Review on Internal Directional Ceiling Antenna Amplifier by Bill Pool

I have tried several different cheaper antennas with my amplifier. Let me tell you what matters, which antennas you use. I used this with a cheap outdoor antenna and it was useless. I bought an outdoor Yagi antenna to pair with and it was an instant hit. I switched from NO SERVICE to 3 Lanes LTE in the basement of a concrete house. I fixed it to the ceiling and just installed the yagi antenna in the window and it worked great. Definitely recommend.
