..... Pulling an antenna straight up a
freestanding tower is not always easy as some have a very large base

The thought of loosening the guys on a tall tower giving me the
heebie-jeebies notwithstanding, I can offer a suggestion on how to haul a Yagi
up the side of a self-supporting tower. When I installed my Skyhawk on top of
my Trylon tower, I set up two rope slides, from the top of the tower to the
ground. The ropes were anchored to the ground a couple feet away from the
tower by a couple of pieces of rebar; one could also use wooden stakes.
I set up the gin pole atop the tower and let the Skyhawk ride the two
ropes like railroad tracks all the way to the top. I think this technique is
also known as trolleying. Because the Skyhawk went up nose-first (due to trees
around the tower), I had to spin the Skyhawk around a couple of axes once it
arrived at the top. Most folks with room to spare can simply allow their Yagis
to ride on the boom, keeping the elements out of the way of the tower with a
tiller arm and rope attached to the boom.
