Three short simple questions about antennas.
Hi Art
it is my experience that people with the greatest mastery of the queen's english use it with great effect to deflect questions and to avoid giving straight answers,and to change the subject without you realising that they have done so. Politicians and Richards 1and 2 being good examples. What i have witnessed going on in your last couple of threads has not led me to change my opinion. Your tenacity and conviction in the face of the opposition on this group is admirable. Stick to your guns, for what it is worth my money is on you. Jaro. |

Mark you should have no room for complaints. I offered you unhindered access
to my work including the computor programing system which I would purchase at my own expense together with the programing I used to substantiated my findings. You refused that offer prefering to stay with the pack and ridicule all. You have had access to the patent write ups many times as they have been brought forward many times by members to serve at a ridicule point and all you had to do was to click on what was supplied. They also found a very old page that I had describing the loop/dipole antenna together with the drawings and you are still complaining. I have personally informed you that EZNEC was not a suitable vehicle for this work but you proceded on the point that you were proficient in any sort of computor programing, and you are still complaining ,and now you bring up a drawing that you say you put before me even tho you had the option of looking at the many drawings available. I just looked at the drawing that you proffer and I defy anybody to look at that and know what it represents. Time and time again I tried to make peace with you but you chose to tag along with those who have attacked many contributors in the past since they have a long winning record in ousting many others. You decided on your nest a long time ago so you really have no reason to complain as you still have your cohorts around you that tend to belittle all. Your crying now falls on deaf ears. Nuff said 'Good day' I think he said Art "Mark Keith" wrote in message om... (jaroslav lipka) wrote in message g'day Keith When it comes to modeling what you leave out is just as important as what you put in, some times more so. My money is still on Art. Jaro. To do what? As far as modeling, I modeled exactly what he told me to. He ok'ed the diagram of the antenna. As a matter of fact I still have it on my server. http://web.wt.net/~nm5k/loopole.jpg MK |

Mark you should have no room for complaints. Who's complaining? I could really give a rats ass about you or your antenna.... I offered you unhindered access to my work including the computor programing system which I would purchase at my own expense together with the programing I used to substantiated my findings. Why do I need yours? I have many programs. They all pretty much do the same thing. You refused that offer prefering to stay with the pack and ridicule all. I only ridicule horsecrap Art. I asked the guy a simple frigging question.. WTF are you going to do, that his money is on? So far, he hasn't answered. I don't think he knows. If that is ridicule,that just too damn bad isn't it...What a whiny ass old fart you are, Art. You have had access to the patent write ups many times as they have been brought forward many times by members to serve at a ridicule point and all you had to do was to click on what was supplied. Are you talking about the rube goldberg looking thing? I've seen it... They also found a very old page that I had describing the loop/dipole antenna together with the drawings and you are still complaining. Complaining my ass. I have personally informed you that EZNEC was not a suitable vehicle for this work Bull****, Art. Plain and simple. but you proceded on the point that you were proficient in any sort of computor programing, They pretty much all use the same basic engines... and you are still complaining , Again, bite me Art. Complaining my ass. You just wait till I'm REALLY complaining you frigging fool. Don't screw with me. You **** me off, and I WILL be your worst frigging nightmare. I'll stick to you like dried turd particles on a baby's ass. Everything you say that is BS, I will comment on. Is that what you really want? As is it, I only comment on about 50% of it... and now you bring up a drawing that you say you put before me even tho you had the option of looking at the many drawings available. Art, you frigging fool, that is the picture from the modeling program itself. I sent it to you. You looked at it, and ok'ed it. I just looked at the drawing that you proffer and I defy anybody to look at that and know what it represents. Jeeze...What a frigging idiot you are, Art. Time and time again I tried to make peace with you but you chose to tag along with those who have attacked many contributors in the past since they have a long winning record in ousting many others. No Art. I won't kiss your ass. Tag along? Tag along with whom? WTF are you talking about? You decided on your nest a long time ago My nest? Crap.... so you really have no reason to complain as you still have your cohorts around you that tend to belittle all. Bite me Art. I could give a flying #$%^ what the others say or think. That includes you, you old fart. Your crying now falls on deaf ears. You'll think crying... Nuff said Yea, I think so.... 'Good day' I think he said Art Yea, later Art. MK |
"aunwin" wrote in message I have personally informed
you that EZNEC was not a suitable vehicle for this work but you proceded on the point that you were proficient in any sort of computor programing, BTW, since your memory is suspect, and seems to be failing...I did NOT use EZNEC. I only have the eznec demo, and the demo did not have enough segments to be able to model that with reliable results. "I think it would have been good enough for gov work though." As far as programming, what does that have to do with anything? I "program" flight sim software. Not antenna modeling software. What does my programming abilities have to do with your antenna, or the modeling of it? Thats easy...None. MK |

