Review on 📶 SuperBars Home Cell Phone Signal Booster - 6,000 sq ft Coverage, 2 Indoor Antennas, App Remote Monitoring, Works with All U.S. Carriers: Verizon, AT&T & More, FCC Approved by Charles Julian

Here's what I did: I have a Google Pixel 4XL phone. Before setting anything I went to Settings > About Phone > Sim Status, this gave me the actual signal being received by my phone. I walked around my house and stopped in several places until I found the best signal. I had -95. I installed an outside antenna at the end of the house where I had the best signal. He sent an outside antenna to the nearest tower. (I could see the mast lights at night) I routed the cable from the outside antenna through the attic opening to the spot I had chosen for the amplifier. My amp is in the back room with my air conditioner. The distance between my outdoor antenna and the amplifier is about 30 feet (horizontal) and about 10 feet (vertical), I was looking at the amplifier in front of my outdoor antenna. I installed both indoor antennas. Antennas that came with my custom unit in my attic as I didn't want to drill holes in the ceiling or walls for this. Both antennas are angled down and about 20 feet apart. The indoor antenna closest to the outdoor antenna is approximately 25 feet (horizontally) and 3 feet (vertically) below the outdoor antenna. I had no problems for about a week after installing my amp. The signal went from -120 indoors to -90 in most places. Much better than before. Speeds have also increased. I had a place in my house that had pre-install speeds; 9 Mbps down and 0.75 Mbps up. Speed was now 35 down and 12 up at the same spot. I was very surprised by this increase. Remember that you need an outside signal to be able to amplify. If you don't have anything out there, he has nothing to increase. Small adjustments to the outdoor antenna can make a big difference. Hope this explanation helps. If you need write to me in messenger, I will try to help further.
