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.
