Dave:

An exposed copper to galvanized steel connection will quickly lose the zinc,
and the steel will rust profusely. So, whatever approach you use, put lots
of weatherproofing over the joint. Personally, I use thin stainless steel
between the two dissimilar metals along with Penetrox and then weatherproof
with roofing tar. The professionals use a special crimp connector or a
purpose designed CadWeld connection.

The answer must be here but after some searching I can't find it.
There is all sorts of conversation about ground rods and dissimilar
metals but I can't find the basic answer I need -- How do you make the
steel to copper connection? Do you simply clamp galvanized steel to
copper? Thanks.

Same approach here, without the tar. On my Rohn 45 I replaced the
smaller bolts at the bottom with stainless and used double
nuts/washers to attach the copper ground wiring. Of course, it seldom
rains here and the low humidity helps in the corrosion department.

Purists will refer to the galvanic tables and go from there, but this
works for me.

Maybe Barry Ornitz will answer this for you. If not Google him.

I think Barry got fed up reading some of this junk. I haven't seen a post
from him in quite a long time.

Me neither. I think you're probably correct.
