I would agree using a motorized vehicle, whether it's a tractor or car, to pull
up an antenna or tower section either on a gin pole or other is dicey. The
problem is that you don't have feedback in the line that one can feel with your
hands if something starts to bind. Also there's a point where you want to inch
the load up or down a smidge and you can't do that with a vehicle. With my
tower install, which was all gin poled up, two or three ground crew merely tied
a big loop in the pull line and wrapped in around their hips and just backed up
so they could watch the load being raised. Once up, the installer would ask
down a little and they just leaned forward a little and down it came an inch.
It's real slick and under control. Phil KB9CRY
