FAQ

outdoor 2w/5w/10w/20w high power gsm900 repeater with duplexer Installation:

1.If still weak signal receipt after installation, please check if outdoor antenna point to signal tower correctly or elsewhere has stronger signal and confirm signal strength achieve-70dBm.

2.If still have no signal after installation, please check our device power adapter whether connected perfectly? And connectors connect well.

3. If strength is not steady, please check if outdoor and indoor antenna is too close; please ensure outdoor antenna has distance of 40 meters at least, with a barrier and not in a same horizontal line.

4. Packed the outdoor connector by waterproof glue, otherwise that will reduce the signal cover area.
