In all the years that I have been on this group nobody has proved me wrong with respect to radiation. That's easy to understand. *You haven't said anything. *There's no substance to your "explanations". *I can't argue against an insubstantial fog or cloud, and neither can anyone else. *No models, no measurements, no tests, no numbers, no nothing. *Besides, it's not my position to prove that you are wrong. *It's your job to convince us that you're correct. *We pass judgement on your ideas, you do not. *Of course, you're always welcome to pass judgements on my qualifications to make such a judgement. If they had I would have apologized for the record.

Hmmm.... 24,000 postings. *Maybe I should find something more productive to do. For myself I can run all of these people out of town on antennas as they are all self perceived experts bestowing glory on them selves in retirement to supply the recognition they feel they earned in the past. Wow. *I'm not retired yet, but I'm not worried. *You would have no trouble running me out of town with your expertise on antennas. *I'm still learning and probably will never be an expert. *I read the NEC mailing list. *I dabble with EzNEC and 4NEC2. *I designm model, and build some rather odd microwave antennas. *I have two antenna related products to my name from about 20 years ago. *Not quite an expert but sufficiently functional to hold my own: http://802.11junk.com/jeffl/antennas/ Note: I did *NOT* design the commercial antennas shown. Find an expert for yourself and ask him the same questions that you ask of me. I only asked one question. *What do you mean by equalibrium and what is being balanced against what else. *No expert or beginner could answer that. *Only you can. My statements are nothing special and nor am I Actually, your statements initially appeared quite special to me. *I was serious when I asked what program you used to generate your rant. I couldn't believe that anyone intentionally wrote such a word salad. I suspected there was some software behind it. *I even attempted to duplicate the feat by hand (and failed). *Your statements are special to me for no better reason than I failed to mimick the style. -- # Jeff Liebermann 150 Felker St #D Santa Cruz CA 95060 # 831-336-2558 * * * * * #http://802.11junk.com* * * * * * * #http://www.LearnByDestroying.com* * * * * * * AE6KS Jeff Let us straighten out a few things about me that most know I am nowhere as clever or versatile in all the subjects that you mentioned. Frankly my present knoweledge is very limited. I had a heart attack, 5 bypasses plus a loss in memory.So that I could continue to live I chose radiation as a niche study for recovery. Ofcourse I will never recover fully. So basically I have tunnel vision built around the niche of radiation and antennas where I went back to first principles and started with Newton This process has lasted for several years, very slow progress but I have got to a point that my thoughts on antennas and radiation is so different from the books that I have to go back to the beginning with respect tp Newton and re evaluate with my peers. Yes I am seen as an idiot, very understandable but I am persistent in talking and discussing the initial point in radiation .From Newtons laws I deduce that current flow on a fractional wavelength antenna includes current flow thru the centre of a radiator. I am going right back to my new beginnings but the books do not say that! Soi I can't participate in the many diversions from the niche I have taken and thus ask for a similar focus from others. No sympathy or crying desired as I am comfortable and living a good life but even with tunnel vision I am determined to continue and participate in the route I have chosen as there is no alternative. Sooooo after more than a thousand posts based on the initial radiator and equilibrium I have been unable to make one step forward in a re evaluation of my journey. But I will never give up so you will have to live with that. All of this is old hat to most of the posters who give me hell and sometimes I respond in kind to new posters in a like manner which is wrong but it happens. So to sum up I am a simple man with tunnel vision in a single subject and no where as knoweledgable as other posters outside my field of choice. My very best regards Art Unwin KB9MZ....xg |

