I have a collinear J pole that I made out of copper pipe. It is
mounted on a galvanized iron coupling at the top of a piece of
galvanized iron pipe. I want keep all parts of the mount at ground
for lightning protection while avoiding corrosion between the two
types of piping. If I use a dielectric union to connect to the
galvanized iron mounting but I still bond both the support pipe and
the antenna base to ground can I avoid the galvanic action that
already caused the two pipe threads to gall.
