See Rohn Drawing C-750112 for the base requirements.
They make NO mention of how much tower can be
raised using the hinged base. Someone told me
it was intended for TV type installations with 3 or 4 sections.
I would be concerned with 5 sections. The forces at the
base are HUGE. On the other hand, one of the locals
did raise a 50 ft tower with a hinged base and a tow truck.

Using an elevated pull up point does help to reduce
the forces at the base.

Mosley sells replacement parts for all of their antennas.
Most of their tubing is in straight sections. Texas
towers sells all sizes of aluminum tubing in 6 and 12 ft
pieces. Short pieces can go UPS. Long pieces go by truck.
