When we were doing it [at a little independent telco in the 70's],
it was pretty much 'by guess and by gosh'- but some engineer
probably has figured out the pounds of tension produced by a span
of wires at a certain angle and a certain length. * *That strain
will help hold a smaller lighter load in a different direction.

I have a related question: How are the guy wires held in the ground?
What keeps the steel loop from coming out of the soil?

They have "ground anchors". They are spirally wound steel rods. Just
screw into the ground. Or sometimes a helix.
Similar to this.

That seems to be it, thanks. It helps when you know what they're called.

I can't imagine the force it must take to screw these things in, especially
into the heavy clay soils of my area.

"Screwpile" appears to be a UK term. I find more American hits using the
terms "helical anchor", or "helical anchor guy wire".
