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 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
Please adjust the direction of outdoor antenna if it cannot call out
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
NOTE
The distance between the outdoor antenna and the amplifier is not more than 30 meters
The outdoor Antenna not close to a large antenna, high-voltage lines, transformers, or metal mesh, etc.
The distance between the indoor antenna and the amplifier is not more than 40 meters
The indoor antennas do not close to the wall as far as possible in order to increase the coverage area
The indoor antenna and the outdoor antenna are advised to stay away from each other for more than one floor distance to prevent cyclic signal amplification
If lack of communication quality, please change the installation position of the outdoor antenna and adjustment the indicate direction of antenna
It is best to enclose waterproof tape at the junction, and prevent moisture narrow the indoor signal coverage area
Try to straight the cable, do not bend more than 90 degree
