Tetra 400 MHz Two Way Radio UHF Channel Selective RF BDA Signal Repeater Bi-Directional Amplifier is an RF signal booster used to improve radio communications in situations where radio signal.
BDA (Bi-Directional Amplifier) is used to provide bidirectional communication between radio terminals and the base station in order to fit in any kind of environments. It can be used outdoors to extend the coverage range of base station, making communication services available in areas with no or weak signals, which are adopted extensively for tunnels, roads, railways, outskirts areas, congested residential areas, etc.
