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 =========== http://lf.apersonalguide.co.uk
