalone TCU

3.6.1 Changing a Preset
The STRATA TX is designed to enable you to control operating
settings through Presets stored in the transmitter. The STRATA
TCU and TXU are shipped with factory Presets and can be
customized for the user.
Your STRATA TX System can be pre-configured with up to 9
Presets. Each Preset contains most of the operating settings
needed to control the STRATA TX System. System Presets can
only be defined and changed using the STRATA TX
Configuration Utility software. Presets cannot be changed from
the TXU or TCU front panels.
For information on configuring Presets, see the “Configurator
Reference” Appendix on page C-1 (part of the STRATA TX
Technical Reference Manual only).

3.6.4 Controlling TCU to TXU DC Power on Coax
If your STRATA TX System requires the TXU and TCU to be
mounted in separate locations, MRC recommends powering the
TCU via the coaxial cable from the TXU.
Note When the TCU and TXU are mounted in separate
locations, it is recommended that DC input power
be connected to the TXU.
Since either unit may be powered from the other
unit via DC power superimposed on the coaxial
cable between the units, DC input power may
therefore be applied to either the TXU or the TCU.
If your TXU and TCU configurations contain DC ON COAX
switches mounted on the units, these switches must be set to
ON in addition to controlling DC power superimposed on the
coaxial cable from the TXU to the TCU or from the TCU to the
TXU.
To apply DC power from the TXU to the TCU superimposed on
the coaxial cable between the two units, perform the following
steps.
Notes This procedure must only be performed on
STRATA TX Systems where the TXU and TCU are
physically mounted in separate locations.
This procedure may be performed using either the
TXU or TCU control switch and display.
Apply DC Power on Coax
1. Verify the STRATA TX System is connected and
powered up. See ”Powering the STRATA TX System”
on page 3-12.
2. Observe the Main screen is displayed. See Figure 3-
32.
Figure 3-32: Main Screen
Note If your TCU does not contain a DC ON COAX
switch, go to step 4.
3. Turn the recessed DC ON COAX switch on the front
panel of the TCU until the screw slot points to OFF.
4. Turn the recessed DC ON COAX switch on the front
panel of the TXU until the screw slot points to OFF.
