Band Selective Bi-Directional Amplifier

Download Datasheet (PDF)

The EMTS Telecom Services DMR channel selective Power Repeater / 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 districts, 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. Easy installation, lightweight design, and very friendly GUI make our

Repeater easy to use and install. Its Band-selective functionality enables amplifying only the selected band.

Key Features

  • Bi-directional Amplifier (Repeater) fully compliance with ETSI, 3GPP, and CE standards
