I am living proof of that - my 97' Rohn 25 tower was installed with the
guys at the recommended stations and the guy anchors at the
Rohn-recommended distance from the base. I now really wish that I had
installed my guy anchors another 15 feet or so out, because it would
have given me more wiggle room for my side-mounted tribander, and more
flexibility in where on the tower I mounted it.
