Tower Climbing Guards

[WR3O at music-city.tdec.state.tn.us]

As the kids in my neighborhood get older, I think it's time to
consider an anti-climbing guard around the base of my tower.

I have seen articles in the past (long before I had a tower) but
can't seem to locate the articles now.  How do you folks do it?

K1VR adds:  Actually, I've always put my plum bob hanging
from a string on a nearby tree.  That way, when trying to
make the first few sections vertical, I can tap the tower
and I don't have to wait for the plumb bob to stop swaying.
It is just as easy to line up to a plumb bob 10 feet away,
as to a plumb bob hanging from the tower.  The human eye is
able to see parallel lines, or out-of-parallel lines, very
easily, and to a great degree of accuracy.

K1VR replies:  I've had Phillystran, equivalent to Rohn 1/4
inch EHS galvinized steel cable, supporting my 97' Rohn 25
tower since 1981.  The only problem I've encountered is
abrasion.  It was rubbing against a tree branch and I
eventually had to splice the cable.  I've subsequently used,
on another guy where occasional abrasion was unavoidable as
branches bent down under heavy snow loads, automobile gas
line hose OVER the Philly.  The gas line hose has fiberglass
woven into it and has excellent abrasion resistance.
