Ok Warren,
Its the kevlar - carbon fiber - that i'm concerned about .. has it any
dialectric properties in the hf spectrum ? I could do with geting hold of
a lenght , see if it passes the microwave oven test ?
When you say for antenna use , you mean as support rope / insulator /
element configuration ?
Ive got to drop the mast ( 2 x 20 ft alloy poles) and replace the top
section , so want to re-guy it at the same time , the mast is on a
insulted mount and also supports the wire antennas,
G ..

Graham,
Most kevlar rope for antenna use has an outer covering of Dacron for UV
protection so it will be non conductive.
However, I don't think its a good idea to guy the very top of a vertical
especially if high power is in use, particularly in rainy conditions.

Looking to replace the guy ropes on my vertical mast , the blue polyprop
is
showing signs of over exposure to the sun and starting to fray
I'm wondering if the 'kevlar' type of ropes would be suited, as the mast
is
a radiating element ?
But as far as I know, the rope conducts electrically, which would not be
a
good material to have in the saturation field of the element
How conductive is the 'rope' ? is it just a leakage or a full low ohm
situation ?
Tnx - G ..
