Using the TVFool Interactive map, I tried different antenna heights. Please keep in mind that the computer simulation doesn't know about the trees and other ground clutter, it primarily uses elevation.









The Richmond channels get a lot better with the increased height, but 7 and 9 from the north stay about the same because they are blocked by the curvature of the earth.
