Art Even a 6ft verticla can be made to perform reasonably well on 40m when used with a good ground system, the ground system thay were using is probably as close to ideal as you can get. The big difference is in using a short antenna with a poor to mediocre ground system, then they stick out like a sore thumb I did nt see any qualitative data given in the test results except saying that the short antennas performed nearly as well as the full size antennas. Hell, Ive heard 20db down reported as "nearly as well" or as "comparable with". Im sure the numbers had to be available so why werent they posted.What would be the point of doing a test like this if you didnt get qualatative data?

"There are two poles in the antenna, and where I place the poles in relation to one another-how much I bring the two resonant frequencies together or spread them apart-enables me to emulate different antennas, from a quarter-wave to a five-eighths wave." " 2) "All I have to do is tap the helix at its base, and you get a perfect 50-ohm match with out any lossy networks as are required for other advanced antenna designs," said Vincent. 3) "Eight years ago, antenna design was 90 percent black magic and 10 percent theory," said Vincent. "But now, with my design, they are 10 percent black magic and 90 percent theory."

The testing was done by a independent source so a review of the results shows what you get. The patent was accepted by the PTO so on the surface it would appear that there is something new here even if the experts are baying at the moon ahead of time knowing that all is known about antennas. It would be interesting if the independent test reports were included in the patent request which would infere that the PTO confirmed the propriety of the tests, usually by being present. Note the antenna was designed using a propriety computor program which the range test confirmed after the fact. |

The dipole was 35 feet long and had two loading coils about 4 feet from each end. I fed it at the bottom end. The thing would be fairly narrow and would require an autotransformer or tuned match at the base (or a quarter wave open stub) but the PATTERN was very nice, indeed. With all that current up that high, it's nice and flat and low to the ground. Gain isn't spectacular, though, only about 1.5dbi. But phase 4 of them and you're up there with the big guns, though probably only for about 10-20khz of the band. And, on receive, it's a horizon-scraper.

And, any decent modeling code(s) will have extensive validation against range tests, so it's not much of a surprise when the antenna works as modeled. The surprises come from aspects that weren't modeled. Let us have a fresh look at the emergence of this new antenna where amateurs confess that they do not know all the details but it MUST be a fake, but for why they cannot explain. The Naval antenna testing facility tested the antenna as they do with all military antennas. The test figures are published on the web ( put the antenna initials in Google) The computor program was home brewed and verified later by the IEEE, again see report on google. ) The test performed by the Navy also confirmed this home brewed report before the IEEE reviewed it after the fact Now I am in no way saying it has merit tho the methods used to check his claimes appear to have validity. Remember that I have provided a new antenna on this newsgroup. The mathematics were supported independendly and STANDARD computor programs confirm it but again amateurs cannot find themselves able to accept anything new. Look at Cecil's page where he has a Zepp dipole for all frequencies using stubs, do you think they believe Cecil? I wrote up a similar antenna where the tuning mechanism is a loop with a dipole protruding out from each side and where the loop is tuned with a variable capacitor which also emulates the Zepp for all frequencies( See the Gaussian thread). Even when hams model it they can't believe it, completely disregarding scientific back up. Remember it is AMATEUR radio who learn radio basics but only in a few cases actually UNDERSTAND the basics. I also provided a three element antenna on a eight foot boom that excels the specs that ARRL optimised in every region and at the same time provided more gain per unit length than the accepted Gain/Boom length graph printed in most books. Again amateurs are loathe to accept anything new except when it is in a book that they can learn from but not necessarily UNDERSTAND. As a side note, one of my past PTO examinas did not know the difference between parallel and series circuit but that is O.K. His job is to enter key words from an application and see what patents emerge so he can send them to the applicant, from then on it is resolved on grammatical terms . I would like to see a thorough examination of this new vertical antenna if only to find out where the Navy and the IEEE were in error. I certainly would not trash it on the basis of comments by amateurs on this newsgroup unless they provided credible proof that they were knoweledgable about the specifics of the antenna and could then provide credible reasons why it should not be accepted. That ofcourse will never happen in this newsgroup. Look up at the howl that emanated on this group on such a simple subject such as Gauss together with conservative and non conservative fields. We even have teachers in this group who could not come forward to explain it to others as well as some who denied any possibility of a connection. This is just an amateur group who likes to play word games with others to get a "gottcha", It is not a scientific group with credible backgrounds that by itself demands attention, it is just a group of amateurs from various fields and pursuits where their every post reflect their true abilities.

