[TowerTalk] Help Identifying tower from photo

[Wayne Kline]

>From the pictures supplied. I venture to guess it's Rohn 25.  Rohn 20 will physically interchange with Rohn 25 but it's significantly different in lighter gage material and lattice design.
Rohn 25 legs are 1.250 od 16GA  and 20 is 1.250 18 GA. the lattice material on 25 is 5/16 solid rod and 20 is 9/32 and the biggest visual difference is Rohn 25 has 15 3/4 between horizontal cross braces as compared to Rohn 20's  18 1/4 distance. resulting in 8 cross braces per 10' foot straight section of #25 and only 7 on #20.
