I used my jeep winch to raise my tower off the ground and onto the
base. The jeep was parked in the driveway, and I pulled the cable up
over the house and hooked it to the top of the tower. I build a
fixture to go on the peak of the roof with a roller on it so the
cables wouldn't drag across the shingles anywhere. This essentially
made the house the (non)falling derrick, or gin pole. A friend
operated the winch via my signals with an HT. It worked slick! Of
course, the tower and the jeep have to be in the right places for
this to work.
When there's a will, there's a way...

You can use a tow truck or wrecker to pull up the tower.

On a similar note, anyone have any suggestions on an appropriate hoist
to use for lifting a Universal 60 ft. tower into place? I'm planning on
putting a "derrick" up made out of a couple of sections of Rohn 25G to
assist in raising and lowering the tower. Universal states the tower
weighs 256 lbs. and one of their engineers suggests attaching to the
tower to be raised at 20 ft. While an electric hoist isn't necessary,
it'd be nice, as long as it isn't too expensive. The derrick will be
approximately 20 ft. away from the tower and the hoist will be mounted
at the base of the derrick, with a pully at the top of the derrick.
General idea is to leave the hoisting cable attached to the tower at all
times, but not holding tension when the tower is fully raised. Other
option is to split the raising cable between the tower and the derrick
with a heavy-duty link and detach when fully raised and let the tower
length hang down out of the way.
