Wind is the reason. I get usually two storms in the winter with BIG winds.
My anemometer at about 20 feet has had the cups blown off it with a 116 MPH
reading. Even this military antenna with a 120 MPH survival rating has had
the back two elements tear loose once, and the rear-most element tear loose
twice. The local weather people reported a 136 MPH gust last winter at a
nearby location.

What a shame, sorry to see that. How about one of the SteppIR antennas as a
replacement.

Importance: Low
Aware that the hoisting cable could break, or the winch fail, or some other
unforeseen event could happen, I made sure no people or animals were in the
fall zone.
My expensive mistake was not torqueing the hoist cable's clips tight enough.
The rope didn't break, it slipped through all 4 of the clips, plus the 2
more on a safety tail wrapped around the mast.
I may replace the LP with a conventional 20 m ham Yagi as someone suggested,
or put a nice 10 kW wind turbine on the undamaged mast tube.

I guess you're referring to the photo on http://www.qrz.com/db/w6dsr showing
the damaged log periodic. Many years ago after getting frustrated with
Hy-Gain's toy ham rotators they sent me a commercial catalog. They made
very heavy-duty rotators but I never wound up buying one. It appears that
either your mast became unlatched or it fell during tilting. What a shame!
It looks like you had other mechanical issues even before this. Many of us
including myself have also had expensive antenna failures so don't give up
just because of this. I assume that no one got hurt or killed and hopefully
the towers, rotator and possibly the mast are still OK.
GL!

Hmmm, my VSWR came up a little high this afternoon, see my QRZ page to see

Actually, I shouldn't joke about it - I'm totally devastated.
