A partial answer to your questions -- Roof tower.
I have the Glen Martin 9 foot roof tower with a C4 on it using an old
HD-73 rotator along with a discone on top of the whole mess. I
placed 2X8s across 3 of the roof beams (attic side) and used 3/4
inch threaded stock double bolted with lock washers (stainless
steel) on each side. I did not go through any beams with the
threaded stock as I felt that using lag bolts would be 'hit or miss'.
This thing is solid! Been up for a little over a year with no
problems. (And the wind does get going here once in a while!).
Good luck
Bruce, WA3AFS
