Kingtone JIMTOM® B8+B3+B1 20W Tri-band Off-air Band Selective Repeaters Standard Version
Model:KT-B8/3/1RP-B25/75/60-P43
Kingtone JIMTOM® Repeaters system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters 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.
Main Features
◇ High linearity PA; High system gain；
◇ Intelligent ALC technology；
◇ Full duplex and high isolation from uplink to downlink；
◇ Automatic Operation convenient operation；
◇ Integrated technique with reliable performance;
◇ Robust OMT/OMC function with automatic fault alarm &remote control,easy of operate and maintenance,option;
◇ Weatherproof design for all-weather installation;
◇ Compact size, Tri-band in one cabinet;
