Used to be pretty commonplace, but that was before the "big yagi" era.
I've seen many which merely had a 2" pipe bolter to the top, with the
rotor on the pipe, but don't think much of that idea.
The one I remember which seemed to overcome the problem was a buddy in
NC who "telescoped" a piece of Rohn 25 ( I think ) over the top of the
pole so that about half was over the wood, and the rotor plate mounted
just above the top of the pole. Seemed to work well.
With the difficulty involved in climbing the thing, plus the other
factors, I would think Rohn 25 would be a better and cheaper answer.
