Anodize is an insulating surface coating. Take it from there on what that
means to joing the elements of an array electrically.JIM W4QBQ

That's not true at all. Anodizing merely adds a dye to a very thin
surface oxide. Aluminum oxide is going to grow naturally anyway, and
is essentially an insulator. Skin effect doesn't apply to a surface
insulator.
