ARGH! another thread that will never die... time to 'ignore' this one also.
don't you guys realize you will never agree on anything on here? you talk
in circles around and around the same dogmatic circles never seeing that you
are all saying the same thing in different terms and arguing around nits
that don't matter in the real world.

I think that's the point. Cecil and his buds are doing this for
entertainment.

:-) Gee, I think Cecil is trying to carry this one by himself. I
don't see any of "his buds" on the list of contributors. Certainly
Tom, Ian, Roy and I are in very close agreement about this topic.

It is worth a step back from all this, though. If the lurkers can get
the single idea that it's the _current_ distribution on an antenna
structure that ultimately matters, not any voltages (whether we can
agree about them or not), then they'll have gained something of value.

If they also pick up some simple things like "electric fields are
always very nearly perpendicular to the surface of good conductors"
and "the potential between two points in general depends on the path
you take," that would be a nice plus. If they get curious and go
learn more about those things, that would be wonderful.

Cheers,
Tom

I agree that *measuring* the voltage is a challenge.

It's hard to develop that H-field without an E-field. The feedpoint
impedance of a standing wave antenna gives a deductive clue to the
magnitude of the E-field and it is not the same as a traveling wave
antenna. It also varies up and down the standing wave antenna.
