inductance to slow down the wave so it gets back in phase.
Exactly. The coil provides a delay and a phase shift. A series
stub will accomplish the same thing. In the middle of an
electrical 1/4WL antenna, any delay through the coil ensures
unequal net current at the bottom and top of the coil even
if the coil is lossless and non-radiating.
