[TowerTalk] Use a TRI-EX Base for a US Tower Antenna?

[Mickey Baker]

I have a properly installed RCB-70 base for a Tri-Ex LM-354HD or LM-470
tower. I am going to replace this tower with US Tower HBX-555.

I have engineering documents for a design to remove the "ears" on the
RCB-70 base, drill holes and Strong Tie threaded rod in the base for the
new tower. Simple, effective, should work fine, right?

Looking at the tilt base of the new tower, I see that it may be possible to
fabricate a fixture to affix the new tower to the exisiting base.

Has anyone done something like build a bolt-together fixture, or welded
threaded rod on the TriEx base?

​Should I forget about this and remove the old "ears" and proceed with the
current plan?

Advice is appreciated!
