I was expecting to use them and handle up to 4 departments at a time, but that's not the case. What they gave me was a stable 3 bars. Without antennas, my USB tethering switched from 3 to 1 at times. Now they need to be adjusted a bit. Initially your bars will go down so make sure you keep them about 22 inches apart and rotate until your bars are up and staying stable. My application isn't in an ideal cell coverage range either, so overall this product did the trick. .
