Need some help or just a question I guess. Why is it I can pull in 54-1 and 31-1 at around 70% but get nothing on 19-1 and 48-1. Are they that low on power? I really need 19-1 for my NFL. I was getting them at a very low 29% but it was at least locked in. After the snow last week I get nothing. Did it damage them somehow? I've tried adjusting my antenna but still get 0.
