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

[Edwin Karl]

I'm not sure I would trust tied all thread solely in a situation like this.

Better drill holes, use galvanized iron rods and epoxy to connect to the 
base.
Use the regular base for the tower, with the rods holding in place. Have 
you checked
the overturn moment one to the other?
Is the base reinforced?

Good luck, we're all counting on you ...!
