Review on 📡 Bingfu 4G LTE Antenna 8dBi Magnetic Base MIMO SMA Male Antenna (2-Pack) for Enhanced Connectivity with 4G LTE Wireless CPE Router, Cellular Gateway, and Industrial IoT Router by Eric Teshome

I tried 6 different antennas advertised as 4G ranging from 3dbi to 10dbi. Based on my testing, their stated dbi meant nothing at all. This antenna proved to be the best here and by a clear margin. The only thing that made me different was that it had a stronger magnet. They don't stick to your car in the wind while driving, so I keep them behind the rear seat headrests most of the time. Then when I park, when I need a good signal for work, I attach them to the car. They work much better outdoors than in the car, but they work quite well indoors.
