“So in essence the transmitters ground was also a huge circular elevated ground plane consisting of eight 3/4 inch copper cables..
I suppose that is why I was getting a clear strong signal in excess of 5 miles at only 100mw! – It is also probably why I had to send the transmitter back after a few months to have the lighting protection gas tube replaced.. It seems to me that my transmitter did indeed become a lighting rod.
Yes, that would definitely constitute a great ground system, but I think the elevation, considering that the cables ran down outside, constituted multiple radiating elements above ground, like a dipole with an array on the ground side, both horizontal and vertical. I’d say the cables were radiating as much as the whip … perhaps even more. The thing would likely be considered illegal for those reasons.
With those very heavy ground cables, perhaps a lightning strike along with the gas tube break (did its job) went to ground before it fried your TX. Anything less would surely have turned it into burnt offering.
Also, it is in very close proximity to the sea, which can carry a signal quite a ways along the coast line, especially if there are buried power lines along there as well. The ocean is one heckkuva counterpoise, even if not directly connected to the TX.
