[SCCC] Retracting towers in high winds

It makes a lot of sense to have a way to retract
a tower to prevent a catastrophic failure of the
TOWER during high winds.
However, that may not prevent the antenna itself from
being destroyed by high winds. In a wind-exposed
place, the winds can be nearly as ferocious 25 feet
above the ground as they are at 70 or 80 feet.
At one time or another, I've lost antennas made by
Cushcraft, Force 12, Hy-Gain, KLM and by me--when they
were on a fully retracted tower. The HF antennas that
survived the longest at my Tehachapi mountain site
were homebrew ones built using construction techniques
described in Dave Leeson's book, "The Physical Design
of Yagi Antennas."
