There are base loading coils in shielded boxes which don`t radiate but
do have significant inductance which make too-short antennas seem long
enough for impedance matching purposes.
But the point is, those loading coils in shielded boxes are NOT *lumped
inductors*. We have been told that lumped inductors have zero phase shift.
Apparently, a 45-degree phase shift in the current through a lumped inductor
would violate the rules of usage for lumped inductors.
I have no doubt that real-world inductors provide a phase shift in the
current. My statement was limited entirely to lumped inductors, a purely
imaginary conceptual model. Sorry if that wasn't clear.
