![]() "Art Unwin" wrote When viewing the antenna from an equilibrium point of view which is a staple requirement of all electrical laws one must assume that all forces/vectors equal zero (Newton ) Following this dictum physics state that foe equilibrium the charge on the surface of a radiator does not move linearlly there fore, there cannot be a linear force or vector to oppose it. From this it is stated that there is no movement in linear form else where which includes the center of the conductor/ radiator when the radfiator is one wavelength or multiple there of. Now we have the case of a fractional wavelength radiator. In this case one is aware that charges do move in a linear direction as evidenced by "end effect". Therefore by following the standard laws of physics there must be a balancing force/vector in the opposite direction and the only place that vector could be is in the center of the conductor One should also be aware that a electrical curcuit for a fractional wavelength is a series circuit and a parallelel circuit for a fulle wavelength both of which are closed cuircuits when determining current flow of a radiator so one can itemise the electrical circuit in detail with respect to the components on the actual radiator to ensure compatability. Now according to my theory of radiation the forward current on a radiator is opposed by closed circuit eddy current which in combination provide a angular rotational force on any residing particle which allows for directional levitation or projection. When the current of the radiator reaches the end of the radiator it closes the circuit by entering the center of the conductor ( assuming the arrangement is not in a state of vacuum)under circular surface current cuircuit where it is still in existance. The internal current flow is solely resistive in nature comprising of theseries resistance of the material used and not radiative. Now David, if you can point to a description that differs to the above and follows the laws of physics I would be happy to look it up and study it , but in the final analysis one must be able to determine the state of the conductor at it's center at all times. David, my explanation is based on the world of physics as I know it. Hi Art Trying to build a picture here. Let's say I have a 1/2 wave dipole, and I drive it such that one ampere is flowing at the feedpoint. Let's agree to use amps RMS and volts RMS at 14 MHz for this example, just for clarity. If I measure the current a short distance from the feedpoint, it's a bit less than one amp. Correct so far? If I tease the antenna conductor apart and measure the current flowing on the outside with one RF Ammeter, and the current flowing in the center with a second ammeter, what are the two currents? Thanks! 73 PN2222A |

Thanks! 73 PN2222A Sorry. I have enough problems trying to explain my own theorem which follows Newton, Gauss and also Einsteins dream in identifying all four universal forces which provide the key to the explanation to radiation and discards the notion of traveling waves in the atmosphere. Until this group has the courage in disputing that the addition of radiators and a time varying current to a Gaussian arbitrary static field in equilibrium is mathematically identical with Maxwell's laws AND also accept the Grand Unification Theory which I have supplied the proof of authenticity change will never be accepted regardless of first principles that they learned in their only period of learning where they apparently were placed in a position of understanding all the laws of the Universe and every thing else. If any of those that are educated enough to take up the challenge from first principles then they are in danger of being mocked by those who cannot accept change,Thus it is safer to abide by books that are full of just conjecture with respect to radiation. There is nobody in this newsgroup who is willing to take the challenge and be subject to the ire of the many talking heads. The comparison of my extended Gaussian law of statics to the laws of Maxwell will never be attempted by a ham whether on this newsgroup or else where. On top of thatm, the theorem will never be attempted or accepted when applied to NEC or mininec programs with optimizer regardles of the fact that computer programs are founded on the laws of Maxwell which includes the four forces of the Universe plus the foundation of equilibrium NONE of which are included or accounted for in the design of Yagi's or other planar devices. To be frank,, most of this group have asked for a definition of the term equilibrium, this despite the fact that there is no law of physics in this universe that does not expect the condition of equilibrium as a a given for the validity of any law with respect to our universe. This is in addition to all suppliers of technical information to Maxwell to condense into a smaller number, all specifically stated that the information given were valid ONLY under the conditions of equilibrium As far as your question goes, you cannot create energy so the energy supplied is the same that returns to the source neglecting losses in the closed system i.e Energy supplied to the "system" cannot be overcome by the disturbances created by the initial energy Best regards Art Unwin KB9MZ.....xg which has never been extended |

. . . Possibly yes. However, ending a sentence in a preposition is a violation of proper grammar, up with which I will not put. Johnny's dad wanted to read him a story from a book, but Johnny wasn't interested. So his mean father sent him to his room without supper. After supper, his father went to Johnny's room to try again. And Johnny said, "Why did you bring the book that before dinner I didn't want to be read to out of up for after?" That was the record of six prepositions at the end of a sentence submitted by readers to "Charlie Rice's Punchbowl" in Parade Magazine oh, I dunno, 45 years or so ago. I guess remembering stuff like that is why I don't have room to remember where I parked the car or left my glasses. Roy Lewallen, W7EL |

