polyester because it had the best score against sun rot.  I have been using

Subject: LF: Rope?


I am refurbishing one of my antenna supports. It is supported by a
large tree and is raised and lowered using blue polypropylene rope
(from B&Q).

The rope shows signs of deterioration - presumably from UV - and I
wonder whether I would be better using white polyprop, or nylon,
rather than blue polyprop.

Nylon is a lot more expensive - is it worthwhile? I understand than
nylon is stretchy - is this a problem? Does nylon have a similar
breaking strength - the antenna is lightweight but takes some wind-
load and in any case I don't want any accidents, so over-engineering
is the order of the day.

Any advice from those more knowledgable / experienced than me?

Mike, G3XDV
