Everitt, then the Dean of the EE Dept at Ohio State U. Everitt was doing the
grunt work and taking measurements along with another OSU professor. However.
Loren Windom was a student of Everitt's, and was tagging along and observing.
Then, later on he wrote up the experiment and had it published in QST sometime
in 1929, and as well as I can remember, he failed to give Everitt any credit for
having done the actual work. Consequently, readers of QST assumed it was
Windom's invention, while it actually was not.

Walter:

Thank you for that clarification, it was also interesting and
enlightening--I was ignorant to that info.

Warm regards,

Hi John, glad I could make that microcontribution.

Now I realize that some of you are non-believers, so for you this is an
exercise.

It's would be pretty arrogant to consider that you have the ability to screw
up God's plan. We can't even be sure that Satan screwed up God's plan, but
it appears that there is some contention that is/was/does exist in the
heavenly realm.

Now consider that he allowed your being to come into existence perhaps for a
purpose. OK that is implied in scripture.

Now consider that you don't know what your future is even if God
pre-ordained it. If you did, what good would it do you and wouldn't that
influence your choices? Only Jesus was in on His future from the beginning
and knew how his life would play out and even tipped off the Disciples piece
by piece throughout his ministry. Even told them in real time what was
happening as it happened and how it was foretold in earlier scriptures by
the profits. This shows him to be familiar with numerous events in time and
how they play out together and the significance. It has been postulated in
a regular radio series that the Bible is a sophisticated messaging system
outside of our time domain planted by God to relay information about our
past present and future to future generations.

Now consider that Moses negotiated with God over who would do the talking to
Pharaoh and God relented and let Arron do the talking while Moses did the
signs. But God revealed to Moses how Pharaoh would respond and how the
whole scene would play out. That's a real mind blower. This shows that
some could actually have been doomed while some obstinate and sinful people
could still negotiate some things with God and even make bad choices,
although risking serious consequences for some of those choices.

So were left with this:

God's plan won't be usurped, but we can petition Him with prayer over some
points. This leads us to another possible conclusion.

Perhaps there are parts of his plan designed to allow for us to make a
variety of choices despite his intention for us. So you DO have free will
even if he already knows how you will choose. It has been stated by Jesus
that He came so that none should perish but all could come to repentance,
have life everlasting, have life abundantly and other statements to that
effect given the shortcomings of language. This implies that we really DO
have choices even though it doesn't quite make sense unless Jesus really did
make a change where someone like Moses' Pharaoh could now have a choice. It
also allows the possibility that if one missed an opportunity, there could
be an infinite number of others that do his will anyway.

I don't like to delve too deep into this because there is a lot to learn bit
by bit and we run risks by jumping to conclusions beyond our understanding.
I merely note some interesting points from Genesis, Exodus, Matthew, Mark,
Luke, John. I'm not much for citation of scripture and verse because I
believe context is far more important than throwing one liners at people.

deals with a Windom Antenna, his text on the design, construction,
function and implementation of baluns is well worth the read.

Doesn't that article espouse the Guanella 4:1 current balun built on a
single toroid?

The extent to which such a construction works is due to flux leakage,
rather than the principles described by Guanella.

Yes and I have to partially take back what I said; a balun CAN double
as a CM "choke" and a CM choke can double as a balun. If
one wishes to balance an unbalanced line with a CM choke, then the
impedance of the CM choke must match the source and the load, which
makes the CM choke a balun and no longer a choke :-)

Actually, a balun without a large choking impedance
is not very useful for ham antenna system applications.
The method that a W2DU balun uses to balance currents
at a dipole feedpoint *IS* nothing more than a large
choking impedance which discourages common-mode current
from flowing through the higher-the-better impedance.
I usually refer to the W2DU balun as a choke-balun.

Actually, 1000 ohms is pretty liberal. For instance, on
15m, the G5RV coax sees 36+j230 ohms or about 233 ohms.
The balun needs to be 10x that value or 2330 ohms.

Why not 500 ohms, assuming a 50 ohm source and transmission line?

Be the current making a choice of paths at a junction.
How much of you would flow through 500 ohms and how much
would flow through 233 ohms? (If 500 ohms is the total
impedance seen by the shield current looking back toward
the source, about 1/3 of the current would flow back
through the 500 ohms down the coax.)
