Isn't life good when things come to a successful end such that the time has come around again as it always does to throw the old books away of past generations and go with books of the new generation? Best regards to all Art Unwin..KB9MZ..... ex UK Art Science is about building on the foundations of the past and not about throwing away books. The old methods of calculation still work fine, its just that in the light of new knowledge we can refine the methods to produce more accurate results. All of our achievements to date have been built on the foundations laid down by past generations and it is foolish and dangerous to dismiss or ignore any part of history. Never, ever throw away a book - well maybe the ones by Catherine Cookson et al :-) Regards Mike G0ULI |

Are you quoting Gobbels now? This "golden city on the hill" fluff hardly describes any antenna of remarkable ability. The alternative is so much misty eyed and fond desires (superstition) like a pre-teen girl's scribbling into her diary. 73's Richard Clark, KB7QHC |

Now I have Richard firing his nonsense across my bow with the credentials of a degree in geography that trumps all others in the hope that he can get somebody to talk to him. Seems to have worked ;-) Oh, by the way, it is a degree in English (you know, the country you hate - now THATS geography). By the by, I see you still lean on MIT who left here misquoting Feynman and having mixed up his math (at least you both can have a reunion when your next anniversary comes up). Can I anticipate another sob story about how wicked we are here? (Boy, those "gentlemen of eham" sure stomped your ego.) 73's Richard Clark, KB7QHC |

I think it is quite apparent--for every one success a man will ask a thousand questions--try a thousand things. The easy stuff has all been done--the more difficult lays before us. Those before us never thought they left a completed work but only wished for others to follow behind them and further their thought, experiments and discovery. Hang in their, almost every concept we now accept (until better presents itself) was scoffed at and belittled, men have been imprisoned, and worse for even challenging accepted principals and thinking ... Hang in their, asking questions has never hurt. Just choose those more capable to interact with. Interacting with self-important morons never bears fruit ... and you know about news groups.

Regards, JS Fully understood. Odd thing is that 73 magazine used to make a good living by printing details of various antenna building and I admit I built a few of them.Ihave described the modifications needed for the new university antenna and for some reason see no reason to build it because it is a dud. I know you built the university antenna to check it out for yourself but I don't know of anybody who did the same thing to verify the claim. So it goes for the simple modification I supplied which if I am wrong gives loads of ammunition to every body to shoot me down once and for all with factual details but they seam scared to search for the truth. In the absence of knoweledge usually resort to insults and name calling and I see you got such a burst today. Remember that time when a guy appeared with his new NEC 4 program and wanted to model a simple arrray I supplied? Nobody would help him in checking things out and it took a personal E mail from somebody who did not want to be identified to help him with the proper useage of the program. It proved the veracity of what I had supplied dispite the lachof assistance to prove me wrong. As yet nobody with knoweledge of the state of the art has taken me on with respectto what I have discovered. I have had posts given where I believe the central theme was poetry, others who said they couldn't understand despite posts given by a Doctrate holder, ofcourse there are many like the blasting that you just got which should invite back the multi posters that decimated several newsgroups. What I am doing is sharing my work so all can enjoy but if hams are satisfied with lesser antennas because of the poor conditions so be it. But to try and stop thespreading of a particular advance to protect their so called resumes as being experts is really hard to fathom. I thought it would be a delight to all if somebody refuted the mathematics given but only silence reigned and then joined by name calling. Look at todays posting, how many were devoid of insults and name calling, I think that they finished up in the majority so what does that say antenna talk by hams? I am beginning to wonder with the spectrum being in such demand if the FCC would be justified in selling the amateur frequencies since it is certainly not the same when the frequencies were given, a listen to repeaters or a review of newsgroups going ons must fraustrate them very much. After the upcomming sale of frequencies which is in demand by industry I can easily see pressure on ham frequencies which is costing not contributing to the coffers. The idea that we are a public necessity was down graded years ago by industries inovative ideas so hams have a hard time now justifying their position. In the past it was often said that it was amatures that advanced the cusp of the science well we sure are not doing that now! O well let the discussion move away from mathematical analysis of antennas or new designs and get back to argueing and calling people names e.t.c. so all can participate including those who are true hobbyist that do not wish to concern themselves with the engineering background but who also want to participate in the augument side that most hams relish.

However, to some who have already built antennas which work, contrary to eznecs claim they won't, it is quite obvious current beliefs, equations, charts, theories, etc. are in some degree of error ...

The tank circuit is a electrical circuit that is also the circuit of a full wave radiator regardless of how the extended mathematics and my work portrays. It clearly shows that release of energy by shorting the energy source is how an efficient radiating system works i.e two energy sources continuing a pendulum swing as it were. Attack that if you wish since the books validate that without reference to equilibrium or Gauss. Much clippage, then With all the above I rest my case especially since nobody has refuted any of it in scientific terms which includes mathematics. ________ And, Art, you haven't posted the mathematics to prove or even illustrate what you believe about this -- which would be valuable to you, as your beliefs are so different from antenna engineering practice and field experience. You will have more credibility and respect if you post your mathematical proof so that others can investigate your beliefs using scientific methods, rather than persisting in your challenges for others to prove you wrong based only on your prose.

RF Already done all that on this newsgroup. Sweep for Gauss or gaussian and it will get you up to date Regards Art |

I personally have never had a QSO using a simulated antenna. :-) It also works the other way. By accidentally violating the modeling guidelines, I came up with a simulated omnidirectional antenna with 24 dBi gain. Want to build that one? -- 73, Cecil http://www.w5dxp.com |
