A little background. My 87 year old mother is glued to the TV. It's basically her lifeline when she is home by herself. We've had a couple unusual weather days like last Saturday when it rained in the morning and turned to snow in the afternoon. She lost reception for quite a while that evening and she literally lost her mind without TV. She is very old school and has zero understanding of technology so she didn't understand why snow would affect it. She called Directv 4 times that day and didn't understand why they couldn't get someone out to "fix" her TV. I am thinking about getting one of those covers to try to prevent the snow build up, but have read varying reviews. Does anyone have any experience with these, good or bad?
