The outdoor antenna should be on the housetop, at least 10 meters far away from the indoor antenna(s), better with stairs or wall(s) in between. Put the indoor antenna(s) in the middle of room, far away from the window and door.

2. If still no signal reception after activating repeater, please check if outdoor antenna points to signal tower or elsewhere have strong signal and check if strength achieve -70dBm. Please adjust the direction of the outdoor antenna until it catches good and steady signal.  To ensure the result, the outdoor signal should be as strong as possible.
