I agree with Bill, I have installed many large yagis by dropping the guys,
one set at a time and pulling the antenns straight up with very little
assistance. It's easier if you install the antennas from the top down,
however things don't always work out that way and a person on the ground can
usually pull the antenna far enough away from the tower to go around the
obstacle. This method will also work with a pier pin base as long as you
have at least one set of guys attached. Pulling an antenna straight up a
freestanding tower is not always easy as some have a very large base
section.

Wrong. I and many other hams have successfully raised the antennas, by
simply dropping the guys, either one group at a time, or by dropping all
guys
and
bringing it up the side of the tower. Of course common sense is of utmost
importance in doing so....don't do it in heavy winds and so forth.
However,
it can be done on towers not installed with a flat plate or pivot bases.
There are a couple of other ways to go on this without having to fight the
guys...trams, and assembling the antennas on the tower.
My plans for raising up all the antennas out here in KH6 is to bring them
up
the side of the 150 foot tower one at a time.
