Review on 📶 TECHTOO WiFi Antenna 2.4GHz 10 dBi - Boost Wireless Router Signal - Secure IP Camera & USB Adapter - Range Extender for PC Desktop, Drone, and More (RP-SMA 2-Pack) (SMA-Plug 1-Pack) by Monty Barganier

I am currently using only one of these antennas connected to my Verizon/Novatel T114 4G LTE Broadband Router. Without an antenna I get 2 or 3 bars at times and download speeds between 1MB and 5MB which is not bad. After connecting the antenna I get 4 solid bars and a download speed of 10-20MB. The difference between day and night is outstanding for such a cheap solution. ADVICE. Make sure you turn off the device before connecting the antenna, or at least connect the antenna and then restart your computer.
