And maybe how to interpret the image on the details page?
I'll try.

Here is the map:



If you click on a callsign in your tvfool report you will see the profile. The transmitter is at the left end and your location is at the right.



The black arc that you see at the bottom of the image is the curvature of the earth, which starts to interfere with the signal at about 70 miles.

The color code for the image is here:

In very rough terms, the colors can be broken down as follows (not related to Antennaweb):

- White is extremely strong. Beware of signal overload on amps.
- Red-yellow-green are all quite strong. You can expect reasonable coverage with an indoor antenna.
- Cyan is where it's advisable to move the antenna up to the second floor or attic.
- Blue is where it's probably necessary to install a good antenna on the roof.
- Purple is quite weak and you really have to work at it for any chance of reception.

Here is the coverage map for WRTV ABC. You can see that the signal is pretty weak by the time it gets to your location. The color code is the same.
