Maybe.. but it has not happened to me in a year running this way.. Cambium also didn't think it would happen, but that it _could_ happen if you religiously believe the data sheet for the Backend IC of the PMP450 radios. They ran a small sample of PMP450's at worst case input numbers and didn't brick anything, but I think it pays to be cautious.

That's a scary thought. -----Original Message----- From: Peter Kranz Sent: Monday, April 20, 2015 6:43 PM To: af@afmug.com Subject: Re: [AFMUG] ET Industries beamforming antennas This is a complicated issue.. It depends on how much isolation exist between ports on the ETI beam forming network. For the ETI BFN I use, you cannot have one radio in transmit at the same time another radio is in receive because you may exceed the allowable RF energy into the PMP450 per the PMP450 spec. I can share the bloody details if someone gets to this point and wants more. So this means you cannot run an AP spectrum analysis due to the other radios being in transmit mode. This one of the reasons I would like to see synced PMP450 spectrum analysis where it respects the listen windows. There are other ETI BFNs have higher port to port isolation than the one I use, and might not have this problem.
