Default Current across the antenna loading coil - from scratch

If the voltage is leading the current, and the current
experiences no phase shift through the coil, doesn't that
imply that the voltage must travel faster than light and
indeed jump forward in time to catch up with the phase
of the current?

What does it mean to the E-fields and H-fields to say
the voltage is leading the current?


It means that the current at both ends of the coil was delayed
(relative to its phase if the coil had not been there). It means that
there was a voltage difference across the ends of the coil that drove
that current through the coil.
