Functions

In some places such as tall buildings, basement of the room, countryside, your cell phone can not receive the signal well. Then, a repeater can help you. Mobile phone signal repeaters are able to pick up weak cellular signal from a BTS and transmit them to your mobile phone, and then transmit a more powerful signal back to the BTS.  Mobile phone signal repeaters overcome the problem of dropped calls, limited range and slow data rates.  

Our booster can increase the signal by 500%

Note:

1 If there is still no signal receipt after installing the repeater, please check if the outdoor antenna point to signal

tower.Please adjust the direction of outdoor antenna if it cannot call out.

2The outdoor antenna is prohibited to be close to another large antenna, high-voltage lines,transformers, metal mesh, etc.

3 If strength is not steady, please check if the outdoor and the indoor antenna are too close.

   Please ensure the outdoor and the indoor antenna stay away from each other at least one-floor

   distance to avoid cyclic signal amplification.

4 Please make the indoor antenna away from the wall as far as possible to increase the coverage area
