Default Laws, Statisitics, Lies, and the Damned TRUTH

The technical truth will triumph in the end.


As promised, here is a procedure using EZNEC that
will prove just how wrong W7EL and W8JI are about
phase shifts through loading coils.

1. Use the helical coil feature of EZNEC to generate
a 75m Texas Bugcatcher coil.

2. Using EZNEC, find the 1/4WL self-resonant frequency.

3. Load the top of the coil with its characteristic
impedance as indicated by the source's amplitude and
phase being equal to the load's amplitude and phase.
Be patient, because this is an iterative process.

4. Observe the phase shift in the current through the
coil using EZNEC's load's feature.

5. Change the frequency to the user frequency and
observe the new phase shift.
