I am from zip 37841. I have 11 channels that i can get with my antenna, including 4 channesl of ion. I was watching it one night last week with about a 60 signal. the next night i turn it on and nothing, like a 3 signal. so i do some turning and rescanning and still isnt doing anything. i cannot figure this out as ion was one of my strongest stations. the same thing happened with abc, luckily i got it back this morning. would the kind of converter box i have have anything to do with it? are there stronger boxes that might help to get better signal or possibly more channels?
