Richard I have a personal preference for discone and log periodic antennae for the wide frequency coverage. Which is kind of why I suggested the interpretation of Art's design that I did. It is difficult to picture some of his designs from the descriptions at times. snip Mike One thing you need to understand is that Art has no designs. Even his patent applications contain the written and drawn versions of bafflegab. He has never designed, never built, and never tested anything that performs like his claims. All he does is pontificate. And he ain't the pontiff. tom K0TAR |

From photographs I have seen, they look to be resonant somewhere in the current VHF band, not that it was of any consequence as the experiments were only conducted across about 8 feet. Could have just been magnetic induction coupling from the transmitting and receiving coils... Now there's an idea for a novel antenna. Hi Mike, Quite true as to band and dimensions. However, those are balanced (dare I say in equilibrium?) in comparison to all capacitor and no inductance with currents bucking each other. 73's Richard Clark, KB7QHC |

Jaro He head not empty. The truth in he claim is quite obvious for all to see. If old man Unwin had an antenna that actually performed with even half the gusto of his claims, he would not have to resort to pseudo science mumbo gumbo in order to try to convince people that he has. In fact, he wouldn't really have to explain a thing. He could just mount it on a pike and let it do the talking. But it's hard to claim radiation efficiency of 100% when you are using a contra wound dummy load. He might beat out Mike's light bulb dummy load, but by only a slim margin. My calculations show that any minor increase over the efficiency of a coax fed light bulb are not sufficient to cause the delusions of grandeur which seem to possess Unwin. So what say Jaroslav, o man o vision.. Can *you* prove that Art has designed, built and tested any miracle whip that performs as he claims? Hold my breath not, sayeth Yoda.. Chortle.. |

****** tear on dotted line and return ****************
Have we gotten any practical contra-example to the simple dipole being 100% efficient? You know, a real design that describes frequency, length, and width of wire? Well, no response as far as I can tell which means that Art cannot produce a simple description of wire gauge, wire length, and wire excited frequency (admittedly a pretty difficult demand to place upon a guru) for an antenna that is in equilibrium and displays efficiency better than the 100% which is commonly available from a simple dipole.

: From the Laotse Tao te king: "More words count less." Hmm, on the subject of Chinese kings... "A king was pleased with the help of a warrior, and asked what the warrior would take as reward. The warrior said, a grain of rice on the first square of a chessboard, on one day, two on a second square, and the second day, until the board was used up. The story goes that with every doubling to 64 squares, the warrior bankrupted the king within two months." But I ask: how much rice CAN you fit on a chessboard? I wonder if Art might recognise that little homily, and my question, as a parallel to the effect that an antenna need not pointlessly strive for 100% efficiency, but instead to get a practical and useful propagation or low- noise collection. If you really want a tiny antenna, never mind inefficiency, catch what you can and use it. Ok, too many words from me. |
