I have in my yard two 60 foot steel poles about 120 feet apart, placed
there 40 years ago by a previous ham owner. The old halyards, about
3/4 inch diameter cotton-covered wire (wire core was about 1/8 inch)
are long gone, and I need to find new rope to haul up my wire. I can't
find anything like the old stuff.

I was thinking about using wire rope, the flexible 7x19 kind, maybe
stainless steel, at maybe 3/8 inch diameter. I think that will roll
over the pulleys (which I think are less than 1 inch radius). Given
that my longest wire will have maybe 8-10 feet of poly lines
supporting each end, will wire rope present appreciably more metal at
the ends than the poles themselves will?

Is there a synthetic rope up to the task? Keep in mind that the rope I
need will be running vertically, and when the antenna load is placed
perpendicularly, the loads on the halyard will be in the several
hundred- to thousand-pound load range. Of course it needs to last for
decades or more in the sun.

As always, if you have suggestions that haven't occurred to me I'll
gladly listen to them.

What the blazes are you planning to pull up there? A Sterba for 15
meters or something?
