I've done some checking, and the terrain is just too rough to get to the top of the mountain to the southeast. There is a spot on top of a little mined out plateau to the northwest at
37.149474,-82.844778 (you have to look at the satellite imagery because the terrain features aren't exactly correct). If I set the antenna height at 1 foot it shows that I could get WCYB at a noise margin of about 9. With the antennas that Iceberg mentioned, would this be enough signal to set up a passive repeater (or amplified) to beam the signal back down into the valley below about 750-1000 feet LOS? If so, where would I place the transmitting antenna? The problem I see is that I would have to put the transmitting antenna almost in the same direction as where the signal is coming from.
