You either have equipment failure or overload from very strong TV and FM signals. I don't know why teleview suggested a very large all channel antenna like that. You don't need VHF-Low, unless you want analog 4.

I wonder if some trees have now grown into the signal path?

scroll down to Trees and UHF

WATC has a Noise Margin of 74.8 dB, even before adding the antenna gain.

WRDA FM 105.7 has a signal strength of -15.5 dBm. You should insert an FM trap, or two in series, between the antenna and the TV. See attachment 1.

It might even be necessary to insert an attenuator before the TV.
