Up on the Roof

My TV antenna was laying on it's side and not receiving local TV channels. So, up on the roof I went to straighten it up and replace some rotting cable. Well, it still doesn't work. I get audio, but the picture is very snowy. It used to work. Maybe when it fell over something became damaged. I'll venture up on the roof again someday and see what else I can tinker with. In the meantime I'll just enjoy my Directv channels.
