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 can not call out, please adjust the direction of outdoor antenna. If strength is not steady, please check if outdoor & indoor antennas are too close. Please ensure the outdoor and indoor antenna have distance of 20
