You have to present some examples of things that actually work well before you are considered credible. So far you have not done any of the above. The Chronicles of Arthur Unwin. :/ Delusions of grandeur induced by abuse and misuse of antenna modeling programs. Excessive adult beverage consumption may also be an issue, but I couldn't really say being as I can't give him a breathalyzer test over the internet... Heck, I think more than a few of the common programs have "optimization" routines. Big deal. I know the freeware MMANA does.. And having played with it a bit, I know you have to take the results with a grain of salt, and often the results were worse than what I would come up with manually. ![]() Say optimizing a yagi.. I've seen some fairly peculiar and below par results using the optimization in that program. Art's blind trust is rather peculiar. :/ Not to mention some of his peculiar theories and notions. IE: if the pattern of an antenna displays an isotropic pattern, how in the heck are you going to have large amounts of gain? The gain would be near zero if using isotropic antenna as the reference. Not 32 dbi or whatever number he came up with. In order to have gain in any direction, a null must form in some other direction. No free lunch. Sorry. Of course, Art seems to confuse efficiency and gain, but that's a chapter for another day. Art generally ignores efficiency. In his world, equilibrium, neutrinos, and solar fairy dust particles with levitating vortex swirls cause efficiency issues to vanish into thin air. If the vortex swirls start to resemble what you would see off a Boeing 757 on a moist cloudy day, you have total equilibrium and obvious 100% efficiency and 87 dbi gain in all directions. Tell Jethro to fix the brakes on the truck. We may be moving soon. ![]() Say as when using an A/C fan motors worth of thin wire wound on a short stick of PVC and supposedly operated on 160m.. ![]() But even Art himself claims to almost never actually use the transmitter in his rig. Being as even a stick of wound wire can receive halfway well on the low bands, we have a new miracle! Never mind that some guy tried the same thing about 85 years ago I'm sure.. :/ It doesn't work any better now than it did then. Back to the drawing board for prior Art.. No transmit tests or comparison with known benchmarks are required in the world of Art. The masters sayeth, so it must be true! Woe to the non believers! They knoweth not what they do or say! They have no equilibrium! Call the patent office, and get the lawyers on the phone! Load up the truck, we're moving to Beverly Hills. ![]() Did Jethro ever fix the brakes? In the dark recesses of Art's brain, he applied the theory of reciprocity to this antenna. It receives fairly well, so it surely must transmit in a like manner. If only the world were fair. Next week.. If you run over a neutrino with a Goodyear Accutread tire, will a puncture occur? The answer to this question and many others on the next installment of Art's Chronicles. |
