Guess that "477 ohms" proves it. :-)


Your point being well taken, I can only reply, "477 ohms can ONLY be as
important as the equations which depend upon it to function."


Dang John, you missed the point. In the free space
that exists in my universe in Texas that figure is
376.73031346177... ohms.

Is 477 ohms the Z0 of free space in the land of
fruits and nuts? :-)

John,
my first point was the 477 error but you didn't catch on.No problem
...

My very best regards
Art Unwin KB9MZ.......xg


Yes, both you and Cecil were kind enough to point it out ... hey, what
can I say? I was an idiot and slow on the uptake. I will attempt to be
more observant, but hey, I make such mistakes, now and then ...

Not 477 ohms but 377 ohms, not 477 ohms but 377 ohms ... now, writing
that another 98 times and I may have it! :-)

JS

You and Cecil, both, have my location in error ... I DON'T live in the
Gay Bay! (i.e., San Francisco) :-)

Personally, I am attempting to get my representatives to sponsor a bill
to give every documented gay person $100,000 to move to Texas!!!! evil

"With inter coupling of elments you only get approximations as the last
element of any array radiates half of that which it receives."

That might be true if the final element in the array is exactly matched
to a load. If the element is lossless and perfectly mismatched, i.e. its
load is a short-circuit, 100% of its received energy can be reradiated.

I choose to respond to Art on this thread and not to start another to
contradict his prior art.

Yep, when I lived there, the characteristic impedance
of free space was still 377 ohms. :-)

The climate in Texas is not very good for gays. Texas
is the only state that still has the legal right to
secede from the Union. Don't be surprised if it happens
under Obama's "rule". One of his transition staff actually
asserted that he would be "READY TO *RULE* FROM DAY ONE".

Don't think that you will be alone. Although, "they" attempt to paint
my state as a bunch of gay-pinko-commies, some of us don't think so ...

However, given the "last eight" and the party which got us here, I am
willing to see what happens first (Bush NEVER lifted a finger to repair
the criminal actions of Clinton--NAFTA is only one example.) And, IMHO,
printing 850 billion dollars and giving it away to those using practices
which got us here in the first place is NO ANSWER ... I'd say the fox
already runs the hen-house.

Keep your finger on the trigger, but don't fire until you see the whites
of their eyes ... :-)

JS

Texans are too chicken to secede from anything, but it's a nice thought.
If Texas were to secede, the rest of us could say, (stealing from Dr.
Martin Luther King) "Free! Free, at last!"

I am aware of that. One person once said the world was round!


Actually most learned people knew the world was round since before
Christ. The circumference was measured to something better than 10%
accuracy using only sticks and shadows.


If one was persuasive enough at the beginninghundred years or so later
if one said
the world was flat he would be called delusional.
If one was very persuasive in the first place he would be rediculed as
it was so obvious to all in the first place.
I hope you get to live another hundred years so that you can meld into
the new crowd of lemmings

Art


And delusional you are. No doubt about it.

Actually, "sticks and shadows" is nice, for emphasis ... "wells and
shadows" would be a bit more accurate:
