[TowerTalk] torque arms or not?

The guy bracket on larger towers is u-bolted to the tower leg and bracing,
it does not encircle the tower. It is not necessary to encircle the tower.
My Rohn guy brackets look like this

Although it's a common practice with hams, Guys should be attached to a
bracket, not individual tower legs. It's not normally a problem, but guy
brackets like ROHN sells puts no strain on an individual tower leg. On a
heavily loaded tower,(near its wind load limit), when the guys are
attached to individual tower legs, in high winds, the tower leg on the
windward side takes the strain. With a guy bracket encircles the tower
with the guy strain taken by the bracket and converted to a downward
force, putting far less strain on the tower.

You don't see commercial towers with the guy wrapped around a leg.
