GSM  Band Selective Repeater

Technical Features:
*Receiving and sending separation,low require for Ant isolation,making it  convenient for installation.
*Mini design with metal cavity filter technology inside.
*Full-duplex&dual-port design,and built-in power supply,making it convenient  for installation.
*Allowing for continuous gain adjustment 31dB by 1dB step.
*ALC technology used to provide auto amplitude fixing.
*Modules structures,making it convenient for installation,debugging and maintenance.
