How difficult are monopoles to climb and work on antennas while on  
them?  Every time that I see a crew on them they are hanging from a  
crane.

I would plan on mounting the rotator and mast outside of the pole,
rather than inside.

I'd install a couple of "ring collars" - off the shelf weldments used in
the cell business - one at the pole top, and one down 6' or so. To that
you clamp a 4" or 5" pipe mount, which can be plumbed with no trouble.

Then to this pipe you can attach shelves at any height - one for the
rotator, and a couple for thrust bearings for example. You can make this
as heavy duty as you want, mostly with off the shelf parts - just a
little ingenuity and fab work required.

BTW the ring collars come with three faces for clamping stuff, so you
could have some fixed yagis just below the tower top facing in favorite
directions.

Anyway, it gives you way better flexibility and serviceability than
having stuff inside the pole.
