Hi Stephan

Your posts seem to inply that the receive antenna will "see" the 20 meter
high transmitting antenna when the receiver antenna is in the shadow of the
80 meter hill. It seems that the receiver needs to be out of the shadow of
the hill unless you are able to estimate refraction from the hill.

But, your aparent confidance in the statement "0 feet" makes me wonder if
I have this problem wrongly analyzed. I have so much confidance in Richard
Fry's data that I had accepted his estimation of 270 meters to be as close
as you can estimate.

Do I misunderstand your post about what minimum height is needed?
