Hi, I live in St Louis, Mo. zip 63129. Charter cabel dont carry CBS in HD anymore. For the Super Bowl I had a company install a antena on the roof. Got to watch the game!! however for the past week i cannot get a signal. Anyone in town have this problem? is there a way to fix it, I have no idea how to do this. I would rather not have the installer come back out and point it, dont want to spend the bucks for it. now that JERICHO is done , i hardly ever watch CBS. Thnaks for any help you could give.
