A coil inevitably occupies space.

In particular, one of its dimensions is length.

Therefore it can be, and indeed for accurate modelling always should
be, treated as a component having distributed L, C and R.

It just makes the mathematics somewhat more complicated. Hyperbolic
functions can be involved.

Like a transmission line, a coil possesses Zo, phase-shift,
attenuation and Q.

It is why my coil-loaded antenna programs provide answers in the right
ball-park although I havn't a clue about the rules which govern the
American ball game.

By the way, reflections and standing waves are irrelevant and don't
enter the argument. Sorry Cecil!
