Because you're seeing different currents at the two stub terminals, you
must be modeling it with wires, which should reflect reality quite well.
Look carefully at the currents along the stub and you'll find they're
not equal and opposite on the two conductors. Such a radiating stub *is*
very different from a coil.


Instead of a knee-jerk defense of your ideas, why don't you actually take
a look at the problem? Those stubs are vertical. EZNEC shows virtually zero
vertically polarized radiation. According to EZNEC, those stubs are radiating
a negligible amount, just like the lumped inductance. Why the 40% difference
in current between the two configurations? Is this a characteristic of NEC?
