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.
♥ ALC technology used to provide auto amplitude fixing.
♥ Modules structures,making it convenient for installation,debugging and maintenance.
Installation Approaches:
♥ Fix up outdoor antenna reception on housetop and point to signal tower
♥ Connect outdoor antenna to ''outdoor'' port in repeater machine through cable
♥ Connect indoor antenna(s) to ''indoor'' port in repeater machine through cable also
♥ Plug power adaptor into AC power socket and finish installation
Technique Supporting:
♦ If still no signal receipt after activated repeater, please check if outdoor antenna point to
signal tower or elsewhere have strong signal and check if strength achieve -70DBM.
♦If strength is not steady, please check if outdoor and indoor antenna are too close.
Please ensure the outdoor and indoor antenna have distance of 20 meters at least ,
with a wall between and net a same horizontal line
