    Rohn 20G and 25G are practically identical with  Z-bracing. The only 
difference is that 25 has 8 horizontals and 20 only has 7.  With less bracing, the 
20G has less torque resistance and is specified by Rohn  for only 
TV-antenna-type applications. Here's what Rohn says about it:
 
    "The #20 tower  is not recommended for commercial, ham, CB or guyed  
installations."
    
    I think what the tower of interest is is like  Rohn 6 that has no 
diagonal braces - only horizontals. It is another type of  TV tower and was made by 
many manufacturers in the days before cable or  satellite TV signal delivery. 
There are thousands of 40-footers still up in  the mid-west and around the 
country with TV antennas on them. That's why  they're cheap and plentiful.
