PRC-2189 Vehicle-borne VHF Hopping-Frequency Transceiver consists of PRC-2188 man-
pack VHF hopping frequency transceiver, a 50W power amplifier, a vehicle-borne mounting
bracket and a center-fed antenna. It can be installed in tank, armored vehicle, mobile artillery,
armed helicopter and navy ship to perform voice communication and data transmission. Fixed
frequency communication, fixed frequency encrypted communication as well as hopping frequency
communication can be accomplished effectively with it. It can be grouped in a network with other
transceivers. It can ensure fast, accurate, and reliable communication under electromagnetic
interference and meet the requirements of mechanical army and modern battle.
It has the functions of frequency hopping, security, data transmission, remote control and
retransmission.
