Well. What I'm learning is that not all HDBX48s are the same, so unless I'm told the lineage of what the picture showed, I have no idea. It was a long time ago, and mine has certainly weathered some

Yes, from what I understand now, you are correct. According to some info in found in some archives, Rohn redesigned the AX, creating the BX (B-model using X bracing, I guess). Not only did they add a

I think we're referring to the difference between the AX (Spaulding) and BX (Rohn's redesign of the AX) tower sections. The difference between the BX, HBX, and HDBX is in the sections used. The talle
