Now what, I have 3 of the poorest rated DTV converter boxes reviewed here (RCA DT800B) I must admit I was impressed when I first hooked them up, much better reception, more channels, etc. BUT about every other day or two it seems my signal begins to fade on select channels. I make my way up to my antenna located in my garage attic and do some tweaking and it was doing much better..........for a day or two. I do some more tweaking and it works better....again, for a day or two. I am hoping there may be some kind of amplifier or something like that to help pull in the digital signal better. Any help will be appreciated. I have 2 more boxes to get and they wont be the same.
