Only my observations:
1 - The release cord has withstood Arctic conditions for several years,
without any problems. It shows no sign of weather or UV related
degradation, and works every time.
2 - My weather equipment has recorded numerous 125+ mph gusts from storms
out of the Gulf of Alaska and I've experienced no problems with my Rohn
25/Hazer installation, although the height is "only" 40 feet, with one set
of Philystran guys at the top of the tower.
3 - My Mosley Pro 57B is rises to a height of about 45 feet, with a 5
element Cushcraft 6 meter beam about 10 feet above that.
