Hardly worth going any further into the mysteries of this invention. Dipole envy? :-0 Abstract: http://ieeexplore.ieee.org/Xplore/lo...8/01282130.pdf It's "Disk loaded monopole" You didn't read the patent either, did you? ;-) I don't blame you. It is like reading the telephone book (aside from the obvious sloppiness). 73's Richard Clark, KB7QHC |

Yes, but then you didn't see what Mr. Vincent "seen", enough to get a physics dept. of a university to back him, and mentioned by arrl! And, gawd knows, arrl is a power to be recognised! COUGH! Doesn't matter to me. I don't build my antennas for the ARRL. I build them for me... I'm not even a member of the ARRL.. Never have been. But then, the naysayers have painted Mr. Vincent as a con man, indeed, not just a "con man" but a "SUPER CON MAN!" The type of con man where bankers lock their doors at his approach, men step before their wives in protection, wives shade the eyes of their children, massive and powerful men grasp their wallets tightly and expert con men run before him in fear, envy and loathing! :-( I don't think he's a con man at all. But I don't think the information he provides give anyone enough info to make an accurate comparison. Or at least from what I've seen. There is nothing really "wrong" with his antenna. I just think there are better ways to get what he is after, which seems to be mainly improved current distribution. People have known how to improve the current distribution for years.. Nothing new.. And it sure does not require multiple loading coils to accomplish. His disks? Nothing more than small capacitive hats.. Nothing new there. I just don't see the hype, and in fact, I think his design would end up being inferior to what I would cook up for the same height mast and stinger. Cecil seems to agree with me, so if you don't believe me, maybe his word will mean a little more to you. The *best* way to load a short vertical is with a large enough capacity hat to load the antenna with *no* loading coil needed. And that is what your's truly would build if I had to have a contest against his using the same height whip. And the current distribution in such a case is pretty linear across the whole whip. You ain't gonna beat that with a bunch of multiple coils, disks, linear loading, etc, ad nausium.. But if you want to try, be my guest.. MK |

And that is what your's truly would build if I had to have a contest against his using the same height whip. BTW, I realize if the antennas were for a low freq, I might have to use a coil in order to avoid a hat that was just too big to handle, but still, I would concentrate as much capacitive loading at the top as I could, and use the minimum inductor value to match the antenna. If we both have to use coil loading, mine should win. The current distribution will be more linear on mine. And in a case using a large hat, it really doesn't matter where the coil is. The current distribution will still be fairly linear as long as the hat is big enough. That would be about the only case where I might consider a base loading coil to reduce coil windings. MK |

Regards, JS I think it would give me the better antenna in this case. I doubt he would want me at one of his seminars.. I'd be one of those hecklers that he has nightmares about late at night. But in my case, I would whip out my antenna and whoop him right there on the spot if he was brave enough to compare. I repeat what is proven to be best. I've already tried all his methods, and proven them inferior by testing. I'll back up my jibber jabber with real working antennas. Would be simple to set up too.. All I need is a standing mast like yours, and a few wires to string out a large top hat. I wonder what his alphabet soup would buy him if he lost... :/ MK |

[stuff] Actually, I don't think I explained that well--for want of a better explanation ... Take the Michelson–Morley experiment. They were attempting to find the equivalent of how the doppler effect affects sound in air. However, if the way matter affects ether is similar to the way air affects sound, the earth and its' atmosphere would be a less than optimal test bed. Indeed, if you take the horn from a train and place it in a long train, you would loose the effect, the skin of the train deflects/slows/distorts/whatever the air which causes the effect. Now, if someone where to reconstruct the Michelson–Morley experiment from the nose of a space shuttle (no matter intervening or massive matter in close proximity), to mirrors traveling at the same speed and in the same trajectory of the shuttle, perhaps a quite different conclusion would be reached. Especially, if the matter of air and proximity to earth is masking anything enough to throw off the experiment. I know unexpected results were obtained when a long tether was let out behind the shuttle, and never explained to my satisfaction. Perhaps that is a somewhat better way to express what I attempted in the post this one responds too ... Regards, JS |

That is simply all I point out ... an open mind never knows for certain. Regards, JS He has done everything to do with antennas. He has also read the WWW from beginning to the end, nothing new he has done it all. I would imagine that the antenna company that he designed antennas for gave up and went bankrupt when he said he was going to retire. I would imagine that is why the space ship landed today in California no point in taking risks now that he has left. IEEE is looking for an experienced antenna designer with extensive knoweledge of all types of antennas with extensive experience in determining worthwhile projects and be able to smell those that would fool others. Must be able to provide evidence of achievements that have benefited the advance of science. Experience in winding coils accepted as well as evidence of climbing towers to replace light bulbs. Must be a EE with a Masters from an accredited college with a history of writing papers on the science of antennas as well as able to judge antenna designs presented to the IEEE. Trench diggers for cable installations need not apply. Maybe he will not be around to long as he is evidently better than sliced bread in all the sciences. I imagine that he made more money on the stock market than the average broker |

[stuff] Well, it is good to remember, the boys in R&D (the ones who come up with the new stuff) get paid just as much to find out what doesn't work, as the do to find the stuff which does ... It is the ratio of the two which determines if they keep their jobs or not ... well, unless they work for gov't ... Regards, JS |
