"Christopher Cox" wrote in message ... Me, nah, I hold little or no knowledge on the subject of antenna's. I have lurked here for a very long time and have posted on occasion. I have a few pet projects on topic, an OCF with a vertical radiator and I am toying with a phase fed pair of quads. What prompted me to post was the tone of yours. I do not hold any great education, but know some very notable and brilliant people. I do O.k. for myself and have found that actions produce better results than words. Just thought that piece of wisdom applied here. Once you understand the difference between standing waves, (which has no real power itself but which stores the reactive VA power into that power which is is eventually dissipated in "radiation resitance" dissipating into free space as radiation power), and traveling waves, which do have real power that is also disspated into that same type of radiation power through the radiation resistance, an interesting question becomes "what is the nature of this so-called radiation resistance which dissipates the power of a forward wave or the stored power in a standing wave?". We feed power into the antenna as electric current and then it exits the antenna as radiation.. Maxwell's equations (in spite of what art theorizes) says that the power has been converted to an EM wave. So, electric current, which is not an EM wave consisting of photons and propagating into space, is converted into a different form of radiation energy that IS an EM and does consist of phtons and waves. When this conversion occurs and energy is transmitted into free space, we attempt to quantify this net loss to our generator with familiar terms, i.e. current or voltage dissipated into "radiation resistance". However, we all know there is no actual physical component known as a radiation resistor. Conceptualizing how this power conversion works goes back to maxwell: "why" is there a time varying EM magnetic and electric field (external waves and photons) generated by the flow of current? Well, it could be described as nature's tendency to maintain equilibrium. If a change is made to a conductor by putting a current through it, nature "objects" and fights back by setting up an EM wave that tends to cancel out the incoming current pulse. But no matter what, I will always easily have enough energy in my forcing function (current or voltage) to overcome nature's objection and send a net outflow of energy occuring as radiation theoretically equal to what I inputted. Art's unusual theories apparently have something to do with this same conversion of electric currents on the antenna to the radiated energy that propagates through space. Art believes he has made discoveries that augment the maxwell equations and solved the nystery as to how this power is converted from amps to radiation. He essentially takes advantage of the fact that scientists and hobbyists (at least on THIS board) have not done a good job conceptualizing what actually happens during the process of converting electric current from a generator to a radiated wave into free space. Our rather feeble invention of the radiation "resistor" helps us in the design of our antennas but it is not conceptually correct; a resistor is obviously dissipated as heat, not radiation (other than infrared heat). So how, physically does amps/volts in a conductor dissipates as radiation? That is a good question. And Art will give you a very UNacceptable answer to that question. No, the current particles do not fall out of the ends of the antenna and get levitated as galactic particles; this is the sort of thing, frankly, that you might hear from children. However, Arthur has been very persistent and I believe that over time persistance CAN overcome handicaps in both inteligence and education, at least on rare occaisions so I have tried to cooperate with Mr. Art up to now. That is, until *I read into the poor attitude and tone of his posings on this thread "Education". Indeed, he attacks even people such as myself who have attempted to encourage him. Now I see him for what he is...a simple crank of no relevance to the the scientific community out of his own choosing. He has no "small' 160m antenna on his tower (so he is a fibber), I interupt your post at this point only since you are expressing your views as in free speech but to be a fibber, a lier in other words is a deliberate untruth. At the moment I do not have the smallest antenna for 160M on my tower since the radiator is around 18 foot long and tipped at an angle to reflect what the computer states. I suppose I will have to make one that will fit into a 1 foot cubed carton to satisfy the term small. We have plenty of hams in this community plus repeaters so you can come yourself or ask a surragate to inspect on your behalf. It is a fold over tower so close examination is possible and I have all the necessary equipment to measure impedance or what have you. I also have on hand a loop style antenna for 20 M made on a hoola hoop, so I could convert that to 160M. On top of thatJohn has just rigged up Vincent's antenna that every body decries. If he were willing I could describe modifications for the same antenna constructed for a smaller size plus without the need for ground to avoid the comments applied to Vincents antenna . I have never met John but I believe him to be honest So I will supply him the details if he wants them and he can report results to you without pre inspection from myself. On the other hand I can build a small 160 M antenna and send it to hime by post office mail which he can play, with and report upon. Disagreement and suppression is one thing but a lier I am not! Either way I will now make a 160M small antenna incase it becomes desired. Yes I am very hurt by this barb and will work hard in full filling my side of what I have discussed. It may finish up a bit bigger than a foot since I have no idea how small it can be made but it will be small for shipping via the post office.It will be made of#22 wire so that it can also be tested for heat resistance, the bain of the EH antenna as well as Vincent's and many others. I haven't tested for that but see no problems as #22 should be able to handle normal use Art Unwin KB9MZ to him he doesn't know the difference between a standing wave and a traveling wave, is not familair with present models and their difficulties. If point zero is at the beginning, Mr. art is at -7 and he refuses to learn any tools that he needs to advance. I too would like a better conceptualization of why/what and how maxwells EM fields work and how the power conversion physically occurs on an antenna but for now I am stuck, along with everyone else, using the radiation resistance model. For all of its conceptual drawbacks, it works just fine mathematically. One key to better understanding (my opinion only) may be in more recent exotic physics models such as dark matter interactions with EM fields but that is way beyond any understanding I have at this point; that is why I previously took an interest in art's theory but which eventually went nowhere (too bad). I don't criticize him for that; he just needs to sharpen his tools a bit and take a completely different path if he is to succeed (but I predict he will not). Levitation of galactic particles in my opinion is not the path to success. AI4QJ |

Did you snag G3JMJ's loud signal this evening? I can load my 6m beam on 160m, but it doesn't work well at all. I use a slightly long inverted L with a series vacuum variable and nearly 6,000 feet of buried radials. There's a three inch short, tapped coil to ground at the feed point in order to match the antenna to the RG-213 I feed it with. The antenna isn't small and it isn't elegant. I'm willing to listen to your ideas about how I can equal the signal from that inverted L by using a much smaller antenna. Why don't you post information on such a creation? Dave K8MN |

As one example, your spew of needing a full wavelength radiator in order to be one with the force... What a crock of dung... I can whip you more with my little stick if you decide that you like it.. Pick one of your goofball theories and expound to your hearts delight. I bet this uneducated dumbass can rip it to shreds with only a small amount of pondering needed.
