From Tom, G3OLB
Be careful using polypropylene as guys for masts over a long period.
They degrade with ultra-violet exposure and become very weak. I lost a
55 ft mast some years ago in Farnborough due to the 6mm polyprop guys
breaking in a storm. Don't think my neighbour was too impressed about
having the mast, complete with dangly antennas, suspended horizontally
across his garden!
