[TowerTalk] Ground strap to water pipe?

[Martin, AA6E]

Wisdom, please:  I want to run 1.5 inch copper strap from my SPG
bulkhead to my AC ground point, which is my water service entrance,
following the "bond the grounds together" principle.

Question is what is the best way to transition from the copper strap
to the water pipe, which is maybe 1.5 or 2 inches in diameter? (Don't
know for sure because it's really hard to access in my crawlspace.)

I don't find any commercial products for this scenario.  I could rig
something with U bolts or radiator clamps, but what is the group think
here?  Is there a problem with copper to steel contacts?  Do we
believe in special ointments like "kopper shield"? Etc.

Thanks for your attention.
