what type of antennas are you planning on putting on the pole?
personally i would put a couple of good screw eyes with pulleys and
run some decent rope through them and use it for wires.

I think the word "Lift" is probably the most accurate term to use.
There is a good series *on YouTube referring to "AntennaVater" for the
same type of device.

I want to keep the structure as general as possible so I can continue
to experiment with a broad range of Ham *antennas from DC to light. I
shy away from rope because of the limited life expectancy.

Limited life expectancy????? I am still using some ropes I bought in
the 1960's. Some type of synthetic material nicely woven into a 3/8
inch rope. You need to investigate further, or buy some better class
of rope!

agreed. for something not accessible like that you need decent uv
resistant dacron. that is readily available and lasts for many years
under load. Check it periodically for wear and pull replacements up
as needed without climbing. if the pole is going to have cables
running up to feedpoints then use wire rope, just be sure to use big
enough blocks with the right materials.

I will keep that in mind. I have about 250 feet of blue 3/8" Nylon
that was my primary anchor rope from my sail boating days. It has
served from time to time as a temporary guy line for ham radio.
However, to hoist the fixture a winch with a brake sounds more
convenient.

John, I think my ropes are dacron, as mentioned. That stuff really
lasts!!!! I still have two dacron sweaters my mother bought for me
when I started high school back in 1953. Still fit and have never worn
out. I haven't seen dacron ropes for a long time.

Sure, you've seen Dacron ropes, just not under that name. Dacron is a
trade name for a particular form of Polyethylene Terephthalte (PET), aka
Polyester. Beverage bottles are a big use of PET, but a lot more winds
up as fabric or rope. In film form, one trade name is Mylar.
(originally, it was called Terylene, but Dupont called it Dacron,
probably because it sounded better, and it was similar to Nylon, another
Dupont product..)

You see it labeled as "polyester" rope these days (probably because
DuPont's patents have expired, so anyone can make the stuff, but only
DuPont can call it Dacron)
