Steve, Load the dissimilar-metal connections up with conductive grease -- Noalox is one brand, and ICE makes several types, too. Check them once a year (more often if you live in a harsh climate, like a maritime area or alkaline desert), and renew the coating. I use conductive grease everywhere I have metal to metal connections, but especially on grounds. It's especially important where you connect copper to galvanized steel, such as tower legs or guy wires. 73, Tom, KT9OM At 12:28 PM 10/10/03 , you wrote: >Thanks for your indulgence.
