I have an AT&T Home Base 4G LTE WiFi WiFi Internet Router - model MF279. Before installing these antennas I got 2 strips out of 4. After installation, my signal dropped to 0-1 bar. I've moved the unit around the house and even plugged it in outside to test the extra antenna and they reduced the signal in all conditions. They should be compatible with this 4G router but they are not.
