I've been having problems with my OTA setup now for some time and just decided a while back not to do anything with it until after the "repack" was finished. Well, "repack" was done last week and I'm getting even less channels than before so it's time to do something. Question on baluns, so do these things either work or not at all? What I mean is can they work halfway and make you think there is something else wrong? The picture below is of the antenna on my roof and notice it's got one of those square baluns bolted on it that looks like it's made specifically for that antenna. I was on the roof last year and replaced and waterproofed the coax connection again and while I was up there I took the cover off that thing and it appeared to have had water in it at some point?? Still working half way mind you, which is why I asked about that.
