The run to the top of my tower is 350 ft. The run from the shack to the 
tower is about 225 ft, and it consists of parallel runs of 3-wire indoor 
power cable that lay on the ground. The run up the tower is some really 
nice multi-conductor stuff that I found at a local electronic surplus 
store (we still have a good one in Silicon Valley). I paralleled several 
of the conductors in that smaller cable for the motor, and used single 
conductors for the pot that senses position. The tower went up in 2008, 
and I've had no issues. I haven't even inspected it.
