can anyone recommend a good tv antenna that actually works. we are about 50 or so miles from the broadcasters, we have a square box antenna from wal mart that sits in the window and it plugs in to an electric outlet, it doesnt do much good a couple channels come in well, a couple are intermittent, another doesnt work most of the time. I had an roof top antenna from years ago ( channel master ) but that was for the tv before the government mandated digital signals, does that make a difference analog or digital tv/antenna ?, anyway couldnt get the channels very well with that either thats why we got the one that sits in the window that no better either. Do they make one that really works ?, not opposed to outside / roof top, or inside, as long as it works well. Thanks.