On reflection, I guess I got a little testy with Art. But he provoked me... But I do apologize for the somewhat nasty comments.. But, I do not suffer fools well. Anyone can look in google, and read the threads themselves. When I modeled that antenna, I nearly had to jump through hoops to get an accurate description, but I finally got his ok, as all can read. I modeled the thing exactly as he described, eventually, and the results did not agree with his ideas. What was his only comment to the whole ordeal and modeling exercise? "quote" "Good for you Mark! You have done a lot of good work on it' and you got so close. So we put you down for " it won't work as stated,"Your opinion is as good as any and you are not beating around the bush or hedging Have a great week end Art" Unquote... Note the "you came so close"....ONLY if I had results that agreed with his, whole the results have been final. The results of the modeling did not suit him, so he had no further comment. I see no claim above that I "butchered" the model or diagram of the 20m dipole involved. Only in the beginning, when I doubled the size to 40m. This was before his thread "a tutorial", so I had no way of knowing what band he wanted. The links to the threads involved can be read at these URLS. They link to my search, but will read the whole threads. http://groups.google.com/groups?hl=e...Db%26a s_mind 3D12%26as_minm%3D7%26as_miny%3D2002%26as_maxd%3D18 %26as_maxm%3D9%26as_maxy%3D2002%26safe%3Dimages http://groups.google.com/groups?hl=e...Db%26a s_mind 3D12%26as_minm%3D7%26as_miny%3D2002%26as_maxd%3D18 %26as_maxm%3D9%26as_maxy%3D2002%26safe%3Dimages http://groups.google.com/groups?hl=e...Db%26a s_mind 3D12%26as_minm%3D7%26as_miny%3D2002%26as_maxd%3D18 %26as_maxm%3D9%26as_maxy%3D2002%26safe%3Dimages Art, if two years later, you don't like the model, do it yourself, and post the results for inspection.

"Here he (Moxon) showed a combination loop dipole that could be used for at least three bands. What was important to me was the importance of coupling which brings up the issue that no where does it say that all antennas must be based around wavelength and the accompanying series circuit." Just as surely, Moxon does not say that his loop and dipole antenna is aperiodic. Every piece of wire has a frequency of first resonance where its distributed inductance and distributed capacitance have equal reactance magnitudes. At this frequency, these reactances of opposite types exactly cancel leaving only resistance to oppose antenna current. Either side of resonance, antenna impedance rises sharply due to reactance. Radiation resistance causes the Q to be low as compared to an unloaded LC tuned circuit. An antenna may have a Q in the teens while an unloaded LC circuit can have a Q in the hundreds. Moxon may have assumed his readers understood such antennas as his were resonant and sensitive to frequency (wavelength). I don`t have Moxon`s diagram but from Art`s description of long ago, his version conjoins loop and center-fed dipole rod. The feedline connects directly to the loop or through a variable capacitor. In either case, coupling seems complete to me. I guess Moxon didn`t motorize the capacitance in his T / gamma matching system, so Art patented it. Best regards, Richard Harrison, KB5WZI |

Hi Jaro, I presume by this you haven't any idea how it could be proven yourself? G'day Richard Why am i not surprised you jumped in. As i have stated before i know very little about Antenna's, but i do consider myself a reasonable judge of people. I first came across this group about two years ago and what caught my attention then was a post you made where you were attempting to ridicule where Art had sugested putting a feed on an Antenna (i believe it was a Moxon)and in a later post Ian White confirmed it was the correct position. Since then i have seen you and one or two others miss no opportunity to attack and denigrate his posts and him personaly. Over the same period i have seen Art gaining more and more confidence with every post he made culminating in his last post to this thread combined with his posts to the Q thread where he was saying in my opinion, He knows what he has got and he knows what it can do and what is more he can prove it,so he does not need to take any more crap from you. You ask for facts and figures,why should he supply them when judging from your previous posts you have already decided whatever he claims he is wrong. The temperature here is 40c and is forecast to stay the same for another three days,is it possible all this hot air is eminating from your direction across the Pacific. Jaro. |

