RCTGX

The GSM selective band repeater is applied specifically in small area indoor DAS system. It provides quick coverage solution for weak signals and block zones reducing drop/off calls; it eliminates the signal dead spot, rejecting the interference and providing a stable signal communication for cell phone users. The GSM selective band repeater has power supply and output power indications; with ALC function design provides the high reliability and stability and low interference to BTS. It has compact size, low power consumption and easy installation. The GSM selective band repeater can be used in basements, cars, elevators, parking lots, villages, tunnels, mines, clubs, residential houses, countryside, tall buildings, vessels, underground facilities or any other place.
