Here's an interesting EZNEC result. I took the 102' loaded dipole
that was resonant on 3.76 MHz and ran it on 14.3 MHz. I repositioned
the loading coils at a current minimum point with a one ohm resistor
on each side so there is 0.03 wavelength between resistors.

--------------R1--coil1--R2-------FP--------R3--coil2--R4--------------

EZNEC sez:
Current through R1 is 0.1618 amps at -156 degrees
Current through coil1 0.09643 amps at -130 degrees
Current through R2 is 0.08098 amps at -70 degrees

In the ten degrees between R1 and R2, the current doubles and shifts
phase by 86 degrees. Can we use these results to prove there is a
phase shift through a lumped inductor? :-)


No.

It'll take a lot more than an EZNEC analysis, or back yard measurement
for that matter, to disprove theory that's been verified and used
successfully for more than a century.
