AN/PRC-77 TACTICAL
RADIO
SET
|
| |
|
The
AN/PRC-77 Series Radio provides a short-range, two-way voice
communications in manpack portable and vehicular
configurations. The AN/PRC-77 supersedes its widely used
predecessor, the AN/PRC-25. It is physically and
electronically interchangeable in all manpack, vehicular and
fixed radio installations that previously utilized the
AN/PRC-25. It provides greater reliability, longer battery
life, and the important improvements in spurious response,
oscillator radiation and desensitization, plus its
capability for use with "secure voice" systems, represent
the very latest development in the family of manpack and
vehicular FM communications. The equipment can be remotely
controlled up to two miles with the AN/GRA-39 Remote Control
Group and is capable of automatic retransmission (relay
operation) when used with the MK-456/GRC Retransmission
Cable Kit. New improvements and modifications to this basic
radio set offer many improved features such as: encryption,
anti jamming and 25 MHz channel spacing.

The
ST-138/PRC-25
Harness is a cotton duck back pack. It is sewn to secure the
receiver-transmitter so that it can be carried on the
operator�s back.
The
CW-503/PRC-25
Bag is a sectionalized canvas carrying case used to store
the two whip antennas and the handset.
The
AT-892/PRC-25
is a one-section, three foot, whip antenna. A spring at its
base allows the antenna to be placed in a vertical position
no matter what the position of the receiver-transmitter. It
is constructed of steel tape and can be folded for storage.
The
AT-271A/PRC
is a six section, tubular, folding whip antenna. A stainless
steel, plastic-covered cable (or braided plastic cord) under
spring tension is threaded through the sections to keep them
together when assembled for operation and prevent their
separation or loss when disassembled. Spring tension is
provided by a spiral spring in the base section. An antenna
top cap installed on the tip of the antenna provides
protection for personnel.
The
AB-591/PRC-25
is an antenna base that will act as a rigid support for the
tubular six section antenna.
The
H-189/GR
Handset contains a dynamic microphone and receiver for
transmitting and receiving signals. A push-to-talk switch is
mounted in the handle. The connecting cord is retractile and
terminates in a five-pin connector.
