[TowerTalk] EHS cable and torque bars

[Mike H]

I acquired some used Rohn 45G in very good shape and will be going up 50 
ft. Antenna will be stacked 2 x 9-el for 2m. I'm following the Rohn 
engineering guidance very closely: base is a new R-SB45G buried in the 
prescribed concrete block along with GAR30 guy anchors, also in 
concrete. I have the older style guy bracket for 45G that has (very 
expensive!) TB45D torque bars

along with several hundred feet of brand-new 1/4 in EHS for the guys. 
According to the Rohn instructions, however, I can't use EHS cable 
that's greater than 3/16 in:

This means I'd have to buy either smaller EHS cable or their newer guy 
bracket that doesn't use torque bars. I'll do this if I have to, but I'd 
sure like to understand why 1/4 in EHS is a deal-breaker for the torque 
bars. QTH is north Florida so I want to make the setup as storm-proof as 
practical. Any insight appreciated.
