Gaus did contriubute to the Maxwellian laws which is accepted. The static law wsas not the particular gaussian contribution. Many have taken this that tho Gauss contributed to Maxwells laws it was not by way of his law of statics thus some have taken this as pointing to statics as something different and separate from electromechanics, Science has excepted that equilibrium is as universal as the GUT theorem which is why Einstein searched so long to identify the "weak" force. I remember a decade ago where I pointed to water cavitation having the same effect in electrical matters pointing to the comnbines loop dipole arrangement where cavitation occurs so that voltage can be a maximum at the dipole ends and where llewellen quickly pointed out that electricity does not work that way likening it to pushing to a new science. am totally unaware and nobody has pointed otherwise that the law of statics had a deinitive connection to Maxwells laws which points to radiators of a smaller volume and the identification of the weak force. You can gabble forever in knee jerk reaction to my postings but until you provide scientific technology to the subject to repudiate what I state you will remain a person that is wired diffgerently from other males that communicats in a strange way such gthat all meaning is totally obscurred in your search for like minded people thatg you can have a close relationship with in a like minded way. I for one are not one of that life style so get off my back. |

Well, Authru, it is obvious to the readers of this thread that of the two of us, this non engineer is the one who better comprehends Maxwell's work! This non engineer easily observes that Maxwell contributed the variable t (for time) to Gauss' equations. It is directly observable on page: http://www3.telus.net/nighttrainexpress/maxwell_1.htm at the paragraph heading (guess what?): "The Time-Dependant Wave Equation" This is a part of the curriculum of every EE who has attempted to educate you to this matter. Even this non engineer has formal training to this specific point. You now have been offered clear, specific, and demonstrable proof that your claims are spurious. However, I am full aware that we will revisit those invalid claims again as if you were never aware of this simple demonstration. 73's Richard Clark, KB7QHC |

David, I am so happy that Dr Davis of MIT has finaly been vindicated in the eyes of this group. It has taken years for the group to accept the static relationship with electromagnetics., I am also pleased that the present generation are using up to date material and not the books of 50 years ago where those taught at that time all was thought to be known and all change was resisted. Of course if this newsgroup wish to challenge the book excerpts that have been placed on this thread it would be very interesting including the deduction that a radiator can be any size, shape or elevation as long as it is in equilibrium.which is no small matter in designing small volume antennas using all four fourses that Maxwell and others clearly intended. Antennas belong to the present generation where the old timers are satified going to their graves convident that all is known while the present generation forgve ahead by the recognition of the trole of all four fouces which must be accounted for in any full analysis of the subject of radiation.. Now that Dr Davis has been vindicated old timers who are still mentally capable have the opportunity to be present in these very exciting times Nice weather here Davis so put aside that book you are writing and get outside where you can practice the praticle instead of being a talking head. Best regards Art. PS I look forward to your destruction of the text suplied on this thread since it opposes everything you have argued for during the last half dozen years. Hate to tell you but I did tell you so, many, many times. Eat some humble pie! |

Nothing wrong with that David the maximum boom length I got to was 80 feet and 13 elements but then had to back off to 60feet but they surely worked good but now I have got to old to handle the work required to maintain them. I was very surprized to hear you say that you were wired like Richard so don't ventue in Illinois! By the way did you get your four square antenna sorted out and is it working to your expectations? With respect to antenna height I have a feeling that height is not a question of wavelengths but a question of capacitive coupling to ground. I put the top band antenna up temporarily at a height of thirty feet and the the impedance settled on 50 ohms. I am now winterizing it so it gets thru the winter. It consists of just one element and a dish reflector but it will have to wait until next year before I feed it at the dish end, in the mean time it will just be fed at the centre I still hope for directionality even tho the rotor is at 30 feet but either way it will be interesting unless I move on to another project. I had to move away from the shoebox size of antenna, what I found out was it worked quite well for receiving but for transmit the eddy currents opposed each other thus preventing particle elevation so the volume is now double what it was but still small enough for the rotor to turn the top band form and light enough to easily put it on the tower Regards Art |

