  Anyone using the US Tower IV-16 inverted V bracket?  

I have one installed here, and have already seen it spin around approx.  90-120 
degrees  while rotating the antenna stack, and it almost yanked my dipole to 

Has anyone experienced this, and solved it, by using some sort of lubricant 
between the mast and IV mount?   Maybe grease like that which is put into the 
thrust bearing via the fitting? Or some other sort of lubricant? 

Otherwise,    I think I will be lowering the tower and moving the dipole pulley 
off the IV16 and re-attaching it to one of the cross-members of the upper 
section.  I used that method on my last tower for years. Just need an extra 
hand to hold the ropes away from the tower face when raising or lowering the 
tower. But at least you can turn the antenna stack without the fear of tearing 
up the wire antennas.   Then, the next time I bring the tower horizontal, trash 
the darn IV-16.....
