I'm curious.
Your TVFool map is only resolved to the block level. It's probably good, but it would be useful to prepare a more accurate version. Go to
Online TV Maps, enter your address and click "Map This", then switch to "Satellite" at top right, zoom in and move the red pointer so that it is over your house, set the antenna height and let it update, then click on "Make Radar Plot" and post that link here.
In the end you'll probably want to upgrade to a better antenna.
