Alfred --
Copper is next to stainless steel on the galvanic chart, and we use SS
hardware on ali without concern. It would take many years for the
corrosion to insulate the ground plane, and the antenna would still
work almost as well through capacitive coupling. It just couldn't
handle high xmit currents, which ELT's don't have. I see no problem.

keep the joint conductive and prevent corrosion? Any answer is appreciated!
