Its odd that you mention it. I was having a problem with 59's digital signal but could pick up their analog. I knew what the problem was right away-for me, my antenna was pointed too far South (more like SW-was trying to see if I could get south valley stations). Put the antenna back where it belonged and all was okay.
When I first got my HD set I put my rooftop antenna in the house on a 5' poll. (old style flat wire mesh-and the wife didn't complain either
). It was quite picky as far as digital signals were concerned. I would tilt the pole just a little bit and CBS/ABC (can't remember which one) would fade in and out. I'm about a mile East of 99 at Sierra (side bar 200 yards from where Brian Calhun(sp)
got caught saw your remote truck there) and my HD is just fine.
