A local ham here took a smallish crank up tower, built a frame capable
of tipping it over with another electric motor and cable/pulley assembly
by balancing it at roughly it's center of gravity when fully retracted
(think "catapault" here), and put that frame/motor/battery/cable
assembly on a flatbed trailer.... then added simple mechanical/manual
outriggers to the trailer...
It all goes up in a matter of minutes. The expensive part was the brand
new small commercial crank-up.
