STRONG 900MHz interference will kill the GPS signals on the ePMP, PMP, Packetflux and Ubnt. I have two sites where only the ePMP 2000 GPS works (and works awesome). One is a FM tower with a licensed 900MHz feed about 30 ft away and the other is the power company with 900MHz omnis blasting away.
I haven't tried the ePMP 2000 without the sector to enclose the GPS puck so I don't know if is the way they are shielding the puck or the cable.
