The coil in the EZNEC model on Cecil's web page acts just like we'd
expect an inductor to act. With ground present constituting a C, the
circuit acts like an L network made of lumped L and C which behaves
similarly to a transmission line. With ground, hence external C, absent,
it acts like a lumped L. (There are actually some minor differences, due
to imperfect coupling between turns and to coupling to the finite sized
external circuit.) The combination of L and C "act like" a transmission
line, just like any lumped L and C. And it doesn't care whether the load
is a whip or just lumped components.

But the point is that the delay through the coil is somewhere
between 40 degrees and 60 degrees. When you tried to measure
the phase shift through a coil, you used standing wave current
phase to make the measurement. Standing wave current phase is
unchanging so you made a measurement blunder.
