You make a good point. I would suggest, however, that a single ground rod is
probably inferior to the system you describe. Also, the typical broadcast
station uses AWG 10 for the radial system. That's a far cry from 0000 !
In any event, the station that I was referring to was located in a swampy area.
Radials alone may work in some circumstances, but I like what the tower
manufacturers and the NEC have to say on the matter...a solid connection to
ground rods is a good idea!

Hi
I worked at a college FM station where the idea was that a simple rod in the
ground
would be the only grounding. First storm, and the remote was taken out. With
much
effort, the chief tech convinced the higer ups that a radial system made up
of 8
80 foot 0000 copper cables would work as most lightning strikes from the
ground
up. The system was installed, and lightning bolts smacked the tower with
glee.
The transmitter stayed on the air, The system is still working 30 years
later.
