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
