[TowerTalk] alternative to concrete stubs for Trylon tower

[Rob Katz]

I have a Trylon 72' tower that I'm installing this summer, and I have 
the "base foot weldments" (these are feet that bolt to the bottom 
tower section and then bolt to rod that is sunk in the ground). 
While these feet are usually used to anchor into rock, can they be 
used with a concrete foundation?  If they can, then I have some 
questions about using them.

Would it work to encase the anchor bolts in the foundation when it is 
poured, or do I need to drill holes into solid concrete and epoxy in 
the bolts?  If I put the rod in when the concrete is poured, do I 
need to have anything attached to the rod at the bottom to add 
resistance to being pulled out?

What kind of rod should I use - all-thread or something else?  It 
looks like they need to be 4-5' long, and I assume they should be 
galvanized rod, yes?

Finally, where would I find such bolts?  What kind of industry or 
distributor might have them locally?

Thanks in advance and 73,
    Rob, KA1ARB
