What I'm looking at is a self-supporting tower: 4-section 55ft mounted
on a 4ft "stand"; it tilts over at that point.

They tell me 20-30min by hand, but I'll probably get the electric winch
option for cranking up and down and leave the tilt-over mechanism (used
less often) hand operated.

Other people have written privately to say that it depends on how much
ice and whether the tower has a positive pull-down mechanism.

I looked at the Heights towers again after reading the lousy reports on
the US Tower products (especially inadequate installations and other
documentation); one private email referred to them as "US Trouble."
