Greetings Tower Sages... I had one of these on the top guy set of my 110' R45 tower. And I had torque arms on the lower two guy sets. My question is aside from twisting, does this change any of the w

Since the capacity of a tower is determined by the leg strength, I'd say that the use of a star guy bracket doesn't really do anything to change it. I'm not an engineer so I don't have any calcs
The use of star guys reduces the wind induced torque on the tower by reducing the amount of twisting in the winds. This reduces the twisting and stress experienced by the legs of the tower. There are

I would not put more on a tower than Rohn's wind load ratings allow just because a torque guy is used. A 6 way star guy does a great job of minimizing twisting. There is more leg compression since th
Hello all, Couple of comments on K4JA's tower failure. The lower half of the tower was shielded from some of the wind by way of tall trees at the edge of the field, where the woods started. The uppe
All great points. A tall skinny tower with slip rings, with many large antennas, in a high wind area, is a temporary setup IMO. -Steve K8LX Hello all, Couple of comments on K4JA's tower failure. The

That is my concern too with rotating towers however there are many out there. John KK9A A tall skinny tower with slip rings, with many large antennas, in a high wind area, is a temporary setup IMO. -
Guys, Another thing that might make your skin 'crawl' is the way Paul's towers were guyed. I believe his brother, an ME, designed all of his rotating stuff. At each guy ring, the contact points wit

All yagis should definitely be torque balanced, preferably right at the clamp where it bolts to the mast. Having said that, a significant issue is that local topography and wx cndx can combine to ins
