UHF Duplexer Repeater TC-851

UHF Repeater TC-851 1.Frequency Range 400-470MHZ 2.Frequency Spacing 10MHZ 3.Duplex Band Width 1MHZ

radio repeater TC-851 is globally the only mini-size duplex and single-mode antenna units.

TC-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 advantagessuch as easy to operate and convenient to use.
