One ground rod does not a lightning ground make.
For best results, the rod(s) should be completely below grade.
Usually a ground will last for about a decade or so. Where do you
live? The choice of grounding material is determined by the pH of
your soil. An acidic soil (normally found in the eastern part of this
country) would kill copper. Galvanized, tinned (copper) and aluminum
based materials would last longer. Alkaloid soil (normally found in the
western states) would zap the aforementioned material and copper based
would be the way to go.

Subject: RE: [TowerTalk] Are "Ufer" grounding BEF
Well my two cents on this subject is this. I decided to drive three
ground rods at the bottom of my cement base to hold and align the tower
mounting base in the concrete before pouring. I know having ground rods
protruding out of the cement is supposed to be a no no because of
corrosion. I figured it this way if it takes twenty years for the rods to
corrode away the base I'll be 76 years old and probably not living at
this house any way. Who ever is there will be cussing at me trying to
figure how to cover up that 5x5x5 cube of concrete. In the mean time if
lighting strikes it can go right into the ground through the base as well
as my other six rods on the outside of the base.
