This is hardly a monumental observation - except when it upsets the horse cart of celebrity. You wasted your time, Richard. Everyone should already know that there are received reflected waves of all different frequencies on a traveling wave antenna. However, they can all be completely ignored since we are only interested in the one frequency on which we are transmitting *and* in the direction to which we are transmitting. Introducing all the other extraneous frequencies and directions that exist is an act of desperation. In particular, we are not interested in the received standing waves that are incident upon our terminated rhombic when they are coming from the side or back of the antenna. That they exist proves absolutely nothing of value. Hi Dan, I want you to take this quote above and observe that it offers nothing of data, and certainly says nothing of any model (except by the slightest of inference), and there is nothing of a practical measurement. It does touch on the gray matter you aspire to keep active in the game, but only to recite homilies that do not attend the discussion. One could as easily demand that Ohm's law describes conduction, but say nothing about current, voltage, or resistance. Yes, all very true about Ohm, but hardly dismissive of prior models presented or their data that they deliver (by whatever means), nor how the sum of these typical engineering considerations fails to conform to the logic of Cecil's proposed argument. By the points: !. different frequencies is not an issue, only one has ever been expressed; 2. direction is not an issue, excitation is by degree only, nothing changes the energy distribution in relative phases nor period; 3. termination was not my issue (although I conformed to Cecil's demand that it should be) as I had already accounted for it; 4. they (Standing Waves) exist may be nothing of value, but only for a desperate celebrity who discounts his argument, impeaches his models and disinherits their data. If you still find EZNEC a poor mechanism to support an argument through its means of presenting what you might call suspect data, then the quoted response to my posting above, has to be light years further from a rational conclusive demonstration. ;-) 73's Richard Clark, KB7QHC |
