Tetra Repeater 380MHz 450Mhz (BDA) Bi-Directional Amplifiers for In-Building and Tunnel Communication Systems
Kingtone Tetra Repeater 380MHz 450Mhz (BDA) Bi-Directional Amplifiers for In-Building and Tunnel Communication Systems 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;
- Local and remote monitoring (optional) with automatic fault alarm &remote control;
- Weatherproof design for all-weather installation;
Applications
- To expand signal coverage of fill signal blind area where signal is weak or unavailable.
- Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
- Indoor: Hotels, Exhibition Centers, Basements, Shopping
- Malls, Offices, Packing Lots etc.
- It is mainly applicable to such case:
- The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than 70dBm;
- And can meet the requirement of antenna isolation to avoid self oscillation.
