Review on Powerful Cell Phone Signal Booster for Home and Office - Enhance GSM, 3G, and 4G LTE Voice and Data Signals Across All Major Networks - Covers up to 5,500 Square Feet by Johnny Wheat

I use Tracfone. Without the amplifier, my phone registered about -110dB in the Network Cell Info Lite app. This was mostly a fluke in terms of connection and clarity, mostly unconnected. I installed an amplifier and antenna and now I get -70dB to -80dB in the room where the indoor antenna is installed. The floor above the indoor antenna has a range of -80dB to -90dB. Now I never drop calls again and I have clear connections. Using the Network Cell Info Lite app was important as it allowed me to find the correct mast and dial in the direction of my outdoor antenna. I have no line of sight from the mast to my outdoor antenna, but my outdoor antenna is about 35 feet up the mast and clear of most nearby obstructions.
