I like the way you think, John. THAT is engineering.

Subject: Re: [Elecraft] Thanks ref - Antenna wire question for long spans
John & others
I am going to go in another direction on wire size for long spans.
I have been using the silky #18 and #26 from the wireman for all my
antennas. The trick for keeping them
up is to use a Dacron rope for a messenger line that supports the very
light wire. With the rope strung between
the supports with a lot of slack, I attach small rings of gray PVC
pipe. A small loop of the rope is pushed through
the ring and then the ring is passed through the loop. The antenna wire
is hung in the rings with any feed line supported
by the rope. The wire carries no weight.
When the trees sway in the wind the rope can break. I just let it, but
force it to break where I want.
I make a loop with about 3 ft of the rope and tie it with a short length
of cotton line. The cotton being
weaker than the Dacron will break first allowing the loop to add about 3
ft of slack to the antenna.
