Given that  Steve has maintained that 25G isn't self-supporting at any 
height  literally dozens of times on this reflector, I wonder if that 
document  from 1987 has been superceded.


    Umm, really? Doesn't sound  familiar.
 
    My reference is a little Rohn pamphlet called  "Manufacturer's Technical 
Information for Bracketed or Self Supporting Towers  - 25G, 45G, 55G & SSV". 
Forty-feet of free standing 25G can take 1.5  square feet @ 70 MPH - your basic 
TV antenna. At 30-feet it'll take 1.7 square  feet @ 90 MPH. Surprisingly 
capable. 
 
    I've had this pamphlet for years and don't know  if it's available on the 
website.