This is in addition to all suppliers of technical information to Maxwell to condense into a smaller number, all specifically stated that the information given were valid ONLY under the conditions of equilibrium Give quotes. i want to see in the original writings where Gauss, Ampere, Coulomb, Ohm, Lorentz, etc all require some kind of equilibrium. Come on art, you claim to be above all of us who have studied such things for years, and yet you can not define even your most basic condition that you keep ranting about. So your homework assignment is to in one equation do this: Define Equilibrium. |

So your homework assignment is to in one equation do this: *Define Equilibrium. David, I am so glad that you keep writing. No I can't spend a lot of time responding because of the postings content. What I do find important is that everybody exercise to right of free speech as it allows all to determine who and what you really are Most people would look at a dictionary for themselves to determine what the word equilibrium actually means as well as the recordings of history where all the masters of the past has made a stipulation about the conditi9on of equilibrium as a staple of the validity of the laws that they espoused. You should also know that Einstein was convinced that radiation held the clues as to the nature of the four forces of the universe He never stumbled on the answer but he never ditched the idea of equilibrium as a staple for the laws of relativity. Nor have other discarded same in string theory or the burgeoning science of particles in our universe. I am betting that there are some knoweledgable people out there that do read your postings and place you in a certain category. I would also point out that those who try to distort the ideas of reflection are the owners of the largest threads on this newsgroup where there are many that exceed a thousand posting where many are unable to turn the espoused ideas of reflections into a closed circuit of understanding since it involves so many positions that are unsustainable to those familiar with the state of the art. All one has to do to destroy my theory and the new clues that emanate is to add radiators and a time varying current to that enclosed within a arbitrary border is in a state of equilibrium as per Gauss to determine the difference in the math to that espoused by Maxwell to detroy my position. All one has to do is to use any computor program on antennas with an optimizer, insert any dimensions that do not guide the computer in the direction of a planar design ie. all dimensions being non repeatable and then determine why the programs based on the laws of Maxwell consistently provide antennas that are in a state of equilibrium. No ham on this group have proved false my assertions with respect to radiation since their learning stopped at the point of leaving university where they still hold on to the books of yesteryear. On top of all this there is no evidence that there is any advantage in having rafiators in a straight line, or that size is a factor for any antenna WHERE there is accountability for ALLl the four forces that aid in the production of radiation. So David keep writing as I have given you lots of data to refute so that posters can understand who and what you are . Great day for antennas so get off the net and enjoy your self Best regards Art Unwin KB9MZ........xg |

Great day for antennas so get off the net and enjoy your self I am taking the day off from antenna work, i have a guest operator using my station for ss cw and i am just working on an update of my latest book... practical stuff for the practical ham, you will have no place in it nor need for it. |

The book idea sounds interesting. there seems to be a lot more printing outside theo academic world these days to counteract their iron hold on science discussions. The best independent book that I own is The secret of gravity and other mysteries of the Universe by Weldon Vlasak which I recommend to anybody in the ham radio world. Let me know when your book gets on the Oprah list of the book of the month so I can see you on TV At the moment I am putting a different rotatable antenna for top band on my tower while the weather is still good tho there are a lot of hitches that get in the way when at the top !.

Since, obviously, the signal MUST leave the surface, why not just travel it (shortest distance between two points--and all that) to begin with? I do believe it does travel the surface, if at all possible; however, given a very thin radiator and/or a very large PA, it would not surprise me if you can't force the current/power/VA to another route ...

Remember that the plate of a capacitor represents an inductor which in combination with a capacitor has the same constituents as a tank circuit except that it is not being subject to a time varying field. I would like to say that I was in error stating that the when programers made the computor program on antennas on the premise of a contunuous sine wave they are quite correct when viwing it from yhe stand point of a tank circuit. To make a jump from this acceptance, to one accepting the same occurs at rf, where a signal actually leaves the antenna and enters/"rides"/travels/propagates the ether, is easily made, at least by me. I think the case is slightly different, it needs a continued varied current to achieve a stable eddy current which gives the ability for levitated charge movement and in the capacitor case the point of least resistance is pre established after the first varient in current and it is the current movement inconjunction with the eddy current that provides the essential spin needed for inline projection Since, obviously, the signal MUST leave the surface, why not just travel it (shortest distance between two points--and all that) to begin with? Exactly . After the first pulse of current flow the point of least resistance is attained so yes the charge will travel at that specific point. When a capacitor breaks down you cannot see the path taken by the current on the initiating plate but you can see a point trace where the charge impinges on the reeiving plate as opposed to the whole area of the plate. Remember convention if correct states that a capacitor does not radiate I do believe it does travel the surface, if at all possible; *however, given a very thin radiator and/or a very large PA, it would not surprise me if you can't force the current/power/VA to another route ... I don't see how that could happen except when a charge is released it produces a lesser resistance route by ironizing of the medium travelled either in the initial case or of a resultant discharge travelling thu ozone.

Art, will you please tell us who has distorted the idea of reflection?
