Those models also reveal the standing wave nature of the common mode

measurement at a single location to infer any more than the current at
that specific location (if that was important).
In fact, the common-mode currents on the feedline
turn the feedline into a standing-wave antenna.
I suspect that's how an Isotron antenna works.
