Tetra 380MHz Band Selective 380-385 MHZ 390-395 MHZ Two Way Radio UHF Outdoor Signal Repeater Amplifier with RJ45
The frequency band 380-385 MHz (uplink)/390-395 MHz (downlink) is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Bi-Directional Amplifiers system is to receive low‐power signal from BTS via radio frequency transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.
Product Highlights:
● With modularized design, easy for maintenance
● Software remote monitoring (serial port), easy for maintenance and management.
● IP55 dustproof & waterproof, with low requirements on installation environment;
● With high-linearity power amplifier and high-rejection duplexer, capable of rejecting intermodulation and spurious signals
