I am sure there is NO mechanical advantage of dual thimbles over and ceramic
egg insulator.
I my self have never witnessed the dual thimble configuration on and
commercial towers. The one’s with none conductive guys or none conductive
insulator rods all use (Johnny Balls) egg insulators. To terminate to EHS
strand wire .
One other thought as a Belt and Suspender Type … The thought of two metals at
friction points = noise to me…. On one of my towers just the thimbles into the
guy wire flange ( Rohn 65) noise was traced two sources 1 the guy attachment
point and at the Tic Ring rotating ring…. One requires a whisker that rode
along the ring flange as it rotated and all thimble to guy attachment points
had ground brads attached from the guy grips the tower legs…
YMMV

I use guy grips with back-to-back thimbles inside the loops.

There is nothing wrong with using the insulators however I am not sure what
good they do since Phillystran is not conductive. I have been using back to
back thimbles on 6700# and 11200# guys for decades without issue.

this 155ft tower will be Phillystran with a short EHS chunk, about 10-20 feet
long, near the ground where it attaches to the guy anchor plate.
My query is what would be the prudent and safest/strongest method to join that
EHS guy cable to that Philly cable? I have a box full of Rohn 502 insulators
and I was thinking of using those. Any better alternatives?
Thanks! 73 Al N9ISN
