Your question depends on the Tx/Rx frequencies. Isolation is measured by the return loss of the OMT of the feed in both H & V and is usually conducted in a range test. I'm speaking of microwave frequencies way above UHF (Ku-Band for example) using parabolic antennas.
The isolation is...
I've seen microphonic-related problems on certain modems and LNBs (C-Band). Anyone here point me the way to solve this problem, or point to a reference that not only describes it, but also offers at least a theory of its cause? Thanks
