Signal problem & installation technique supporting
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 10 meters at least, with a barrier and not in a same horizontal line.
4. Packed the outdoor connector by waterproof glue, otherwise wet reduce the signal cover area.

5.How Does a Cell Phone Booster Work?
Cell boosters work by pulling in your existing outside signal, boosting it, and rebroadcasting it into desired areas.
Boosters also work in reverse. The unit receives outgoing signals from nearby cellular devices and sends them to your closest cell tower.
There are different types of boosters available that target different needs:
For a cellular amplifier to work, there must be existing signal outside your home, office, or vehicle. Even if weak, the cell signal booster can give it a boost.
