Hi, Steve --
You'll never believe this! I have a draft copy of an article on guy
wires that I wrote from the oft-mentioned upcoming tower construction book.
An SASE will get you a copy.
As you mentioned using cable clamps, it occurs to me that you may never
had any experience with EHS and cable clamps. Forget them (way too much
work) and use Preformed guy grips. Easier and faster. Skip the serving too.

Try about 3/4 out. Have you given any thought to how you're going to
pull the guy wire? One method is to use one of your preforms as a temporary
pull point for your comealong. The other method is to use a real Kliein EHS
cable puller Chicago grip. Tower Tech has them. Typically for first time
tower builders, you'll spend a lot of time putzing around with the guys (too
long, too short, repeat several times) until you get a feel for everything.
Tower pros have a Klien grip and comealong at each guy - the fastest way to
do it.

Count on it (see above comments). It's one of those learning curve
things.
