That's not a ground system, it's a dummy load. A ground system requires
either radials or a counterpoise of the sort that K2AV has developed. A
radial system has two functions -- to SHIELD the antenna's fields from
the lossy earth, and to carry return current. All the ground rod does is
connect to lossy earth, which, as far as the antenna is concerned, is a
big resistor.
