Yeah, used to be that way in California--last earthquake destroyed
that--maybe you heard about it? :-D

Sure, assuming energy is being "used" to perform an operation in which

Your ignorance is showing, Jim. It takes absolutely no work to
transform impedances because those impedances are virtual and
meet the IEEE Dictionary definition (B) for "impedance" which
requires zero work.

It might be better to say the reflected energy is performing
a "function" which requires no work (possibly a lot like being
a physics professor). :-)

Amazing! I'm watching the time stamp on these missiles... erm..
missives, and you guys are almost in chat mode!

Respectfully, y'all ought to step back an catch yer collective breaths! ;^)

No Cedcil I don't have a problem with vectors but apparently those
that follow the sciences of electricity do. From time memorial
electrical engineers have used iron filings to determine
the field lines of an inductor. Yet at the same time we do NOT use a
ferrous material for antennas.Thus when using E and H in radiation
calculations one must determine the the phases of both that are
applicable to the material used. Where the books of old place the EH
vector at the pont of radiation as 90 degrees to each other this can
only be seen as representitive of a ferrous field, where as, a
diamagnetic field vector is exactly the phase of the electric field
vector, putting aside for the moment the "curl" vector. When
considering a radiative circuit one must fully understand that the
current creating the field
is the instant expiration of a capacitor. When a inductance accepts
such energy to generate its field one must determine the material used
to ascertain the true shape of the field. It is no coincidence that a
diamagnetic field is noted for its levitation properties that a
ferrous material cannot supply.So instead of accepting formulae where
a magnetic field is assumed to be consistant the same for all
materials for all materials one must understand that this assumption
is not correct even tho it has consumed the sciences of today which
has forced the generation of the new sciences of the day. It is time
the books were redwritten to reflect the true workings of nature
around which Newtons laws still stands.
My two penny worth from a mechanical engineer.

What is even more amazing is that someone in CA can
reply to my TX posting before I posted it. :-)

Reminds me of a tale. A guy in Abilene, TX was taking
a bus to Hobbs, NM. It left at 12:00 and got there
at 12:10. When asked if he wanted a ticket, the guy
replied, "No, but if you don't mind, I'd like to watch
that sucker dig out when it leaves."

Thats what would be fun! a #rraa irc chat channel! just think of the real
time discussions that could go on there!!

This is truly sad. I thought you had finally begun to understand this

still totally confusing phasors with field vectors. They are utterly,

Gene, in order to alleviate your ignorance on this subject,
I have come up with a lectu

It is titled: "Lecture-38-Phasor Form of Poynting Theorem" - enjoy!

Wow! I never thought I would ever see this information outside
of a university lecture. There are a number of these lectures
available. Anyone who is serious about this subject line should
avail themselves of the considerable technical knowledge contained
in these lectures.

Stop right there. The type of resonant circuit depends upon length and
construction of the antenna. My 20th edition of The ARRL Antenna Book
says on page 2-6:
"Near its half-wave resonant frequency, a center-fed lamba/2 dipole
exhibits much the same characteristics as
a coventonal series-resonant circuit."
