Hi Bill,

The answer to those problems for me:  Cool Whip.  Well, actually it's 
the container.  I've had coax get caught up in the bolts from the thrust 
bearings, and that caused the coax connector to rip loose  No fun.

I took the container, cut a hole in it the size of the mast, split it 
down the side so it could slip over the mast, put it on top of the tower 
upside down, then used tape to cover the container all the way around.  
That covered up the top of the tower, the thrust bearing bolts, and 
provided a smooth surface for the cables to slide over.

It's been up for 4 years plus after the busted connector issue first 
surfaced - no problem since.  My rotator is a Yaesu G-1000SDX, and it 
has a 450 degree rotation.  No worries after this little mod - and the 
Cool Whip wasn't bad either.

Looking forward to other innovative responses....

Let's hear it for Cool Whip!
