High Power Channel Selective Bi-Directional Amplifier

Download Datasheet (PDF)

The EMTS Telecom Services Ltd. DMR channel selective Power Bi-Directional Amplifier (BDA) provides an

excellent solution for in-building applications for poor signal coverage or outdoor coverage extension. Typical

applications are airports, tourism regions, tunnels, factories, mining facilities, villages, hotels, exhibition

centers, basements, shopping malls, offices, parking lots, and others. With the BDA, the DMR/TETRA/P25

operator can quickly expand a base station's service area by filling in coverage holes caused by terrain,

buildings, or tunnels. The BDA amplifies the DMR/TETRA/P25 handset signals and base stations and can be

used in dead areas where service is poor. The BDA is connected to an outdoor 'donor' antenna using a coaxial

cable. The donor antenna transmits signals from the handset and receives signals from the DMR/TETRA/P25

BTS. Easy installation, lightweight design, and very friendly GUI make our Repeater easy to use and install. Its

channel selective functionality enables to amplify only the selected up to 8 channels (option for 16 or more
