Careful when using these charts. The signal levels are for an antenna
mounted 30ft above ground level using a "traditional" antenna model,
which means a rather large yagi antenna with a substantial amount of
gain as described in:
http://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet69/oet69.pdf
If you have a small, low, or indoor antenna, your reception will be
worse.

That wasn't the one I meant, but it looks good. Looking at the results
right now. Nice. Thanks.

Most of the online maps are based upon the FCC coverage maps, which do
not include the effects of hills, mountains, antenna downtilt, and
differences in elevation:
http://www.radioworld.com/article/FCC-Maps-Show-Where-DTV-Coverage-Doesnt-Match-Analog/200467
...this data is based on the horizontal plane azimuth pattern with
the elevation pattern otherwise ignored in favor of a default
pattern. In areas with mountaintop transmitter sites where
mechanical beam tilt is used, such as Los Angeles, these patterns
will not match reality. The results will be more accurate in "flat
land" areas like Florida or areas with low mountains where
stations are unlikely to use mechanical beam tilt on their
antennas.

You can get local coverage maps at:
http://transition.fcc.gov/dtv/markets/
http://www.fcc.gov/digital-television
and customized maps at TVFool, AntennaWeb, FCC, etc. However, all of
them are based on the same FCC data, with the same limitations. The
maps also tend to be a bit more optimistic than reality because these
maps also are used by marketing to calculate the number of possible
viewers and listeners for advertising proposes.
