Like when you stop at a red light and your FM radio fades... pull ahead a foot or two and it clears up. When I run the numbers in RM, I always move the elevation up and down a few metres to see if it is on a null point. I have read stories of installers having to lower an antenna a few feet to improve the signal. Sometimes it is to get below noise but not always. I'd guess sometimes raising it a few feet would have had the same effect.

It's cutting the fresnal smaller because of the height and distance. I thought that at first too, but the one with greater fade margin has less fresnel clearance. And the spot you speak of is the only spot that the fresnel has any encroachment. Just seemed weird to me.
