[TowerTalk] HDBX Version History...

[Kim Elmore]

Ah, yes! I now recall that I used to know this. Maybe what he had was a 
Spaulding version? But it definitely had the swaged, stepped-in taper, 
instead of a continuous taper like Delhi. Maybe it was a Spaulding? A 
little bot of Google-fu turned up that when Rohn bought Spaulding, they 
changed the design quite a bit and used heavier gauge steel. From what I 
read, the Spaulding and Rohn BX series are similar in name only -- no 
parts are interchangeable. Still, the Rohn documentation says no booms 
longer than 10'. I have to wonder of that's simply a holdover form the 
Spaulding rating or of Rohn re-engineered all the ratings?
