LF: Guy ropes

["John W Gould" <g3wkl@btinternet.com>]

Yet again the wind has taken my LF aerial down.  It's always the same way
with polypropolene rope just not strong enough, either loosing its strength
though UV exposure or in last night's case sheer lack of tensile strength.

Any suggestions as to a stronger guy rope - the rope goes up though a tree
and over the fine branches at the top of the tree.  Thus, there is a fair
degree of movement at times.
