“If an elevated installation of a Part 15 AM antenna plus ground lead/ground wire/safety ground or whatever you wish to call it results in operation beyond the limits contained in Part 15, then that isn’t an appropriate place to install it, if your goal is to observe Part 15.”
In this case, beyond the limits contained in Part 15 is only referring to the 3 meter length rule and has no bearing on the range of your signal as range of signal is not defined in Part 15. Of course, when you exceed the 3 meter rule (depending upon how the Field Agent judges your installation), you are no longer operating under 15.219 rather you must comply with the 15.209 field strength.
As pointed out in previous threads on this grounding topic, you can run all the power you want and use the biggest and best antenna you want under 15.209. Just don’t exceed the calculated field strength which of course, most of us can’t measure. Oh, and don’t interfer with any other licensed service.
