SAFETY SUMMARY

The following are general safety precautions that are not related to any specific procedure, and do not appear elsewhere
in this manual. These Safety Summaries are recommended precautions that all personnel must understand and apply
during any given phase of operation and maintenance. Each chapter has other specific warnings and cautions.

WARNING

KEEP AWAY FROM LIVE CIRCUITS

Personnel must at all times observe all safety regulations. Do not replace components or make
adjustments inside equipment with power turned on. Under certain conditions, dangerous
voltages may exist when the power switch is in the off position due to charges retained by
capacitors. To avoid injury, always remove power and discharge and ground a circuit before
touching it.

RESUSCITATION

Personnel working with or near high voltages should be familiar with modern methods of
resuscitation. Such information may be obtained from the Director of Base Medical Services.

WARNING

LITHIUM BATTERIES

Lithium oxide batteries or cells may be used in the receiver-transmitter used in this equipment. They are potentially
hazardous if misused or tampered with before, during or after discharge. The following precautions must be strictly
observed to prevent possible injury to personnel or equipment damage.

heat, incinerate, crush, puncture, disassemble, or otherwise mutilate the batteries.

Do not

short circuit, recharge, or bypass internal fuse.

Do not

store batteries in equipment during long periods of non-use (in excess of 30 days).

Do not

Turn off the equipment immediately if you detect battery compartment becoming unduly hot, hear battery cells

venting (hissing sounds), or smell irritating sulfur dioxide gas.

v

TO 31R2-2TRC199-1

WARNING

VOLTAGES WITHIN THIS EQUIPMENT ARE HIGH ENOUGH TO ENDANGER LIFE.

Covers are not to be removed except by persons qualified and authorized to do so and these
persons should always take extreme care once the covers have been removed.

Page

2-1 WARNING - Installation of the tactical repeater requires a minimum of two people.

2-1 WARNING - Removing the tactical repeater assembly from the shipping carton requires a minimum of two

persons.

2-5 WARNING - Ensure proper use of safety tools (work gloves and hard hat) during assembly and disassembly of

antenna.

2-6 WARNING - Before using the hammer, ensure a wedge is placed in the top of the hammer so that the hammer

head does not come loose, thereby endangering personnel.

3-3 WARNING - Before performing removal/replacement procedures, make sure power is removed from unit.

Failure to do so could result in personal injury or equipment damage.

6-10 WARNING - Before performing removal/replacement procedures, make sure power is removed from the unit

by disconnecting from power source. Failure to do so could result in personal injury and equipment damage.

6-11 WARNING - This equipment is capable of generating RF power sufficient to cause RF burns. During transmit,

care should be taken to eliminate the possibility of touching exposed RF output points such as the center
conductors of coaxial cables or antenna feedpoints.

6-12 WARNING - Before performing removal/replacement procedures, make sure power is removed from the unit.

Failure to do so could result in personal injury or equipment damage.

2-1 CAUTION - Exercise care when removing units from packing material in order to prevent damage to the unit.

3-3 CAUTION - Never apply pressure sensitive tape directly to connectors. This could damage connector pins.

3-3 CAUTION - Package all electrostatic discharge (ESD) sensitive assemblies in ESD bags before shipping or

storing.

3-3 CAUTION - Rough handling may cause unnecessary damage to electronic assemblies.

3-3 CAUTION - Electronic assemblies containing solid-state devices are susceptible to damage from static electrical

discharges. Wear protective clothing and grounded wrist straps.

3-3 CAUTION - Forcing any tilted or cocked electronic assembly into position may result in bent or broken pins.

3-4

CAUTION - When repairing an electronic assembly, be careful that the tool employed does not inadvertently
press against leads, pins, or other parts that are easily bent.

Change 1vi

TO 31R2-2TRC199-1

Page

3-4 CAUTION - Because of the miniaturization of parts for electronic assembly construction, the leads, connectors,

and pins have been stiffened to make them more rugged. As a result, such parts are brittle and will break easily
if bent too often or pulled on too hard. When handling an assembly that has been removed from its chassis, be
careful not to press against the leads and pins. When removing an assembly, be sure to pull it straight out from
the equipment. Do not cock, twist, pry, or carelessly jerk an electronic assembly to remove it from the mounting
or connector.

