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.
