Radio repeater BJ-851 is globally the only mini-size duplexer and single-mode antenna units.
BJ-851 is globally the only mini-size duplex and single-mode antenna units which consists of duplexer,
receiver, transmitter, CPU controller ect. Aluminium diecasting outer cover of vehicular was adopted.
It can be used both in cars and in a fixed place, which is suitable for emergency situation.
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, the same time it has many advantages
such as easy to operate and convenient to use.
