At a clients house, I had two RFX150 antennas wired up to the phoenix connector RF input on the back of the MRF to cover full range of his house. Everything was fine the day I installed it, but I went back two weeks later to change a few things to his system, and I noticed the antenna was picking up interference. I tried moving the upstairs antenna around, but to no avail. I thought maybe one of the antennas was picking up interference from something so I disconnected one, still had problems. Hooked it back up and disconnected the other one. Still problems. So finally I just removed one antenna and hooked up the other one to the 3.5mm RF in jack, and all problems went away. I've used the phoenix connector before with no problems. Could this have been a bad MRF, or did something happen when I had two antennas wired up? This was the first time I've had to wire in two antennas, so I can't relate it to any past installs.
