The best method for rotational resistance is to run double guys up to 
your "star" bracket. My 190' Rohn 80 has 2 levels of double guys with 
star brackets and is engineered for four full blown cell sites, (48) 
1-5/8" feedlines, plus 2 full size 40 meter beams.

I can't quite see how a Y in the guy near the top will resist rotation 
very much...
