Yes, the ground issue has been discussed at length, but I think it’s worthwhile to continue the conversation. Here’s my take on it.
I don’t think anyone is really denying that the ground wire radiates to some extent. However, 15.219 does not limit the length of the “radiator” — it limits the length of the “ground lead (if used)” plus the other things which are straightforward.
There is science, and then there are regulations. In my real life, I deal with regulators all the time (our state’s Department of Water Resources and Department of Environmental Quality). You quickly learn that actual science is often secondary to the agency’s interpretation of the language of the rules. Everything hinges on the FCC’s interpretation of “ground lead,” not whether the ground lead actually radiates. If someone at the FCC determined that the intent of 15.219 was in fact to limit the total length of radiator to 3m, most elevated installations would be precluded.
