[TowerTalk] Mast slipping

[Rich Hallman - N7TR]

I modified mine with the hy-gain clamp.   Been up for many years and major winds with no problem.  I think those cast clamps are pretty cheap from MFJ now.

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.