Hi Jaro, That is a presumption not supported by any evidence much less observable in your correspondence. You respond as a social critic often, and to take me to task for that same office exposes your having little talent for it. I must admit it does not come naturaly, I do tend to struggle a bit. As a social critic, you should examine the quality of your education closer. For instance, English is one of the few, if not only, languages that distinguishes and capitalizes the first person pronoun - I. Fair dinkum! To a social examiner, the persistent usage of the lower case i would suggest problems of either self perception, or over exposure to the works of e.e. cummings. None of the above, just put it down to a basic education and a lack of observation when reading other posts, but I thank you for "your" observation and I assure you I will get it right in future. Have checked out e.e. cummings but I'm not one for poetry thanks. Your support of Art certainly serves to relieve your boredom - one of those decadent Old World problems of ennui? You are right again, boredom is a killer, Jaro, please don't let this dissuade you from more entries here, their quality heightens the contrast to real participation. Thank you for your invitation, I am happy to continue to post but as I pointed out it does not come naturaly, so I will have to ration them out. Is that ok with you?. Let's just say your prejudice has the same weight as Art's proofs you fail to comprehend - could we say Ætherial Oh dear! thats the second time I have had to check my dictionary in this post. My interpretation of that is a bit "Airy Fairy" G'Day Richard I limit myself to learning one new word a day, so if you decide to reply please don't over do it, thanks. Jaro. |

(Mark Keith) wrote in message . com... Art, Just quit all this whining. Whine, whine, whine...Thats what gets my goat...And this whining involved me....MK G'day Keith don't know where you get the idea that Art's whining from, Have they kept you stored in a closet? He whines about the NG, and it's participants. He whines about his supposed lack of edjucashun. He whines about his medical problems. He whines about antenna modeling programs that he doesn't even own or use. He whines because no one seems to take his antenna too seriously. He just whines.... but from the way i read his last post he write's like someone who knows exactly what he has got, and what it will do and is confident that when the time comes he can prove it,and to answer your question "that" is what my money is on. I wouldn't hold your breath. You, "or he" will die before he decides what he has. He grabs at different straws about once every two months trying to "explain" what he has. It's this constant straw grabbing that attracts the attention of many. Oh sure, he "knows" what he has, but whether what he has conforms with reality and the laws of modern science is another thing entirely. I've been watching him talk about the antenna for 2-3-4 years, and I still see no indication he has ever actually built one for current use, besides his little 160m thing, which seems somewhat unrelated to what I modeled. He says he used to run one at some point in time....But even making something and using it, does not automatically mean his description of it's operation is factual. What FIRST got me to model his "loopole" was his claim that you would see collinear gains with this device. That was the first thing I had to shoot down...Landed with a might thud it did...His comments of that type ended quickly. But he won't believe my claims that his loop/cap device is nothing but a simple matching device. "others descriptions of linear resonator devices non-withstanding" I'm not totally sold on that theory as far as getting a match in itself. His views of "coupling" are very distorted in my opinion. That why I asked him a few days ago to describe coupling. He declined to answer... To put it plainly far from whining i get the impression he was telling you to "go take a jump", Jaro. He wants to tell nearly everyone on here to take a jump. Doesn't bother me...MK |

"What FIRST got me to model his "loopole" was his claim that you could get collinear gain with his device." Art`s unexplained claims amazed me so I jotted them down. 1) More gain than other antennas 2) Useable SWR`s also 3) Rotatable with under 200 ft turning space 4) No heavier than the lightest antennas on the market 5) Can be made wide banded 6) Can be made narrow banded 7) Can be made variable frequency operative 8) Can be automated for maximum gain 9) Can be automated for best SWR As I recall, all those claims come from one posting but the list may be incomplete. I responded that the posting seemed an advert. Art seems to ignore in his "loopole" that tight coupling means resonances in the loop and pole are interactive, not independent. Art should produce some numbers to back gain and SWR superiority claims. Best regards, Richard Harrison, KB5WZI |
