Sounds like you're getting interference from the ethernet cable?
have you tried running the 900 FSK on 10BaseT? That would lower the frequency of the ethernet by an order of magnitude.
Alternately, using shielded cable or putting the ethernet in a metal conduit would also attenuate the ethernet noise.

We have another tower that we have installed 900 FSK equipment on that seems to be causing problems with a 2 way repeater system. The noise floor on the 2 way system is 20 db higher when the equipment is on. The down side to this is the tower owner is the repeater owner and without his repeater his business suffers and the need for the tower is gone. We have in the past had this issue and ran coax all the way up the tower to have only the antennas on top and it solved this issue but I dont want to do this for a FSK 900 radio? So my question would be, what are the odds that the new 450 900 mhz that is only moments away from being released would work without running Coax up the tower? I think this is an issue with the processor in the FSK board not the RF @ 900mhz that is causing the problem. What have others done about this. We have another tower that seems to be on the brink of this same issue as well and I dont want to completely pull off all 900 FSK but maybe I should? Should I just go to UBNT 900 until the 450's release?
