[TowerTalk] ridge top derating factors

[Curtis, David B]

EIA-222-F lists Mariposa county California as an 85 mph county, 85 is lowest
possible.

But... I have a ridge-top location. Therefore, I need to derate for wind
acceleration over the ridge. I've read Leeson's book and done some other
research, but it is not straight forward and I couldn't convince myself that
I know how to calculate the correct derating factor. So, my question to the
group: How can I arrive at the right derating factor?

73, Dave N6NZ
