Enough bafflegab. As Sgt. Joe Friday used to say: "Just give us the facts". Best regards, Richard Harrison, KB5WZI Richard after all your denials regarding tipped antennas which you say is a myth we are now getting close to showing same via a computor program with optimizer which will show it is not a myth. what is the myth? they will do something different than a true vertical antenna, but probably nothing really useful. that antennas must be tipped for max vertical gain. if you want gain straight up then yes, you must tip the radiator, preferably by 90 degrees off vertical. I never thought David would finally acknowledge the mathematics even You haven't shown any mathematics to acknowledge... only bafflegab and hand waving. We then will see that the static particles that is part of Gauss is ejected from a radiator like an elevated frog, used for novelty reasons, show that radiatiation is by particles and not a wave will bring another antenna basher over to the Gaussian side. Then people will see how an eddy current applies spin to a departing particle such that it will attain a straight line trajectory for communication and the change over will become a flood and you will be left alone as an old man who cannot accept change While others are making small antennas now that it can be seen that a radiator can be any size shape or varied elevation as long as it is in equilibrium This being the start of this journey connecting a gaussian field in equilibrium to the mechanics of communication Art a perfect example of bafflegab, doubletalk, and downright nonsense... art can't really believe this and still be functional enough to type, so he must be still trying to pull our collective legs. David check it out to show the World why it is bafflegab, The same thing was stated when the Gaussian/Maxwell mathematics was given on this newsgroup. Be a hero and show the World why America is correct and I am in error From "Fields And Waves In Communication Electronics" Ramo, Whinnery, and Van Duzer, 2nd printing 1967... ppg 237 they have just stated the 4 classical Maxwell's equations in integral form and are explaining them in words. equation (1) is the surface integral of the vector displacement = the volume integral of the charge density.... which they explain as "Equation (1) is seen to be the familiar form of Gauss's law utilized so much in Chapter 2. Now that we are concerned with fields which are a function of time, the interpretation is that the electric flux flowing out of any closed surface _at a given instant_ is equal to the charge enclosed by the surface _at that instant_" (emphasis shown by _ x_ is THEIRS not mine). Now note art, that this shows that the classical Gauss's law that you are trying to add into the Maxwell equations is indeed already there. Also, as they point out it implicitly accounts for time variation without the need to add a specific time term to the equations. Your chance to make the July 4 a day to remember for American hams Ofcourse you can make an antenna where all lumped loads are cancelled to form an antenna in equilibrium but that would mean getting up from your couch and putting your six pack down. Not very likely Art six pack! ugh, i haven't touched a six pack in years, i much prefer real beer. is that your problem art, too many cheap six packs?? Wrong. The chapter gives NO mention of the role of static particles in radiation. Gauss never did apply an extension to his law of statics to reveal that a radiator can be any size , shape or elevation as long as the laws of equilibrium is in effect to make a dynamic field. This is clear indication that a radiator must be of a wavelength or more that is radiating which does not include the addition of a ground plane as part of the radiator. In addition, all laws only refer to distributed loads as a function of radiation and equilibrium and where lumped loads have no part in the equations. Equilibrium is also the datum proof where the charge within a conductor must be zero so that the law of Newton can be preserved ( action and reaction) By using the law of statics you find the importance of ":equilibrium" that Maxwell purloined as well as a new aproach to the sequences involved in radiation There is no question that the laws of Maxwell are not correct because each law he purloined included this stipulation as well as the extension to the gaussian law of statics which supplies the picture that Maxwell's laws are lacking. It is these same particles alluded in Gaussian law that are the true carriers of communication in radio where they are ejected from the radiator surface with spin provided by the opresence of eddy currents. Without the applied spin you cannot have a straight line trajectory. Ofcourse you can supply another reason why nature included particles in communication which would really thrill me to bits. But I am very pleased you are returning to written laws for proof even tho you misinterprete them. On the other hand you can verify that the requirement of equilibrium is preserved within Maxwells laws and thus antenna computer programs such that the tilted vertical is not removed from the subject of antennas. It was me that speculated that these same particles were neutrinos that are radio active and thus subject to decay that obtain a weak magnetic field from entry to the earth's magnetic field which are present in the billions per square metre on our native earth. It is also the wavelength data that supplies the information regarding the parallel tank circuit which is a pertinent part of all radiation. All these items I have found to intersect like a jigsaw puzzle that adequately describes the mechanics of radiation which hither to was unknown. Unless ofcourse you have studies that are contrary to the above. If you have, take them to the International conference on small antennas organised in San Diego U.S.next week by the American IEEE where you can drink in the applause of the World's experts Regards unwinantennas.com/ |