3-4 CAUTION - The tactical repeater contains components that are susceptible to damage by static electrical

charges. Disassembly of the tactical repeater should only be done at a properly grounded work station.

6-12 CAUTION - The tactical repeater contains components that are susceptible to damage by static electrical

charges. Disassembly of the tactical repeater should only be done at a properly grounded work station.

CHAPTER 1.0 GENERAL INFORMATION

TO 31R2-2TRC199-1

1-1

1-1.1

Radio Set AN/TRC-199 (hereinafter referred to as the tactical repeater) is a communications unit capable of operating
in the 30-88, 136-174, or 403-470 Megahertz (MHz) frequency bands. It is used to extend the communications range of
fixed, mobile, or portable receiver-transmitters. The tactical repeater is COMSEC transparent and provides repeater
capability for all modes without the need for COMSEC encryption/decryption.

1-1.2

(See Figure 1-1.) The tactical repeater includes a tactical repeater assembly, two non-CCI Receiver-Transmitter Sets,
Radio RT-1695/TRC-199 (hereinafter referred to as the receiver-transmitters), three antenna systems, an antenna mast,
three diplexers, a tubular (weldment) frame, a power supply enclosure, and a battery enclosure.

1-1.2.1

(See Figure 7-2.) The tactical repeater assembly includes two circuit card assemblies (CCAs) which are accessible
through a removable cover on the underside of the unit. These are the +15 volt (V) DC-DC converter CCA (A1) and
repeater control CCA (A3). These CCAs plug into the parent board (A4) which interfaces with control panel assembly
(A5), power amplifier assembly (A6), +28V DC-DC converter CCA (A7), the external power supply, and the plug-in
receiver-transmitters. The receiver-transmitters plug into sleeves (A8, A9) located on the left and right sides of the front
panel of the tactical repeater assembly. The power amplifier (A6) mounts on a heatsink on top of the tactical repeater unit.

1-1.2.2

(See Figure 1-2.) The receiver-transmitters provide transmit/receive communication in the 30-88, 136-174, or 403-470
MHz frequency bands. The operating band of the receiver-transmitters is determined by the transceiver module installed.
When the transceiver modules are changed, the tactical repeater must be fitted with the proper antenna and diplexer. The
proper configurations are listed in Table 1-1.

1-1.2.4

(See Figure 1-3.) The tactical repeater diplexer provides a method of using a receiver and a transmitter on a common
antenna. The diplexer, when properly tuned, provides a transmitter-to-receiver isolation of 70 decibels (dB) at any
frequency spacing of 4 MHz or 3% of the operating frequency, whichever is greater. The diplexer has an insertion loss
of less than 2.25 dB between the transmit port and the antenna and less than 3.0 dB between the receive port and the
antenna. The diplexer is capable of handling 60 watts of radio frequency (RF) power in the transmit path and provides
protection at the receive port to limit receive signals to a maximum level of +33 power in decibels (referenced to 1
milliwatt) (dBm). There are three separate diplexers, one for each frequency band. The frequency band of the diplexer
must correspond to that of the receiver-transmitter and antenna.

The power supply assembly provides power for the operation of the tactical repeater. The power supply will operate from
any direct current (DC) voltage between 10 and 32 volts and from 120/240 or 220 volts alternating current (VAC). The
operation of the power supply is controlled by AC/OFF/DC and internal/external (INT/EXT) DC switches on the power
supply. The power supply assembly consists of the power supply enclosure and the battery enclosure.

1-1.2.5.1 Power Supply Enclosure.

The power supply enclosure provides regulated DC power to the tactical repeater assembly.

1-1.2.5.2 Battery Enclosure.

The battery enclosure is a weather-resistant container that can hold either four Lithium batteries (Type BA-5590/U) or
four NiCad batteries (Type BB-590/U). The battery connectors are mounted in the bottom of the battery enclosure box.
(For battery installation see paragraph 2-10.2.)

SPECIAL TOOLS AND EQUIPMENT REQUIRED FOR FIELD
INSTALLATION.

No special tools or equipment are needed for installation and initial setup of the tactical repeater.

2-10 INSTALLATION SEQUENCE.

(See FO-1.) Perform the following procedure to install the tactical repeater. Cables required for installation are listed
in Table 2-2. FO-1 illustrates the required cable connections.

2-10.1 Antenna/Mast Installation.

