We know that a loop antenna is good for mag fields and a diploe
is good for E fields. But since the E field is (120 pie) times
stronger than the mag field, why is there any consdieration to
using a loop antenna?
This question has gnawed at me since my EE course work, but
nobody seems to have a situation where the mag field is better
to receive.

TIA,

First, a loop isn't "good for mag fields" any more than a dipole, and a
dipole isn't any more "good for E fields" than a loop. See my posting of
about 3 days ago in this newsgroup in the thread " Loop vx Folded
Dipole noise factor".

Second, the E field isn't 120 * pi stronger than the H field. In free
space, in the far field from the source, the E field is 120 * pi OHMS
times the H field. You could say one is stronger than the other only if
they had the same units, which they don't. A parallel to this would be
to say that the voltage is "stronger" than the current in a 10 ohm
resistor, but "weaker" in a 0.1 ohm resistor. Voltage and current are
different things, just as E and H fields are, so can't be directly
compared for "strength".

You might want to dust off the fields text you used in your EE
curriculum, and review the relationship between E and H fields, and what
happens when they interact with an antenna.

There is only one Field which has components.

Most likely, the source of such widespread defective reasoning lies in the
curriculum.

It's the same with SWR meters and PA conjugate matches. ;o)

Your signal and my signal are components of the same field?
Talk about unified field theory ... :-) Happy Holidays, Reg.

And a Happy Holidays wish for everyone.

Stuffed Cabbage Rolls

Babies really can be found under a cabbage leaf -
or one can arrange for ground beef to be found there instead.

8 large cabbage leaves
1 lb. lean ground newborn human filets, or ground chuck
Onions
peppers
celery
garlic
soy sauce
salt pepper, etc
Olive oil
breadcrumbs
Tomato Gravy (see index)

Boil the cabbage leaves for 2 minutes to soften.
In skillet, brown the meat in a little olive oil,
then add onions, peppers, and celery (all chopped finely)
and season well.
Place in a large bowl and cool.
Add seasoned breadcrumbs and a little of the tomato gravy,
enough to make the mixture pliable.
Divide the stuffing among the cabbage leaves then roll.
Place seam down in a baking pan.
Ladle tomato gravy on top,
and bake at 325° for 30 - 45 minutes.



Umbilical Cordon Bleu

Nothing is so beautiful as the bond between mother and child,
so why not consume it?
Children or chicken breasts will work wonderfully also.

4 whole umbilical chords (or baby breasts, or chicken br

What gives you the impression the E field is stronger than the H field?

Why not give the fields a strength in numbers so that you can compare the
two.

To make a true comparison you should use the same strength measurement units
for both.

In the first 5 minutes of an EE's education, the following quotation should
appear on the blackboard -


"When you can measure what you are speaking about and express it in numbers
you know something about it. But when you cannot measure it, when you cannot
express it in numbers, your knowledge is of a meagre and unsatisfactory
kind. It may be the beginning of knowledge but you have scarcely in your
thoughts advanced to the state of science."

: William Thomson, Lord Kelvin, 1824-1907.


Un-culled kids inhabitting the sewers of Rio-de-Janerio, never having heard
of Thomson, are better educated.

Outlandish educational claim. Evidence, Reg?

Hi Ed,

Now, you wouldn't be asking for him to express it in NUMBERS would
you? ;-)

Thanx for the yuletide cheer.

Pre-mie Pot Pie

When working with prematurely delivered newborns (or chicken) use sherry;
red wine with beef (buy steak or roast, do not pre-boil).

Pie crust (see index)
Whole fresh pre-mie; eviscerated, head, hands and feet removed
Onions, bell pepper, celery
½ cup wine
Root vegetables of choice (turnips, carrots, potatoes, etc) cubed

Make a crust from scratch - or go shamefully to the frozen food section
of your favorite grocery and select 2 high quality pie crusts (you
will need one for the top also).
Boil the prepared delicacy until the meat starts to come off the bones.
Remove, de-bone and cube; continue to reduce the broth.
Brown the onions, peppers and celery.
Add the meat then season, continue browning.
De-glaze with sherry, add the reduced broth.
Finally, put in the root vegetables and simmer for 15 minutes.
Allow to cool slightly.
Place the pie pan in 375 degree oven for a few minutes so bottom crust is not soggy,
reduce oven to 325.
Fill the pie with stew, place top crust and with a fork, seal the crusts together
then poke holes in top.
Return to oven and bake for 30 minutes, or until pie crust is golde
