no, it doesn't eliminate RF, it just equalizes the voltage between the
ground and the fence. This prevents what power utilities call 'step' or
'touch' potential. by making the voltages the same someone standing on the
ground then touching the fence won't feel anything, the same if they
happened to touch the ground screen and a nearby fence.
