Cecil,

I was going to drop this discussion, but I will respond to your request
to share physics knowledge.

1) I will repeat. E-fields, H-fields, voltages, and currents are all
related through some very profound equations. However, shout THEY ARE
NOT INTERCHANGEABLE. /shout

This is not just a matter of semantics. These entities have different
physical meanings, different units, and different dimensionalities.

2) I offered a physics-based explanation for your proposed "current
drop" in the 440 MHz RG-58 example a few days ago. Did you not read that
message before responding to it?

3) A one foot long section of wire and a one foot long section of coil
exhibit similar phase shifts, according to both the theory and the
reported data. What is not correct is the assertion that the coil
exhibits a phase shift consistent with, for example, 20 feet of wire
used to make the coil. The notion that a coil replaces some sizable
portion of the total phase shift in an antenna has been shown to be
incorrect. Experiments reported by Roy and Tom R. convincingly
demonstrate the phase shift behavior of coils.

Please pick one item of physics with which you disagree with me and let's
discuss it in a gentlemanly fashion. There's some pretty savvy people on
this newsgroup who agree with me. Perhaps, the argument is only a semantics
problem, like the definition of "drop" and "flow". It's really hard to see
how an E-field can drop but not flow and an H-field can flow but not drop.

Pick one simple topic upon which you think you and I disagree. So far,
you have posted nothing except ad hominem attacks. That's not a good
way to impress people and win technical arguments. I think you are a
better person than that.

Here's a topic if you can't think of one. How can a one foot long section
of transmission line exhibit a phase shift if a one foot long coil doesn't?
