PRC-786 Transceiver

PRC-786N Transceiver is mainly used to perform manpack communication among squads and platoons in mountains area and jungles. Equipped with a 2.4m whip antenna, the communication range can reach 5 kilometers. Its range can go up to 100km with a 15m slant antenna and 200km with 44m dipole antenna. With a security handset, encrypted voice communication can be performed on it. With an external modem, data transmission can be accomplished.

There is a built-in ATU to accomplish automatic tuning of every kind of antennas. It adopts aluminum alloy telescopic casing, so it is moisture-proof, anti-fog, and anti-salt-fog. It has features of small size, light weight and easy operation and maintenance. It is suitable for field operation.
