[TowerTalk] self-supporting rohn 25g??

[K2EK at aol.com]

Probably the most uncomfortable tower experience I ever had was while putting 
up 90 feet of 25G.  

I walked up the first 20 feet and guyed that off.  Then installed the next 10 
feet plus permanent guys.  The WORST part was adding the next 30 feet and 
attaching the 60 foot guys.  The tower was flexing around its 30 foot mid point 
... at 60 feet there was considerable deflection.  Was I ever glad to get the 
second set of guys on?  Doing the 90 foot guys was far less daunting, since the 
lower 60 was far more stable with 2 sets of guys.

I can only think similar thoughts about an unguyed 30 or 40 footer. It will 
surely flop around even with nothing on it.
