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.
