I've been following this thread and most of the  answers you got were either 
flat wrong or based on some anecdotal info that  clearly exceeds the 
manufacturer's specs. And the examples you cited above are  downright DANGEROUS. 
What're you NUTS or something for climbing them?!?
 
    There is a pamphlet and the info is also in the  Rohn catalog. For the 
most part, you can go 14 feet above a housebracket but  freestanding specs 
depend on the load and the windspeed.
 
    You can get a Rohn catalog on CD - a highly  recommended addition to your 
tower library - from _www.rohnnet.com_ (http://www.rohnnet.com) .  They'll 
send it to  you for free.
    
    The same info is on the website and you can look  it up. 
 
    The bottom line is that freestanding Rohn 25g,  etc. are rated a LOT LESS 
than you think. And ALWAYS follow the LXC Prime  Directive to "DO what the 
manufacturer says".