(Refer to Figure 2-2.) Install the antenna mast and selected antenna as follows:

CAUTION

Ensure proper use of safety tools (work gloves and hard hat) during assembly and disassembly of
antenna and mast.

NOTE

The tactical repeater assembly is shipped from the factory configured for 30-88 MHz operation,
with the appropriate receiver-transmitters and diplexer. If using a different configuration,
substitute the appropriate antenna, receiver-transmitters, and diplexer. Refer to Chapter 6 for
antenna and diplexer removal and replacement. Refer to TO 31R2-2PRC139-1 for changing
receiver-transmitter configuration.

NOTE

The assembled antenna base section/antenna adapter will fit in the mast transit bag (3) so that step
a may be carried out prior to field deployment, if required. When erecting the antennas in high
winds, ensure that a minimum of three personnel are used.

a. Bolt the antenna base section (1, Figure 2-2) to the antenna adapter (2) and connect the antenna ground

strap to its terminal.

b. Select an unobstructed site. Under windy conditions mast raising is made easier if the mast is laid out

on the ground with the base of the mast pointed into wind.

TO 31R2-2TRC199-1

c. Remove both mast sections from the transit bag (3). Note that the socketed end is the lower end of each

section. Place the tubes in line along the ground. Assemble the two tube sections together.

d. Remove the base plate (4), two ground spikes (5), and hammer from the transit bag. Place the base

plate at the mast base, arrowhead style, so that the socketed lower end of the mast will engage in the
heel. Secure the base plate by driving the two ground spikes through the holes.

Before using the hammer, ensure a wedge is placed in the top of the hammer so that the hammer
head does not come loose, thereby endangering personnel.

WARNING

Figure 2-3. Antenna Mast/Antenna Installation (Sheet 2 of 6)

e. Fasten the antenna/adapter assembly to the top antenna section. Connect the top coaxial cable

connector to the antenna and attach cable strain relief to hole in web of adapter. Rest flat edge of
adapter on ground to provide convenient access to guy rope attachment points. Unwind cable along
length of mast and secure to mast at centers of each section. Secure using cable clamps.

Figure 2-4. Antenna Mast/Antenna Installation (Sheet 3 of 6)

f.

Remove three guy rope assemblies (6) and three ground anchors (7) from the transit bag. Disconnect

the first (fixed) snap hook off the winder and temporarily connect it to the base plate. Carrying the
hammer and one of the ground anchors, walk away in the exact opposite direction to the mast (i.e., in
the direction that the arrow head is pointing) unwinding the guy rope as you go, until the ground anchor
radius marker is reached. Drive in the ground anchor at this point ensuring that it leans away from the

mast (approximately 20o from vertical).

g. Using the same guy rope as a radius guide, walk across to the approximate location of the second

ground anchor. Establish the required 120o from the first ground anchor by using the triangular shape
of the base plate as a reference. Drive in a second ground anchor at this point.

Figure 2-6. Antenna Mast/Antenna Installation (Sheet 5 of 6)

h. Repeat step g for the third ground anchor.

i. Disconnect the guy rope used for a radius marker. Attach the fixed (upper) snap hook to the attachment

point on the antenna adapter. Attach the running hook at the lower end to ground anchor 2. Note that
the winder remains attached to the lower ends of the guy rope to prevent accidental loss.

j. Take a second guy rope. Attach the fixed (upper) snap hook to the antenna adapter attachment point.

Attach the running hook at the lower end to ground anchor 3.

k. Attach the upper snap hook of the third guy rope to the adapter attachment point. Unwind the rope

along the length of the mast toward the ground anchor 1, but do not attempt to attach the lower end yet.
Ensure that guy ropes will not snag coaxial cable when mast is raised.

Change 1 2-7

TO 31R2-2TRC199-1

l. Ensure foot of mast is securely located in the base plate heel. While person a pushes up mast head Iwo

Jima style, person b pulls on guy ropes to raise mast to vertical. Person a should progressively walk
towards bottom of mast as it is raised and should hold mast steady as it reaches the vertical. Person b
attaches free guy ropes to ground anchor 1 and tightens all ropes.

m. Connect the 30-88 MHz antenna (SS-1600230-1) to the connector at the back of the power supply using

the coaxial antenna cable (SS-1600315-1). Refer to FO-1.
