Medium wave bc stations routinely rely on their radial system for lighting
protection (among other things). A pair of electrodes with a roughly 1/2
inch air gap is a standard component on their towers, one side bonded to the
hot tower; the other on the base which is bonded to 4 to 6 inch wide cu
straps going down the exposed sides of the base pier to the counterpoise
screen and radials.
