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?
