About 2 years ago I lost KSTP (channel 5 or 50 digital) I got it real good,now I only get about a 4 to 50 on my digital signal, this is not enough to get the station. I get all other stations, (2,4,9,11,17,23,29), I also don't get channel 45 which is a sister station of channel 5. I have several other digital conversion boxes around the house and channel 5 comes in strong on these even with a weaker antennae like rabbit ears. Any information is appreciated
