Clay,
I remember in the old days that 10 % of the pole needed to be in the
ground. At the old N6DX contest station, there were two 80 - 90 ft poles,
but because of the large antennas on the poles, they were in the ground
about 10 ft. They will hold up almost anything, and they do sway in the
wind.
If you can get any cresote, or its equivalent, you might paint over any
cracks and splits, especially the bottom part that goes into the ground.
If the pole doesn't all ready have steps, I'd suggest you add them while
the pole is on the ground. You might be able to get them from your
telephone or electric company.
Seems you have enough info provided to purchase or build your own
antenna/rotator mount.
Good luck!
Ray,
N6VR
