[TowerTalk] Rohn 25G Tower

[kb0fhp at comcast.net]

Follow the manufacturers instructions, and unguyed RG25 is acceptable.  Obviously, free standing to 70+ feet does not meet the manufacturers recommendation.  Rohn 25G can be self supporting per the manufacturers instructions.  It can also be bracketed per the manufacturers instructions.  It can also be guyed per the manufacturers instructions.  You can just go higher with guying, and support a greater windload.    For some of us, bracketed and going to 35-40' is a good compromise between having something in the air, and not having something in the air.
