Review on 📶 Enhance Your 4G LTE Connection with Bingfu 3dBi External SMA Male Antenna (2-Pack) – Perfect for Wireless Routers, Industrial IoT, and Cellular Security Cameras! by Quinton King

I live far from the internet (other than satellite) and have tried many things to improve cellular coverage on my old AT&T MF279. These antennas reduce the noise level from 90-95 dBm to 87 dBm. I tried with them, without them, here, there, pointing here and there. Yes. Placing them horizontally and perpendicular to where the FCC says the closest registered AT&T tower improved my situation. That few dBm made a big difference for me and I never thought it would. Hardly needs to have crossed any threshold or anything. In any case, thank you. The family is very happy.
