Your 10-15' of mast sticking out of the tower plus the rotator being near
the ground requirement makes all of the inexpensive suggestions unsuitable.
If you decided to not substitute mast for tower and either add a tower
section or mount the antenna 31' high with the rotator 5' inside the tower
you probably could use fence post, water pipe and even aluminum which is
easy to obtain in most cities. I would rethink your requirements.

HI Folks:
I have been blessed with 30 feet of tower given to me by a friend. its in
good shape consisting of 2 regular sections and a top section. I also have a
very solid base in place that will support it and it will be tied to the
house at 12 feet up.
My question now is the mast to go in it. I have looked at the very heavy
duty mast such as marketed by DXE and others. Fantastic stuff, but quite
expensive. I am wondering about an alternative material. Such as thick wall
electrical conduit (AKA EMP). What I would like to do is make a LONG mast so
that the rotor is at a height that is accessible at the ground, and run it
up through the tower and out the top with about 10 - 15 feet showing out the
top.
It will be carrying a 3 element tribander, 3 element 6m beam, a 9 element 2m
beam and something yet to be determined on 440. (Probably not real huge)
I need your thoughts and input, obviously I dont want it to fail and damage
anything
Thanks a bunch
