Agreed.

I would be curious how things perform if a new or known good coax from the antenna to a single set were installed as a test.

Something does not add up here. The signal levels shown on the TVF report should be in excess of what is needed to overload the CM7778. (Or somebody tell me I'm doing the math wrong.) That suggests that there has been a long standing problem with the antenna, matching transformer, cables or connectors. Such a problem may have been masked by the gain of an amplifier that should not be needed.

An un-amplified antenna with a few dB of forward gain should be capable of driving a passive 4-way split.

Time to critically look at each component and connection...
