Many people argue for the use of a backstay because, as Phil says, this
puts a lot of stress on the mast. W9LT (now WA7LT) taught me how to do
this using a single cable and what he called a tiller, which is a short
piece of tubing u-bolted to the boom like another element. Put a pulley on
the end of the "tiller," also running on the tram line, and you can adjust
how high the leading ends of the elements ride so they don't hang up in the
top guys as you approach the tower.
