After giving up cable because of unrealistic prices, I made many adjustments to my antenna. Currently, I usually get good solid reception. From time-to-time, it still gets very unreliable and intermittent.

I had trouble figuring it out till last night. A windy, rainy storm came through and I started seeing the proverbial pixelating on the screen. Then I finally figured it out. UHF radio waves are impeded by heavy rain. Considering the weak signal to start with, it doesn’t take a lot destroy the TV picture.

Incidentally, it is the same reason satellite TV reception has problems. Satellite uses microwave, which is affected by rain even more. Think it over. It’s why weather radar works. The rain reflects the radio waves.

Just wish cable was not so unreasonably expensive.
