Professional China Tri Band Network Booster - KW20C tri band cell signal booster 4G network Vodafone AT&T signal boosting for home 500sqm coverage – Lintratek

Firstly, we need to check outdoor signal strength. It needs at least 3-4 bars phone signal at outside for each signal frequency (attention: if outdoor do not have signal bar, signal booster is impossible to work).
Then, install outdoor antenna at top of house where can get better phone signal and point to Base station.
Also, better to use 15m cable to connect between outdoor and indoor antennas. Most important thing is for the isolation between 2 antennas.
Finally, you can install indoor antenna inside house connected with the AA23 triple band mobile phone signal booster. Then turn on the booster to have a test.

AA23 triple band mobile phone signal booster has AGC (Auto Gain Control) function, this also is the biggest selling point of this series. With AGC function, the machine can identify the gain environment and adjust the gain by itself, this design can really prolong the lifespan of the signal booster.

Lintratek signal booster can be applicated in many different places where the mobile signal receipt is weak.

And for different size of the application, the network solutions are different, for example, like AA23 triple band mobile phone signal booster.
