[TowerTalk] Rohn 25G Guying Height?

[Joe]

My brother has purchased a 50 foot Rohn 25G tower, and needs 
recommendations on guying levels.  I gave him a bunch of Phillystran cable 
and a Rohn 25G anti-torque arm setup sufficient for guying at the 40 foot 
level.  Will that suffice?  He is mounting a 3 element SteppIR at the 
top.  It's been too many years since I had a Rohn 25G.....CRS.

Thanks guys,

73,
Joe
