Depending on the top diameter of the pole a top section of a Rohn 25 can
fit over the top and be securely bolted or lagged in place This makes
the antenna mounting and rotor plate easier to work with and give some
side load thrust support. It also gives the climber a more secure
working area rather than just pegs at the top of the utility pole.

If you have a rotor that has bottom assembly that you can attach to a
mast then buy a 10 ft section of heavy duty Schedule XXXX pipe and
bolt it to the top of the pole. Mount your rotor on that and then the
beam above the rotor on a short mast.
You can put steps in the pole to climb up or rent a bucket truck.
Does Hazer or someone like it make a rail system to raise/lower
antennas on poles?

I just "inherited" a 50' (out of the ground, 6' buried) utility pole

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!
