Could also be something inside the 300 to 75 ohm transformer doing the same thing, if you have an external one.
The cable from antenna is a short homemade quad-shield that I personally made. The connecting coax is pre-made dual-shield going directly to attic running approx. 30ft before into the dist.amp.

Two weeks ago, I ran a coax directly from the antenna to one TV.
(No pre-amp, dist. amp, splitters, etc...)
Early evening I had a few (H-VHF) stations completely dropping out , but all UHF seemed OK. The only thing I can think is that the temps would drop from 90+F to 60s.

The balun was included with the antenna; could these actually go bad or be faulty under cold temps?

Thank you for your input!
