the latest signal repeater vhf outdoor (repeater vhf, signal transfer, repeater outdoor)
BJ-851 is globally the only mini duplex and single-mode antenna units which consists of duplexer, receiver, transmitter, CPU controller ect. CTCSS and DCS are built in. Aluminium diecasting outer cover of vehicular was adopted. Full duplex communication can be achieved between two duplexers and single set can be used as repeater also. It can be increase the communication distance. DCS/CTCSS are built in.