Antenna modeling (I suggest using 4NEC2) will keep you busy for another few months. Trying to reconcile theory, models, and reality will burn a few more months. However, when you're done, you will understand something about antennas and how they work. http://home.ict.nl/~arivoors/ Personally, I judge people by their willingness and ability to learn. That's what distinguished modern technological humans from a inanimate rock. I had a heart attack, 5 bypasses plus a loss in memory. In 2002, I just barely missed having a heart attack. I nearly passed out during the treadmill test. I celebrated the event with a triple bypass, which effectively rolled back my biological clock about 10 years. Best thing I ever did. No memory loss except from the anaesthetics used during surgery. Incidentally, I'm now 60.8 years old. Kinda sounds like you also had a stroke. You're lucky to be alive. My father had a stroke in 1986 and did not do very well afterwards. So that I could continue to live I chose radiation as a niche study for recovery. Fine, but I question the methods you call "study". It's considered good form to gather your evidence first, and then supply your conclusions, not the reverse order. Of course I will never recover fully. Neither will I. I'm still collecting medical problems. Man was meant to live for about 25 years. Anything beyond that is a free ride. So basically I have tunnel vision built around the niche of radiation and antennas where I went back to first principles and started with Newton This process has lasted for several years, very slow progress but I have got to a point that my thoughts on antennas and radiation is so different from the books that I have to go back to the beginning with respect tp Newton and re evaluate with my peers. Radio and antennas are built of physics. However, it's not Newtonian physics, but electrodynamics as in Maxwell's Equations. Have you studied those? They're quite different from Newton's equations, which a sometimes called "classical mechanics". (Note: It's not easy. Just decoding the notation is a major challenge). http://en.wikipedia.org/wiki/Maxwell's_equations Yes I am seen as an idiot, very understandable but I am persistent in talking and discussing the initial point in radiation . You make an attempt at understanding. An idiot doesn't even try. From Newtons laws I deduce that current flow on a fractional wavelength antenna includes current flow thru the centre of a radiator. Which of Newton's laws? What equations or thought experiment resulted in this deduction? How do you reconcile your conclusion with the common assumption that RF current flows on the outside of a conductor? I am going right back to my new beginnings but the books do not say that! For good reason. You're wrong and your unspecified books are correct. So I can't participate in the many diversions from the niche I have taken and thus ask for a similar focus from others. Yes you can. You can take it one step at a time. No need to jump directly from Newton to skin effect. Just walk me through your logic. No sympathy or crying desired as I am comfortable and living a good life but even with tunnel vision I am determined to continue and participate in the route I have chosen as there is no alternative. By contrast, I'm willing to throw out everything I have learned and presume to be correct, if any of it can be proven or demonstrated wrong. I hold absolutely nothing (except my bank balance) as sacred, and consider everything subject to suspicion and debate. If you are permanently attached to your pet theory, you effectively refuse to accept input or criticism. Therefore, you have stopped learning and are starting to resemble the previously mentioned inanimate rock. For example, did you know that the direction one counts causes the final count to vary? A simple example is counting the number of fingers on both hands. Start from one end counting 1,2,3,4,5,6... and ending in 10, which appears to be the correct count. Yet counting fingers downward results in 10, 9, 8, 7, 6, plus 5 more makes 11. Surprise, you have 11 fingers. Like I said, nothing is sacred. Sooooo after more than a thousand posts based on the initial radiator and equilibrium I have been unable to make one step forward in a re evaluation of my journey. But I will never give up so you will have to live with that. All of this is old hat to most of the posters who give me hell and sometimes I respond in kind to new posters in a like manner which is wrong but it happens. So to sum up I am a simple man with tunnel vision in a single subject and no where as knoweledgable as other posters outside my field of choice. Suit yourself. As you make your bed, so shall you sleep in it. Repetition of incorrect gibberish only works in politics, not in science and technology. My very best regards Art Unwin KB9MZ....xg Good luck.

Now let me analyze this and see ... 1) He is dealing with matters/effects/theories/speculations which universities/physicists/scholars/mathematician/theorists/amateurs/etc. are working/speculating/experimenting on. 2) Usually actions/effects/affects/phenomenon are observed before it even occurs to anyone to design an equation or formula about it. 3) Some speculations will, obviously, be incorrect or partially correct and need rethinking, or scraped and new ones advanced. 4) Etc., etc. Nope, you are quite correct ... he hasn't. However, to some, the reason(s) will be quite obvious; for others, it may take a bit longer ... Regards, JS |

Oh David emotion has got such a hold on you that you can't think straight. In one of the management classes I took they said if an employee can not be calmed always protect the path to exit. Medics say that anger or emotion can shut down the route to the house of logic in the human brain such that logic cannot come into being. Seams like the human brain is subdivided into physical block of knoweledge This explains why a baby learnes to walk quicker than a grown man with experience and tangled information routes.. You need a 2 by 4 to shake things up Think about that Dave Still your friend Art |
