[TowerTalk] SPG Panels/feedthroughs etc

[charlie at thegallos.com]

We all know that the classic ground panel is a plate of copper of some
thickness, and also that other than silver, Cu is the best conductor out
there

My question - I am thinking of making a ground panel/passthrough
(combined), and I was wondering how well Aluminum would work.

Yes, I realize it is NOT as good a conductor (duh), but is it "good
enough".  I have access to enough 6061 sheet/plate to make what I need, so
the real question is "when is good enough, good enough"
