I have a router with SIM cards that allow it to receive a cellular signal and I wanted to improve the signal strength of the antennas that came with it, so I gave these a try. When the router was in a certain position, it received -77 dBi and three bars of signal strength. Not bad. Without moving the router I just swapped the antennas on these devices and now it's -72dbi and four bands. For the price, that's a good improvement.
