Thank you for reply. Here's the additional info. requested:
Stations -- need to get the big broadcast stations: ABC, NBC (either one), CBS, PBS, Fox. CW would be nice, but not critical. Others I don't care about.
Dish mount - as you suggest, it is mounted on the south end of my house on the west corner, with a clear view of the sky.
TV Fool plots you suggested:
1. Current satellite mount (roughly 20 feet)

2. 12 feet above peak (roughly 57 feet)

3. 40 feet above ground

One last point - sky around our house is pretty much unobstructed (no trees, etc), but there are some big hills in most directions maybe a two miles away.
Thanks again. I'm grateful for your advice.
