From another thread, there has been a question raised about whether an LNB will suffer desensing or overload when the 2.4GHz uplink transmitter is active.
2.4GHz should not propagate into the LNB input, as the waveguide is well below cutoff at 2.4GHz, although evanescent coupling may be possible? What may be of greater concern is whether there may be leakage into the high gain IF stages in the LNB.
I wonder if anyone has tried this yet (while not pointing the dish anywhere near to the satellite!).
