Phase Shift through a 75m Texas Bugcatcher Coil

information and energy at faster than light speeds?"
Yes, but I don`t necessarily believe them. Wikipedia gives recent
examples of apparent violations of the limit imposed by the speed of
light. However, I infer the editor did not believe them as proving a
violation.
On page 253 of "Transmission Lines, Antennas, and Wave Guides" by King,
Mimno, and Wing:
"This means that the phase velocity vpg is greater in the TM 0,1 mode
than in the TEM type and, therefore, greater than 3x10 to the 8th power
m/sac."
The 3rd edition of "Antennas" by Kraus, et al on page 255 is found Fig.
8-34 showing phase velocity versus helix circumference. Some helices are
shown with phase velocities exceeding the speed of light.
I was one who didn`t believe W8JI`s loading coil instantly induced
energy from one end to the other by magnetic induction.
