Dear John Smith (no call, no location)

Your questions contain assumptions. You assume that formulas amiable of
being programmed into a TI calculator exist for what it is you wish to do.
I doubt that they exist.

To borrow a term from your job, top-down is needed. Start with the
ARRL's Antenna Book. When you have digested its teachings, read either
Kraus' 3rd edition or Balanis' 2nd edition. Start at the beginning and
follow the road. It will be an interesting journey.

Yes, I am quite sure you are correct.

And, perhaps no one knows, or no one does it the old fashioned way and has
the formulas and steps at their disposal, I may have to seek other sources
than here.

However, I am a software engineer, once I understand the underlying math
and
methods I can write such an application myself.

When the final drafts of these programs are released, antenna design, I am
sure you will just draw your antenna on virtual graph paper with ruled
lines, such as many of the draw programs have. And, be able to add any
inductance or capacitance just by selecting the point with the mouse, and
then entering values--the application will do everything else for you,
including making suggestions for improvement, matching, special
conditions,
etc, etc--much like CAD (Computer Assisted Drafting) applications.

However, whether I use software, or simply divide 468/Fmhz, I still get a
half-wave.

It is fine if one wants to rely on software--I make my living on those who
do, I LOVE those people!--I just don't wish to invoke that method, later
when my understanding is absolute (well, greater than it is now) I may, or
write software specific to my needs...


Warmest regards

You wonder why EZNEC reports such results and then you go discover

antennas as any other single source including Dr. Balanis' graduate

that, in large part, to ELNEC and EZNEC.

If the formulas, charts, etc. don't exist, then I am extremely lucky. Most
of the time (OK! Maybe ALL the time) my efforts just end up duplicating what
past expermenters have already done. I make notes as I go, if I don't find
what I am doing in some other obscure work--or as knowledge another has, I
will be tempted to place it in a form where others might use it.
What I mean is, I will not be disappointed--and very happy if what you
suspect is true.
"Top Down" (hey, is that guy in a convertible?) is great, however, bottom up
has its uses too... OOP(s) (a pun--Object Orientated Programing--for
non-coders), I hope some of my old professors aren't around here! (Darn!
that Richard, now he has me doing it) grin

Well "John Smith," wherever and whoever you are, you are receiving valuable
advice from several quarters.
Our students are required to use top-down programming in computer
engineering and in computer science classes. If your professors did not
convince you of its importance, far be it for me to try.

J:

College was and is a great institution.
However, the most valuable professors/instructors I ever had the pleasure to
study under seemed to share one common element--they had all first worked in
private enterprise before entering the academic professions (scouting rounds
a guy out!)
My first degree was in electronic engineering. When the focus of this
seemed to move off shore and other employment opportunities became available
(and the Apple, then the IBM PC, came to be), I returned to college and
focused my attention in the field of computer science.
Being an older student at that time and possessing a bit of "street-smarts",
I was able to side step issues which I had found NOT be in "vogue" of my
instructors beliefs.
Although these institutions are a great forum for debate and argument--I was
able to see little value in endangering my grades with such which would be
contrary to my instructors favorite pet ideas (indeed, while in their
classrooms, they all thought--I thought, they were the most handsome (or
beautiful--if female) and gifted instructor(s) I ever had the pleasure to
study under grin.)
Some instructors are quick to point out, "There are NO dumb questions, just
dumb people who don't ask questions."
However, although they may state the above--following their own advice
seemed to be a bit more of a challenge to many of them and, some were better
in the implementation of that ideal than others; somehow, it left me with
the opinion that a more accurate translation to this advice would have been,
"If you don't agree with me and the course material I have chosen for this
course--YOU WILL PAY!"
But, I make no mistake--I am humbly indebted to ALL instructors for their
time and efforts--I value all who lives I touched in those hallowed halls.
To this day, I do work with encryption/decryption methods and protocols.
Frequently I employ another questionable practice--security through
obscurity; this fills my dreams with seemingly psychic visions of past
instructors cringing in dark corners in loathing contempt and fear of such
arcane and cheap methods...

Rather frequently I utter (under my breath), "Whatever works!" guilty
smile

Warmest regards,
John
