There is a website that will tell you what type of antenna you need for each HDTV station to your specific location. You key in your address and it tells you the azimuth/ distance to your local stations. If I can find it, I will post the link.

It very well could be that for the other stations, you need an outside antenna with more gain. Or, maybe you can't get them at all because of mountains/ hills.
