Jim, one amazing tidbit is that the tower goes from full retraction (43
feet), to full extension (170 feet), in 29 seconds. Interestingly, because
of slow ramp up and ramp down motor control, the antennas don't suffer any
extreme stress.

Man, I need some friends like that! Bet you could just put your
shack atop that tower thus running very short coaxes to the
antennas. What a "treehouse!" Jim WA6EKS

At Dayton, be sure to check out the 170 foot Luso tower that a
good friend
of mine bought. It will be on display at Dayton, then
immediately trucked
to my friend's QTH where the base will be waiting for it; all 52
cubic yards
of 4000 PSI concrete. The rotating substructure will also be
installed on
the concrete base, and ready for the crane to lower the tower
onto it. The
tower weighs in at 50,000 pounds.
