my dad WA2FIF(SK) had a telephone pole for his antenna system.
He cut a notch at the top and installed a pulley. You got a hold of
a 50 foot flagpole that the local newspaper was replacing and mounted
the base about 10 feet off the ground. He made a bracket at the top
two somewhat contain the pipe from sideways movement. He had various
antennas over the years nothing very large. All await was in the flagpole.
Worked very well, we did connect the tagline to the mast so when we let it
down
it had a tendency to sway a little.

I just "inherited" a 50' (out of the ground, 6' buried) utility pole (crew
was taking it out and told me that if I'd drag it off the road, I could have
it).
I'm thinking about trying to find a rotator and tri-bander to put on top of
it; but, having no experience with such a setup; I thought I'd seek some
advice first.
So, a few questions.
I'm sure someone has done this before; would you be able to share your
experiences?
I have a friend who can weld anything from steel to aluminum and so I think
we can fab up a mount for the rotor.
Beyond that, thoughts would be appreciated on things like:
Wind loading - how many sq ft (if any) is reasonable before I have to use
guys (for my HyGain AV18HT the building dept made me engineer the base for
90K winds, WITH a "wet stamped" drawing)?
Base - is a 6' hole filled with dirt "good enough" or do I need something
more (if more, would a 6' hole with concrete be sufficient)?
Thanks in advance!
