Some alternatives :
Nylon rope is, in contradiction to polypropylene, UV resistant. It is readily available but a bit more expensive than polyprop.
UV resistant polypropylene rope, but the dye that makes it UV resistant seems to be orange, I don't know if you like that color high up in the air. It is commonly used in boating (safety lines).
Polyester/nylon ropes can be found as heavy-duty fishing lines. It has an even better UV resistance than nylon rope and is very strong.

PS : I am using 5mm (0.2 inch) nylon rope to keep my antenna up and it withstands the sun now for 4 years, I believe I paid about 10-15 Euro for a 100m roll.

Hello Group

Has anyone out there found a low-cost alternative to polypropylene ropes
for use as guys and halyards? The readily available, usually blue,
polyprop is affected by UV and, after a couple of years, becomes brittle
and breaks. If you then handle it, it will tear your hands to pieces,
leaving lots of splinters.

Polyprop is available cheaply at around 10 or 12p a metre and as my VLW
antenna has a total of 8 halyards, I need something low cost. I intend
to visit a chandlers store and seek their advice, but wondered if anyone
has any ideas?
