No need to do anything, functionally.
If you want to keep it with a shiny clean copper look, some have good results,
by wiping with a rag saturated with dow corning silicone grease from time to
time.
We took a tour of transmitter site of KGO, a textbook perfect, to die for, MW
TX/Antenna site. 810 AM 50 KW on the extra salty south end of SF bay. 3 x 1/4
wave phased verts shown in pictures below:
Some photos show clearly the 2" copper strap running down from the antenna
ground/common point to the salt water at the base of the concrete pedestal.
I looked at them closely and the 2" strap went to a star junction of many
radial 2" straps that were submerged slightly below the water level at the
tower bases. Seemed to go out only about 20'radius in the water, completely
submerged.
It had a brown overalll patina, with a lot of green copper oxide crud in
various places. Seems to not rot out, even for years as a 50KW AM ground
strap.
