Hey Butch:
when you were installing commercially, did you ever use the patriot
non-penetrating roof mounts?
They are designed for 10 foot satelite dishes and use concrete blocks as
balast.
I wonder if such a structure would do for a beam since a 10 foot dish at 30
feet must surely have more wind loading then a 3 element beam at the same
height.
