It could be Rohn 20G or 25G.
Major (noticeable) differences:
20G = 7 horizontal cross members per section
25G = 8 horizontal cross members per section
20G = 1/4" crossmember material
25G = 5/16" crossmember material
There are other differences such as the gauge of the steel in the legs, with
25G having a thicker gauge and hence is heaver. The two dimensions listed
above are the fastest way to check.
Do not dismiss 20G. While it is lighter weight and strength, it is still usable
is one is prudent in the loading. Here in the Midwest 20G is plentiful and
cheap if not free for the taking (down).

Subject: [TowerTalk] Help Identifying tower from photo
Hi Everyone,
Someone sent me a few photos of a tower that they want to sell. However, I'm
having trouble determining what tower it is. My thinking is that it's Rohn 25G
but I'm not very knowledgeable about these. I guess it could be Rohn 6. I put
the photos up on the web in hopes that someone might recognize it. They're not
very helpful photos but some of you eagle-eyed list members might be able to
recognize it from the little information that is in the pics:
