The AN/TRC-138 is an air- or vehicular-transportable radio repeater which provides LOS capability in the corps area communications system. It terminates three 48-channel PCM voice systems when used in conjunction with telephone terminals such as the AN/TCC-61 or AN/TCC-73(V)1. The AN/TRC-138 is often used in 12/24-channel mode. The operating procedures are the same for Mast Assembly AB-621/G and Antenna AS-1425/GRC. The components for the antenna systems are stored in the shelter and Power Unit PU-631/G. The AN/TRC-138 is modified to install Radio Set AN/VRC-465 and Power Supply PP-2953/U which are table(s) of organization and equipment (TOE) components not supplied with the assemblage.
