Review on 📡 High-performance Yagi Directional Antenna for 3G/4G/LTE with 9dBi Gain, Supporting 806MHz-960MHz and 1.7-2.5GHz Frequencies, Equipped with 2FT Cable, SMA Male to TS-9 Adapter - Boost Cell Phone Signal - Tupavco TP514 by Andrew Agarwal

When properly installed, this antenna will perform exceptionally well. I was able to increase my 4G/LTE throughput from less than 2Mbps to 30Mbps over 9km. For best results, use a modem with two antenna connectors and mount the two antennas perpendicular to each other. I used Huawei E5573s-606 as that's what my carrier sells. It is very important to minimize the cable length between the antennas and the modem. Signal loss over coaxial cable is very significant. I used Mikrotik hEX and an open case to get the modem as close to the antennas as possible. I can then send 100% bandwidth with no bandwidth loss over 300 feet using regular Cat5E cable.
