Congratulations Art, you are now in my killfile.
Don't bother responding - I won't see your posts anymore. There's enough negativity in the world, I don't need it in an antenna newsgroup. Man oh Man, anyone who slams Roy....... 73 forever, Rick K2XT |

"I refer you to the thread I initiated on gaussian antennas where Roy was the first to respond." My dictionary says: "Gauss`s theorem----The summation of the normal component of the electric displacement over any closed surface is equal to the electric charge within the surface." James Clerk Maxwell studied the work of others such as Ampere and Gauss to develop his equations defining the relationships between fields, charges, and currents. Maxwell found that dislacement current should produce radiation the same as conduction current. So he made a correction to Ampere`s Circuital Law. Art is right. Discovery is a continuous process. Maxwell`s equations have now been adjusted for curved space and time. But, I`ve searched in vain for "gaussian antennas". If Art has an invention, maybe he will explain.

Best regards, Richard Harrison, KB5WZI O.K. you haven't been around for a while so I will give you the benefit of the doubt in that you are not aware of my new series of antennas that gives the yagi a run for its money and infact meets the needs of a lot of industries. Many have asked for a mathematical aproach accepting no other well that is their problem. I am going back to first principles which most of the masters did without forsaking equilibrium and the mathematical conformity that must be kept. So if you have an open mind, pen and paper I will start. Anybody who is aware of Gauss can think back to the enclosed ballon or what have you where there is a pill box at one end. Hopefully you have drawn that. Now on the pill box you should be able to draw say three static images Hopefully you have done that O.K. Now some of those who are not familiar with things will get lost at this time. For the educated you can now modify the static field that you have drawn and expand it by making it a Conservative field where theoretical vectors are added to each static partical bearing very much in mind that all vectors are theoretical and all have "zero" length. O.K. take a moment and look at what you have drawn which is a rfield of projected static particles with theoretical vectors on them and nothing to show inside the enclosed arbitary border from whence they came ie we did not show where the static particles came from. Now when you applied vectors to the static particles you added two each at right angles to each other, Why? Because for the vectors to represent a radiating array in any form it must be in all three cartesian directions. At this time we will project from each static particles a dotted line to the end of a element length such that a cluster of elements now show where the static particals came from. Hopefully you are still with me. Gaussian law is o.k. as far as it goes but when deevising antenna arrays we need something more i.e the addition of time. So we pull out the written version of gausses static law and enlarge it to account for a time additive. And we can do this by adding the metric of a space in time to the original statement bearing in mind that to do so equilibrium must be maintained. Dinner is here will resume in half an hour. Take time to think about what I have discussed so far but without pre descisions so that you can follow the flow better later. Art |

Earlier when I asked for vectors to be placed on the conservative field some of the more knoweledgable went a bit furthur than I asked and placed a dot in the middle of the static particles or a plus sign both of which denotes the direction of current just like you would see by looking at the ends of an arrow i.e. a point says the current is moving towards you if, if, time was involved. Since the new law containing time is something new we have to be sure that we still have maintained equilibrium which means that the current in each element must reverse direction at the same time which also states that each element is resonant in situ where it may be close to or at an angle to other elements in the array and ofcourse the array in its entirety must also be resonant. It can be thus seen that before current flows such the arbitary border is breached which is the comencement of radiation that if there were enough elements within the closed border we could in fact have two vectors pointing to the front instead of just one with the yagi. In adition since all elements are resonant tho not necessarily of the same length reactance in the cluster gyrated towards zero which leads to efficiency. So we can analyse or deduce that the border breaches momentarily when current direction changes and quiqckly close to sustain equilibrium. Now the above picture encompases the action that occurs in a space of time in accordance with the origianal gaussian law. QED ? Well we have a story only so far. So I placed a array on my computor where the elements were parallel but at different levels in height where all elements were resonant to calculate the field. This was sent to another person, a PE,to check the results against another program i.e.nec 4 where it faired pretty well against a yagi. Next with a program that has some self determination by the use of variables was given the task to provide the best antenna at a certain frequency to find the best arrangement for a particular desirable which it did. But it was not a yagi but what I called a Gaussian array where all elements are variable in length angle ,position and ofcourse resonant. With more time passing by it was also found that in some cases one element could be slightly detuned to provide an imperfection in the border to predetermine the breach point. Late rit was found that elemements parallel or at right angles to the earths surface is not a given, not surprisingly because the vector resultant is always offset from those angles. There is more to investigate and I would like Arie to repeat ny tests on his programs because it is free and thus no reason to mislead. gentlemen I have typed this quickly and I know I have mispelled or misarranged words and all that but please learn to live with it for a while and I will be happy to answer any questions or doubts as long as thing dont get nasty like being called a complete idiot Art |

According to my computor(sic), you have taken over sole possession of third place in number of posts on the RRAA newsgroup.Number one is, of course, Fractenna. Frack's total will never be matched, so second or third place is quite honorable. While we all miss Chip, it's better that you and he are not on stage at the same time. He would learn that your newly discovered Gaussian Array is nothing more than a self-similar array, falling under his broad portfolio of Fractal Patents. That fact would upset his equilibrium, thus ensuring a flurry of threatened lawsuits. Regardless, congratulations are in order for your accomplishment, as the educational aspect is second only to the entertainment value. Mike W5CHR Memphis, Tenn. |

Best regards, Richard Harrison, KB5WZI Richard, I did find a number of references to Gaussian antennas on the web. i.e. http://www.flann.com/Products_Home/A.../gaussian.html The only conclusion I can make is that the radiation pattern appears to be a Gaussian curve. This does not seem to be related to Art's postings. It appears that Art must be on my blocked senders list, since I found responses to one of my earlier posts on Google's archives. I could not entirely follow his rational, but one of his complaints was "I did not provide the polarity of the patterns". If he is interested I can provide all these data from the NEC output file; also the NEC code. I would first need to know his e-mail address in order to remove it from my blocked senders list. Regards. Frank (VE6CB) |

Man oh Man, anyone who slams Roy....... 73 forever, Rick K2XT Does anybody disagree or agree for that matter that the expansion of Gaussian static law to electro magnetic law is correct or in error, Anybody. Why the reluctance to talk about the basics of radiation? There are no approximations or excuses or fudge factors pencilled in the analyis. It produces the same results every time when adressed which is not the same as in NEC program useage. The basic laws of the masters which is the under pinnings of NEC are specific and to the point. It is the programer that is introducing the errors and he is the checker of his own work. If the works of the masters reveal something new when the formular is used who do we shoot, the programmer, the masters or wait for somebody else to do some work and add it to the program based on empirical work? Well it appears that for the present all choose to ignore it because lack of knoweledge is not hurting anybody. Shame oh shame Art XG |

You have no NEC results. There are no approximations or excuses or fudge factors pencilled in the analyis. You refuse to discuss the obvious errors of: 1. Scale (explain how 6 inch elements resonate at 200 MHz); 2. Elements described as orthogonal to an axis (they are not); 3. Any number of gain claims through software you challenge as inaccurate; 4. Ignoring historical work that has preceded you. Shame oh shame Congratulations! A comment like that, would probably get you kill-filed from the new moderated group - which makes you a troglodyte like the rest of us. ;-) Have you though of cleaning up your act and doing a dog and pony show for them? 73's Richard Clark, KB7QHC |
