Review on 📡 Bingfu High Gain 4G LTE Antenna - Enhanced Signal Reception for CPE Routers, Hotspots, and Industrial IoT Devices by Tim Shah

I did a little scientific testing with this antenna, another antenna and no antenna on my Alcatel HH41 LTE modem/router and found that this antenna isn't doing anything useful and the signal is too seems to deteriorate. Both indoors (where the signal is generally lower) and outdoors, connecting this antenna resulted in signal degradation. SINR noise was improved when both antenna wires were connected, but the RSRP signal (which is important in an LTE connection) was worse (drop example, -78 dB with no connected/internal antennas on HH41, down to -83 to -87 dB with them). appropriate). Speed tests have confirmed this: performance with an antenna provided a download speed of 3 Mbit / s, and without an antenna (or with an alternative antenna) - 5-8 Mbit / s.