I did that 12-15 years ago on my first mobile antenna.. "combining a helical mast with lumped loading coils." Big deal... Myself, I think he would be better off to dump the helical windings, and just use all lumped loading.. A large high Q lumped coil will generally have less total loss than using any narrower dia helical winding along with a lumped coil. I did away with the helical windings on mine. And I still have good current distribution. And slightly less loss. 1) "The technology is completely scalable: What isn't ? " 2) "All I have to do is tap the helix at its base, and you get a perfect 50-ohm match with out any lossy networks as are required for other advanced antenna designs," said Vincent. Who says other designs have lossy matching networks? Mine don't.. He calls that an advanced antenna design? Hummm... I'll reserve comment... 3) "Eight years ago, antenna design was 90 percent black magic and 10 percent theory," said Vincent. "But now, with my design, they are 10 percent black magic and 90 percent theory." This is even worse... That statement is just total BS... The above from this URL: http://www.jefallbright.net/node/2718 He mentions being able to create these in 1/4 to 5/8 design--so, create a 1/2 and loose the radials and salt water ... Wow, that's really advanced.. I wish I could think to try that... :/ It is difficult to find real detail on this antenna! Makes 'ya wonder, don't it? JS Not really.. The antenna is ok I guess, nothing really horrible about it, but I don't see anything new. In fact, some of his statements are sort of silly.. IE: "For instance, in a normal quarter-wave antenna the current continually drops off in a sinusoidal shape, but these antennas don't do that," said Vincent. "The current at the top of the antenna is 80 percent of the current at the base." Wow..I suppose he thinks his antenna will outdo a full quarter wave then I guess.. Good luck in the contest is all I can say... Then you have this jibber jabber.. "Using a DLM antenna one-third to one-ninth the size of standard quarter-wave antenna, he measured nearly 80 percent efficiency, when conventional wisdom would dictate that an antenna the size of a DLM should be only 8 to 15 percent efficient." Look how vague it is.. Can't even get the size of his antenna right.. So how can we decide what to compare it to? Also he makes no mention of ground quality, radials, etc.. It's easy to sound "advanced" when you don't give enough info for anyone to prove you wrong... Anyway... ho hummmm.... As you can tell, I'm really excited about this new fangled technology. MK |

... And, any decent modeling code(s) will have extensive validation against range tests, so it's not much of a surprise when the antenna works as modeled. The surprises come from aspects that weren't modeled. Jim: Your text is interesting. I went ahead and put together, on the little I could glean from the info on this, an antenna. I marked a pvc pipe on both sides, drilled it, and put the wire though, basically as a series of hair pin loops. "Tap'ed" it, obtained a 50 ohm match (had to use a variable cap) and it works, I need more data ... I need a complete pic and data so I can duplicate his construction ... I have an open mind. However, this "thing" is so simple, it is better I confirm or reject "it" on my own observations ... it may, or may not, be nothing ... Regards, JS |

... simple answer... its a 3 year old article, who do you know that is selling them? if they were anything special someone would have picked them up and started marketing them. speaking of which, who have you lined up to sell your 'gaussian' designs art? can you even define it yet?? Funny you should mention that ... I tore apart last years cell phone. There is a strange looking "antenna" which is etched onto the pcb board--strikingly similar to what "he" (the guy with the "weird antenna" ) has described ... JS |

ROFLOL Anyway, in the land yacht, I use a "boosted antenna" which utilizes a mars device--works surprisingly well, and was purchased at a flea market for ~$10 bucks. The thing is crap ... at least technically! I know it should not work as well as it does, XYL wants me to replace it with a mobile direct tv setup--hey, what can I say, I believe in fairy tales? Anyway, I was able to watch the lost tv series on it when we went to visit family ... I have time to play with such, it keeps me out of jail. :-) Regards, JS |

Hi Tom, It support's Arthur's faith in the PTO giving authority to invention: As a side note, one of my past PTO examinas did not know the difference between parallel and series circuit but that is O.K. Of course, Arthur also leand on their credibility to recognize something "different:" The patent was accepted by the PTO so on the surface it would appear that there is something new here even if the experts are baying at the moon ahead of time knowing that all is known about antennas. Considering that the PTO can be condemned and praised for the same thing is about as clarifying as his explanation for gaussian antenna theory. The original quote above (drawn from an actual patent that teaches the "different" antenna theory of the inventor) has its problems too, of course, but its "difference" makes it patentable. Afterall, who could possible beat him in the marketplace by stealing this idea? 73's Richard Clark, KB7QHC |

Publication is NEVER required with respect to establishing prior art. At least two things automatically support "prior art" status: 1) Valid documentation (but not necessarily publication) of the prior art. This usually means something like a lab notebook entry, witnessed by others. 2) Shipping a product that contains the prior art. No notification or publication is required. There are undoubtedly other means of establishing prior art that do not require "publication". In the US, establishing prior art is a matter for courts and lawsuits, so YMMV. 73, Gene W4SZ |
