[TowerTalk] Mast slipping

[Dino Darling]

You see this a lot with chrome moly masts.

I highly recommend the use of DX Engineering clamps in place of almost
any other clamp! The increased surface area of the clamp works great!

You can always try the Slipp Nott too...

I just got down from my tower after turning my XM-240 in line to match
the rotor and other antenna AGAIN.
I have done this several times now and I just can't get a grip on why
this continues to happen. I haven't had trouble with any other of my
antennas,some have more windload than the XM-240.
As I was up there enjoying the view and thinking why this one turns I
had an idea and wanted to ask others ideas.
First it is up 85 feet and has been up for 6 years and I think it works
great. It is much more stout than the 40-2CD that I had up before but
came down piece by piece in a bad windstorm.
I am using the stock clamp which seems to be great,the only thing that I
haven't used one other antennas but did on this one was a galvanized
mast from Texas Towers. Could it be that the mast is too "smooth" to
grip? The U-bolts are not loose when I go up to straighten the antenna.
It only happens once a year or so nd always after a 70-80 MPH windstorm
which we get here sometimes. 
Looking for ideas.
