Thanks to all who have tried to help me identify this old tower. The tower is
a 3 section crank up. Each section is 20' long. The top section is rather
narrow and my Ham4 rotor is about a 1/4 inch to big to fit inside. Can just
barely get the slightly smaller Yaesu rotor in.
Measuring the verticals on the top section, it is about 7 3/4" center to
center. The bottom section is about 11 3/4" center to center. The vertical
tubing is 1.01" od. and the wall thickness is 0.070".
I did contact Rohn about the possibility of it being a Spaulding and was told
rather bluntly it is an old obsolete tower and they do not have any information
available.
