Download Datasheet (PDF)

The EMTS Telecom Services 450MHz Band Selective High Power Repeaters (HPR) provide an excellent solution to the problem of poor signal coverage for coverage extension and in building & outdoor applications. The HPR amplifies the signals from mobile phones and base stations and can be used in dead areas where service is poor. The HPR is also improving the cellular network's capacity by improving data coverage in areas with limited signal strengths. The HPR is connected toan outdoor donor antenna using a coaxial cable. The donor antenna transmits signals from mobile phones and receives signals from the BTS service antennas placed in dead zones ortowers for outdoor applications. Signals from mobile phones used in the dead zones are then received by the service antenna and transmitted to the HPR donor antenna , which in turntransmits the signals to the base station.
