Do we blame Gauss for the original poor performance? Does this validate Art's concept of static electromechanical waves? Art, if this is a typo (electromechanical waves), then how many other typos inhabit your descriptions that corrupt your truths that come out so tarnished? If we have to sit through another rendition of Hearts and Flowers about us kicking cripples, stealing from blind newsboys, defrauding widows, and getting our rewards taken away from us in an after-life; then maybe you should get a season ticket to the new moderated group where those soap opera tunes can be sung in their castrati choir. 73's Richard Clark, KB7QHC Hi Richard, I was not really serious, but at least wanted to demonstrate that a simple 2 element array outperformed the fictitious antenna which must be machined to within +/- 1 micro-inch. I assume it is some kind of joke, and particularly liked the description of orbiting helium nuclei; also the presence of beta particles. The elements must be partially radio-active. 73, Frank (VE6CB)- Hide quoted text - - Show quoted text - Frank, choose your friends! Alpha and Beta were the first two letters of the alphabet, I do not wish to represent myself as a physicist. On the multi decimal figures they are computor derived and I do not feel it to be my place to manipulate figures. On the ficticious three element beam it was clearly laid out as a sample that in no way was an extension of a Yagi beamm where all elements were resonant and not planar or parasitic in form. Tt clearly laid out the polarity of the gains mentioned which by the way you did not do. In fact I don't know what you did or where your figures originated from. The sample beam was drawn up purely to demonstrate the dexterity of positions plus the multi resonance and it was accompanied by the process from whence the dimensions came from, which this group in its entirety stated as implausable some weeks ago. As an adder I gave swr curves together with gain curves to demonstrate the absense of parasitics which for a yagi demands choices of desirebles ( there is a whole chaptor in the ARRL handbook about this problem.) As an aside I also included in the array an element which was not only at an angle relative to that around it but also of a length unrelated to a half wave length. Now you obviously are not aware of the vagrances of antennas otherwise you would not have replied like you did with an example missing details of measurement, phase and to any point that perhaps you were trying to make. I could have drawn a high gain antenna of half the length of a yagi with the same gain but that would have strayed from what I was trying to emphasise i.e. an advance in science.. You are obviously out of touch with respect to antennas by what you write as are others who are declaring their lack of knoweledge by what they say. What goes around comes around and you will notice that nobody has faulted the theory espoused for the array other than your word of ficticious which you never explained. Give me something for the record please.Do you have a high school diploma? Art Art- Hide quoted text - - Show quoted text - Frank, On the net iswa free book on waves and antennas by a professer at Rutgers University In chapter 21 he plays with a clustr element that first came about some 60 years ago. In book the array was changed somewhat to provide an array from which all the desirables could be determined. This 60 year old array was solved in various ways but today even more than 60 yearsof existance did anybody realize the connection to Gaussian law of statics when the addition of time is added to the law. I am the first to make that distinction from which a whole new antenna technology will arise. Now you refer to Richard for some sort of support but he doesn't have a docterate, he doesn't have a masters and he certainly does not have a degree in engineering. Now I know many men in San Fransisco do swear by him as would his close friends would when he dons his meshnet tights and shows of his degrees to them which is a 90 degree piroett in front of them but the fact is that he did attend some university programs as a guest since he is knoweledgable about Shakesapeare and dancing.Be carefull of your choice of friends Art |
