However, returning to my own recent shipboard experience and antennas
there, I will later today post a link to a dozen or so pictures. It
will include shots of Guss' Loops. I dare say several of these
pictures will provoke much head scratching (but only to those few
actually interested in antennas here in this forum).

I used to have the nomenclatures of all those antennas memorized, but,
alas,
having gotten away from EMI inspections in 2003 and having fully retired
last year, all I can call to mind is the AS-2815/SSR-1 (your "Drooped
Cross
Horizontal")

You zeroed in on some cryppie antennas. I rocognize the biconical
dipole,
an HFDF antenna and a Rubicon antenna. They're often found together on
an
Aegis cruiser. (Makes me want to put on my coveralls and get back out
there -- or maybe not.)

Hi "Sal"

I'd like to know more about the Drooped Cross
Horizontal"). Do you know the frequency it is designed for?

Hi Jerry,

I built a model of it, and from by guess and by golly, I presumed it
would be somewhere in the middle of the VHF/UHF Shipboard Band
(225-400 MHz) and made it resonant at 300 MHz (arbitrary selection,
mind you).

Let me know if you want a copy of that file.

Hi Richard

Yes, I sure would like to see your EZNEC file. I'd benefit from seeing
how you modeled it too.
The antenna looks like it iis designed for satellite reception.
It interests me to consider that the "DCA" that I developed would
(perhaps) be a design concept applicable to this operational requirement.

Uhh, those eznec files, they are kinda like a high-school\college friend
recently explained to me in financial terms:

"If you have a sheet of paper claiming a "controlling interest in gold",
all you REALLY have is a sheet of paper! If you are looking at the gold
you are "invested" in, you REALLY HAVE the gold!" wink

But then, it is only when you realize there have been more "certificates
in 'controlling' interests in gold" issued than the amount of gold which
exists in the world, that, you suddenly awaken to a HARSH reality! (like
some have "been had!")

Read about "The Great Depression", I tell 'ya, there are clues to be had
there! I mean, really, it is the same old game, just new "marks!"

Hi John

You are right, this EZNEC antenna modeling program is like gold to anyone
interested in learning about antennas. You are additionally right about
the fact that all you need is a piece of paper (or monitor) to display
aspects of an antenna that would otherwise require thousands of dollars to
duplicate.

I certainly don't wish to invoke your anger by pointing out your
ignorance, but guy, eznec is only a front-end to eznec ... mmana-gal
does exactly the same thing, has no limitations and is free ...

Eznec does nothing but create an ascii text file and feed it to the nec
engine, and displays the results ...

Sorry guy, it just looks complicated to you ...

And, of course, no disrespect meant to Roy ... he did a nice job on the
front-end ...

Just caught the error when I hit send:

Glad to see you are coping, Mr. Anonymous "John". Good save chuckle
