Default Current across the antenna loading coil - from scratch

Funny, that's just the way most of your postings appear to me and, I'm
sure, to Tom.


Then there is your answer to who is "gurus" and who is "we".
"Gurus" know that current in loading coil is the same.
"We" know, measured it properly and argue that that is significantly
different.
I am sorry, you are wrong. I tried to follow some stepts to get to the
point, Tom ignores my points and jumps to lecture how, bla, bla...

I am really done here, you guys can believe what you want. Just that reality
doesn't jive with your "can't be".

yep, "hope" with pictures, measurements and descriptions (no good)
vs. "experience" = it can't be, but, but, but... ("proof")
how does the coil have higher current at the top if it loses radiation
through capacitance to W8JI? "Experienced" silencio!!! There is your sign!

Richard, keep up sticking needles, that really sheds light on the subject

Happy Easter to everyone, even unbelievers!

Hi Yuri,

I was at Seder last night. Are you calling me an unbeliever?

Unfortunately Richard, to many, including some I am acquainted with, you
would be considered much worse than that. Minnesota is not as broad
minded as they like to pretend. Religious hangings weren't that long
ago here.

And, as the grandson of Polish Jews who, for some unknown reason, hid
their ancestry to the point where I was raised Catholic, I am obviously
conflicted!

(Continuing the basenote drift, since the basenote thread is pretty
much a mess anyway...)

So it's not clear to me who might be calling whom an unbeliever. Both
Christians and Jews celebrate seder. Maybe it would be those of some
other faith? It's interesting to me--and sad--that so many whose
religion teaches that God is all-powerful and too great to be known
fully by any person are intolerant of others whose religions teach just
the same thing. The intolerance seems as common between sects of
nominally the same religion as between religions. If you can't ever
fully know your god, who are you to say it's not the same god as the
one someone else worships differently, or as someone else worships as a
set of gods?

Hey, we might as well be discussing religion as loading coils...

Ducking,
Tom

Wot's seder?

Can one drink wine to excess?

If so, can I join the club?

No, it's just that certain groups of Xians, not a majority but getting
too populous for my taste, seem to think they are the be all end all,
and everyone else is going to HELL, even other Xians, especially
Catholics. And those that aren't Xian, fuggetaboutit, they are all
damned even if they are Good Samaritans and kinder than Mother Theresa,
because they don't belive in the RIGHT THINGS.

I would hope not!!

Here in NH the Jewish community invites the Christian, including
Catholic, Community to share the SEDER with them. The SEDER is served in
the meeting room at the local synagogue. About 200 non Jewish people,
meaning Christian, from the City of Manchester attend. It is an annual
event.

The Jewish Community is REFORMED. I do not imagine such an invitation
would occur from an Orthodox or Conservative Community. I respect their
practice.

In the recent past I have been invited to pray in the congregation with
a Conservative Community in Massachusetts. I am humbled. The Rabbi is a
holy man.

Hi Yuri,

Yesterday I posted in this thread a very simple ideal lumped-circuit
specific example of how it happens. Have a look for that. Consider
the capacitance in that lumped circuit to be part and parcel of the
coil in the distributed case, so you can't in the distributed case
separate its current from the coil current; all you see is the current
going in the "input" terminal (1.3 amps, per Cec's request) and the
current coming out the "output" terminal (2.1 amps) into a load
impedance. If you don't overconstrain the problem (that is, if you
don't specify anything beyond reasonable input and output currents and
load impedance) I can show you a lumped circuit with only series
inductance, series resistance to represent loss if you wish, and shunt
capacitance, that will do the same thing with respect to terminal
currents.

It really is not a stretch at all to get more current coming out than
going in. It WOULD be a stretch to have more power dissipated in the
load than you put in the network, but that's not what's happening, of
course.

Is that all specific enough for you, or would you like to give me a
challenge with a different set of input and output currents and load
impedance (which agrees with what you might actually observe in an
antenna-with-loading-coil situation, and not some ridiculous impossible
set)? I'll even embed the capacitance in the circuit so you won't be
able to say you could measure its current separately from that of the
coil. It's a somewhat pointless exercise, but good mental stimulation,
like working a crossword puzzle, so I'm up for it.

(I trust you didn't really mean that the coil loses radiation
_directly_ to W8JI in your posting quoted above! If every loading coil
in the world did that, poor Tom would be getting pretty warm, I
suppose. In any event, PLEASE UNDERSTAND THIS: the displacement
current from the coil is mostly NOT losing power to the outside world.
Like current in more tangible capacitors, it represents stored energy
that's put into an electric field in part of the cycle, only to be
almost all returned in another part.)

Cheers,
Tom
