PRC-2505 50W Vhicle-Borne Hopper Transceiver

PRC-2505 VHF 50W Vhicle-Borne VHF Hopper consists of a manpack VHF hopping frequency transceiver, a 50W power amplifier, a vehicle-borne mounting bracket and a center-feeding antenna, etc. 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.
