Uh Richard, how does it accomplish that feat without a phase shift?
Aren't -jX and +jX, 180 degrees out of phase? Exactly how is a -jX
offset without a 180 degree phase shift?

In an electrical 1/4WL standing-wave antenna, like an 80m mobile
antenna, the phase shift between the forward wave at the feedpoint and
the incident reflected wave at the feedpoint is obviously 180 degrees.
Exactly how is that accomplished without a phase shift in the loading
coil?

There is a logical intuitive way to arrive at the phase shift through
a loading coil. Would you like to hear about it?
