Band Selective Bi-Directional Amplifier

SKU: PR-800-33W85

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 the

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

Bi-directional Amplifier (Repeater) fully compliance with DMR and CE standards
IP65 enclosure for indoor or outdoor installations
Comply with TETRA /Apco-25 and DMR/LMR standards and system requirements
Utilizes advanced filtering technology to support out-of-band system requirements
Provide quick RF coverage extension to LMR/DMR/TETRA/P25 Base-Station
Band-selective configuration according to the standard or customized bands
Optional channel selective type with up to 8 DSP filters of 25KHz each
Metal cavity filter technology allows wider receiving/transmitting separation, higher stability, and lower noise figure
Intelligent design provides auto amplitude compensation with a built-in ALC function
USB port for local supervision, with built-in 3G/4G modem for remote management and configuration and mobile app
