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). http://home.comcast.net/~kb7qhc/antennas/navy/ 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? Jerry KD6JDJ 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. 73's Richard Clark, KB7QHC 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. Jerry KD6JDJ |
