Thanks for pointing me toward learning about reflection coefficient. I
am really surprised that there is such a large amount of phase shift at that
junction.


W8JI has theorized an even larger phase shift there at the
junction of a loading coil and the stinger of a mobile antenna.
Unfortunately, he attributes 100% of the phase shift below
the stinger to that single junction point, while ignoring
the phase shift provided by the loading coil. This thread
is my attempt at setting the technical record straight and
correcting W8JI's new old wives' tale. This discussion
started years ago on QRZ.com where both sides were wrong
and nobody was 100% technically correct, including myself.
