Product Desciption

Digital VHF UHF Tetra Bi-Directional Amplifier BDA Fiber Optic Repeater

Features

1.Using optical fiber transmission, Long transmission distance, Up to 20km(The maximum optical path loss is 10dB)
2.Using the broadband linear power amplifier technology, ensure the signal amplification without distortion.

3.Modules structure,Multi-duplexer,two ports design,and built-in power supply,easy for maintenance and installation;

4.Avoid the interference of the same frequency, omnidirectional coverage, less interference;

5.Signal transmission is not limited by geographical conditions, particularly suitable for remote towns or complex topography mountain.

6 Power, uplink and downlink output indications.
