I'm trying to pick up a specific channel. I've attached my chart from tvfool.com I'm using a Channel Master 4228HD antenna http://www.crutchfield.com/p_6594228HD/Channel-Master-4228HD.html?tp=3261. I'm playing with it, and right now I can get channel 10 in perfect. As far as alignment goes, if I'm getting 10, shouldn't I also be getting 23 in as well? Is the fact that I'm getting 100% on 10 and 0 on 23 an indication that I'm NOT going to get 23? Would a different antenna maybe have better results, or should I just stop trying at this point? And yes, Directv does provide my locals in HD, but they don't provide them all, and the ones that they do, I'd like a backup for.
