Default Phase Shift through a 75m Texas Bugcatcher Coil

Not disagreeing in general but just fine tuning a bit.
In an HF mobile loading coil, the EM waves are photonic
in nature so a few photons are capable of migrating to
adjacent turns - certainly not enough to cause the 3
nS delay through a 10 inch long 100 turn coil reported
by w8ji, but the effect is enough to roughly cut in half
the time taken for the current to negotiate the coil wire.

Cecil:

What would you offer as to the "photonic-jump", the capacitance of the
adjacent turns with air serving as the dielectric?


Since inductance lags and capacitance leads, wouldn't the inductance
value between turns serve to offset this? And, the diameter of the wire
become a major factor in the phenomenon you propose?

What if a spiral wound faraday shield is placed between the turns?
Would we still see this "photonic-jump?"
