Default Current through coils

Your professor would have told you that you "overlooked" the phase shift
in the voltage.

Does this mean: "HERE WE GO AGAIN"?

I was taught that there is a 90 degree phase shift in an inductor. But,
in a loading coil there must be less than 90 degree phase shift because
the top portion of the antenna still has a small, ~3 to 5 degree, phase
shift required to achieve resonance. So, does the inductance have a 90
degree phase shift or an approximate 85+ degree phase shift.

Voltage and current are in phase at the base and 90 degrees out of phase
at the tip, at resonance, conclusion: less than 90 degree phase shift in
the inductor. PLEASE EXPLAIN this physics anomaly!
