[TowerTalk] desireable features in a crank up tower

[tongaloa]

machinist / welder guys I know are interested in manufacturing
another product and I suggested they look into doing a tubing type
nesting mast for radio antennas.

wonder what features folks are looking for in one. will likely
do a 70' 3 section  first as that seems to be a popular height and
makes  sense from minimising material waste based on stock sizes.

positive pull down?
ladder hooks?
optional tilt base?
rotator mounting options?
a few degrees adjustment range for plumb?
capacity/windspeed?

want to keep initial foray simple so no rotating masts, at first.