But except for receive, what good will that do you if you are 20db-30db down from a dipole due to the excessive inductive losses? I liken your setup to using a MW receiving loopstick as a transmit antenna.. :/ Not a whole heck of a lot of difference except yours is now a massive four shoe boxes in size. Mercy.. It's still puny considering the frequency. My MW receiving loop in this room is bigger than that. "A diamond 44 inches by 44 inches. And my MW loop would almost certainly outdo your design being as it is bigger and uses less turns of coil. "5" It's still a dummy load on a rotating stick... :/ I had to move away from the shoebox size of antenna, what I found out was it worked quite well for receiving but for transmit the eddy currents opposed each other thus preventing particle elevation so the volume is now double what it was but still small enough for the rotor to turn the top band form and light enough to easily put it on the tower So we have validation that your first antenna was a dud when used for transmitting! I'll alert the SPCA! But I'm afraid doubling the size of your dummy load on a stick is not going to pan out in the manner you would like. Even four shoe boxes worth of wound wire maketh not a good 160m antenna. Reboot and try again. |

I am also pleased that the present generation are using up to date
material and not the books of 50 years ago where those taught at that time all was thought to be known and all change was resisted. Art, I am not sure what you mean. This material has not changed in over 100 years. To quote from Ida's text, pp 731, 732: "Based on the inroduction of the displacement currents in Ampere's law, Maxwell predicted the existence of propagating waves, a prediction that was verified experimetally in 1888 by Heinrich Hertz. This prediction was based on the nature of the equations one obtains by using Maxwell's equations. We will show here that Maxwell's equations result, in general, in wave equations". This proof is shown in "Example 12.3", which is posted on my previously referenced web link: http://www3.telus.net/nighttrainexpress/maxwell_1.htm Unless you can show, by manipulation of Maxwell's equations, that it is possible to obtain a 2nd order partial differential equation where the independant variable is time; what is the point? I should also note that a course I took in electromagetics (About 1983) has an almost identical development of a wave equation. For reference the text is: "Introduction to Electromagnetic Fields", Clayton R Paul, and Syed A Nasar, published in 1982, ISBN 0-07-045884-7, pp 241 - 243 73, Frank. |

Frank, a couple of years ago I explained the inter weaving of Gauss law of statics with that of Maxwell. I twas this that met the most resistance of the this group. They seemed to see staics as something divorced from electromagnetics and thus one could not use equations of one with respect to the other. Thus when it was shown that the statics mathematics equated with Maxwells laws every body said that was not valid. The text you supplied made specific reference to this mathematical interplay whilst talking about quasi statics tho they never did the interface that I did. It was this rejection at the beginning that set the stage for years long rebuttle to the ideas that I put forward. To this day pretty much all are of the position that interfacing statics with dynamic fields or time varying currents was totally invalid which I put down to the education they received some 50 years ago. It was for that reason I was delighted to see a modern book that treated the subject with startling clarity. About 2 years ago a white paper was put out by two scientists that covers the Aether and its driving relationship to the Universe as well as revisiting the thinkings of the past with which they outlined questions that the present aproach seem to gloss over, as well as the revolving constituents( not foam) of the fast moving and revolving Aether and comparing present day notions of the Univers as opposed to their own findings. This paper is excellent and shows that many present day notions could be way of the mark Thus it pleases me that many are still questioning or reviewing the logic of electromagnetics including the more modern works of Planck in light of present day advances which certainly does not reflect the attitude of many in this group. In science and physics it is not a crime to challenge the thinkings of the past regardless if it may result in change as age of a theory does not present the idea of validity goes along with seniority As an aside modern books still refer to waves in electromagnetics but I feel this is a result of not understanding how radiation occurs and thus concluding it similar to magnetic lines of force where as I theorise it is the multi quantity of elevation and projection of charged particles with spin such that straight line trajectory is maintained , a must for transmission of radio communications by virtue of the "weak force" Regards Art |
