One amy simply count the rungs on the tower - Rohn 20 rungs are spaced 18"
apart, while Rohn 25 rungs are 15.75" apart.  Use a tape measure when in

A more common error is to confuse Rohn 35 (yeah, 35!) which was special
product for Motorola.  Its 14" faced, while Rohn 25 is 12".  At a fest or
setting in someones backyard, usually escapes detection until attempting to
install accessories like rotor plates, etc.

When in doubt, look at the book (the Rohn Handbook!).
