Not cheap, but can work for your idea is the GS-050
if the cost is your problem , need to copy that idea and go from there to your
own solution
for a LONG TERM installation
SHORT TERM some Lithium Grease and short pieces of 1/8 steel cable from the
original plate to your rope, but not always works perfect and will damage the
galvanized pipe
If i have that need will install 2 or 3 sections of tower (small) or aluminum
, double plate and the the rotating pipe seated on one thrust bearing TB-3
or similar, above with one GS-050 yaesu thrust bearing and some philly 1200
but My case and my solution , maybe gives you another point of view

I'd like to rotate a 45' pushup mast (a Rohn H50) from the base. What sort
of guy rings exist that will slip smoothly to avoid winding up the guys?
I'd also like to use Dacron rope for the guys, but I'm concerned about
abrasion or cutting where the guy attaches to the ring. Are thimbles
necessary? The existing guy rings appear to have awfully small holes for
thimbles.
