Our club has a member who loaned out a 2 inch stainless steel pipe for
a mast. It's been *great*. We assemble 5 antennas (6, 2, 222,432, 1296)
on it with the tower propped on a ladder then raise it. Some of the early
attempts resulted in the 20ft mast bending. Not so with the stainless steel
pipe. I'm not sure how much it will cost for me to buy one myself, but I
plan on saving up for one if I have to, its been that good.
