[tomfoolery]

I don't know anything about reception in that area, but I have relatives in the Houston, TX area who have a similar report, with similar distances, and get all they need with a $12 Radio Shack rabbit ears unit with UHF loop. So I don't think the report is out of line, though the high-vhf stations may need more gain than a single dipole can offer, especially those in the yellow.

All the UHF stations might benefit from something more directional, like the Terk HDTVi (the unamplified one). I would probably give a cheap rabbit ears a try,, and go from there. Return it if it's not good enough. You may find you get enough without going further, though.

Edit: Click on the line containing a station of interest to see why it's line-of-sight or 1-edge. Looks like the transmitters are on a mountain, and your house can 'see' them (LOS), while only some in the yellow have 1-edge conditions.

Of course, a decent outdoor will be better than an indoor, but I'll leave it to others to make specific recommendations.
