Greetwin ASCOM 23dbm Cell Phone GSM DCS Cell Signal Repeater 900 1800 B8 B3 Dual Band Mobile Phone Signal BoosterA cell phone reception booster is generally a repeater system that involves the amplifier adding gain or power to the reception in various directions. Even for a cheap cell phone signal booster, maximum gain differs by application. The work of an outside antenna is to both receive and transmit signals to a cellular tower with enhanced power and sensitivity. Usually, the dB gain is never below 7 dB and can be over 10 dB gain. The system's elements conduit is the coaxial cable. It is also a factor in transmission loss.Production Information
