Don't you know how to turn on the 'Current Phase' option when
displaying EZNEC results. Do you need a tutorial?

2. -4.91 + -20.59 + -90.01 = -115.51 is different than
90.01 - 15.68 = 74.33

The phase of the source is referenced at zero degrees. The
currents along the antenna are lagging the source current.
-4.91 deg is the phase of the current at the bottom of the
coil. -20.59 deg is the phase of the current at the top of
the coil. -90.01 deg is the phase of the current at the end
of the antenna. Trying to add those phases shows a lot of
ignorance.

3. The coil Vf shown on the web is 0.1375 is different than
eq (32) = 0.0078

Sorry, you're wrong. eq(32) for this coil yields a VF of ~0.033
which Dr. Corum claims to be accurate within about 10%. The
coil VF on the web is at 5.89 MHz, *NOT* at the self-resonant
frequency.

4. refuting your own references (Corum²).

Dr. Corum's equation for the coil VF is at its *SELF-RESONANT*
frequency, not anywhere else. Using it anywhere else is only
a *VERY ROUGH* estimate. At the self resonant frequency reported
by EZNEC, the VF calculates out to be ~0.055.
