CHAPTER 1.0 GENERAL INFORMATION
1-1
DESCRIPTION AND PURPOSE.
1-1.1
Equipment Function and Purpose.
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
Equipment Description.
(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
Tactical Repeater Assembly.
(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
Receiver-Transmitters.
(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.

NOTE
The CCI Receiver-Transmitter RT-1696/U(C) shall not be used in the tactical repeater.
1-1.2.3
Antenna Assembly.
The antenna system for the tactical repeater provides full-duplex transmit and receive capability over one of three bands
of operation. The selected antenna is mast mounted. Three antennas are provided to cover the three bands of operation.
Refer to Table 1-1. A mast is provided to elevate the selected antenna up to 10 feet (in 5 foot increments) to increase
transmission range and quality of transmitted and recorded signals.
