We did it a few times a month with 25G by attaching about
2/3 of the way up....a single point attachment....but that
was with perhaps a half dozen VHF/UHF monoband yagi's and
logs for TV channels.

I just did it with a 150ft 19" face tower by attaching at
100ft. I'm sure it would have handled more.

All you need to do is wrap the whole tower and weave around
a leg below and above a crossbrace so it doesn't slip. Watch
it when you start to lift for bending.
