Well Cecil what ever you do do not use the word efficiency,
just use the ratio between X and Y fully stating what X is and Y is. This way the word efficiency need not be used for a baseless augument. I am very pleased by the way, that you are not attempting to explain anything new but just educating the masses on what is already known, and forgotton by the way, and re presenting the facts of nature in a way everybody can understand that leaves no room for argument. If you do find something new present it in such a way that the Gurus can respond in such a way that it is their idea or they knew it all along but have just been to busy to write it up. Send your paper again with the footnote that their previous response and leadership is what you built upon and which you need further assistance from them. It should then get printed in a couple of months and your name printed as a foot note. I saw a aeroplane crash data box a short time ago only to find that is not a black "box" as previously stated. Ever thought of designing a better black "box" to put it in and then become famous in your own mind? The previous one made of cardboard just didn't work out when things became all wet.

I now accept that all is now known about antennas except the really deep things that Cecil is so bravely pushing on with where I failed. One slight correction, Art. Because of the similarity between light and radiated EM waves, most things about antennas are known, at least to the limit of the models to handle reality. However, it appears to me that some things have been overlooked when the coherent EM waves are confined to a one-dimensional transmission line. Those things that have been overlooked are what I am pursuing and as far as I can determine, they happen only inside a transmission line or at a thin-film non-reflective surface using coherent light waves. That's what makes it special. That is not to conclude that you haven't discovered something special, just that my focus is Z0-match points inside transmission lines and non-glare thin-film coatings involving orthogonal coherent light. |

Roy Lewallen, W7EL wrote: Just playing devels advocate here, but, as you state "If you put X watts into one antenna and extract Y watts from an antenna coupled to it, and measure the efficiency of the "transformer" the same way as you did the conventional transformer, you'll find it has lousy efficiency.", does that refer to the 377 ohms (or so) free space coupling impedence, or could that effeciency be improved by having the antenna's matched radiation resistance approach that 377 ohms? (I.E. max transfer of power is at Z0 (in) matches Z0(out)! or, is this academic for this? Perhaps, better for Dr. Shorza Gitchigoumi of CQ fame, or Larson E. Rapp of ARRL fame (both with bad habit of only presenting articles in the 4th month of the year in their respective publications) ! But, I'd thought I had better ask! Jim NN7K "Roy Lewallen" wrote in message ... I hope you'll pardon me for amplifying this a little. If you put X watts into the primary of a transformer and extract Y watts from the secondary, the efficiency is Y/X by definition. If you put X watts into one antenna and extract Y watts from an antenna coupled to it, and measure the efficiency of the "transformer" the same way as you did the conventional transformer, you'll find it has lousy efficiency. Why? Because a goodly fraction of the power you applied to the "primary" antenna never gets to the "secondary" antenna because it's radiated instead. As far as the "secondary" is concerned, it might as well have been converted to heat. If you look at the impedance of the "primary" antenna, you'll find an excess of resistance -- just enough, in fact, to account for the "lost" (radiated) power. This isn't a statement about how well coupled antennas function as antennas, whose purpose is to radiate after all. It's a statement about how well they function as a transformer. Poorly.

Mark,
A couple of correction before I completely move away from my antenna Yes I did not got to University, nor did I have a normal schooling in my childhood since the London was undergoing changes forced upon it by a man named Hitler However I do believe that I have gained an education of sorts since I managed to meet all academic requirements as a P.E. I came to the States because of offers that I received (expenses paid)My family sold up after three months and followed me when it was realised that I ccould not last for ever on fast food. Since I workrd for G.E. as a Senior engineer upto retirement I now lead a comfortable life. The patents that I wrote up on antennas reflectes my inexperience with the subject but the present write up should be more readable when it is finally accepted by the P.T.O. As far as actually making my antennas it would be foolhardy not to, including double checking with computor analysis together with academic review from first principles. All of the above was done as a hobby to suit myself only as a 'lifeline' activity after a serious illness. Enough said... my present project is a 'micky' mouse tuner. Best Regards Art (Mark Keith) wrote in message om... (Art Unwin KB9MZ) wrote in message Mark, Put the whole antenna idea aside The thing could not possibly work, my activity is a total illusion. If anything new comes along, which is highly unlikely since all is known,do you really believe it would be the likes of me to find it? Many useful inventions have come from people that on the surface, you would think are surely dumbasses in their fields due to lack of training. I can think of many right off the top of my head. I don't think Bill Lear had too much school and training, but he seemed to do ok as one example. I think he invented the 8 track, along with a few other aviation related patents. "I think anyway".. Not to mention cobbling together the jet airplane which is quite common at airports these days. So this "poor dumb ole Art" crap is not going to fly far with me. If you feel the antenna would work, I think you should build it. I would ignore everything everyone says. BUT! I wouldn't presume to flog others for their lack of "vision", just because something you don't even use or seemd to have built in real life is not readily accepted as practical. If you think it's a great idea, use it. The end performance will tell the true story. As an example, note the "EH" guy. Personally, I think he's on a misguided turd hunt, but at least he's got the nads to actually build the crazy looking things. And this eventually lets others compare them to tell the true story. Unfortunately, his antenna seems to be primarily a feedline hanging device. It supports the feedline, which is the "real" antenna and does the bulk of the radiating. I think a pully or other hanging device would be about as efficient overall. :/ MK |

We took a three-week N European Cruise from Dover to LeHavre, Oslo, Copenhagen, Rostock, Gdansk, Tallinn, St. Petersburg, Helsinki, Stockholm and back to London. One of the best cruises we've had. Had a lot of fun with the GPS. It still worked while in Eastern Longitudes. I got Ian's phone number from Roy, but any time I was available to call him was an inappropriate time to call him, so I missed him. Roy emailed Reg to have him email me his address, and I sent him two emails asking for it, but he never answered. Was hoping to be able to meet them both while in England, but better luck next time. I hope you're drooling, Tom. Walt, W2DU |
