This is getting dangerously close to a you-cain't-prove-it-ain't type of argument. 73, Tom Donaly, KA6RUH |

See http://web2.iadfw.net/uthman/elements_of_body.html for a pretty good list. -- Jim Pennino Remove -spam-sux to reply. |

There was a running gag over in rec.audio.high-end a few years ago, about the ultimate speaker cables: mercury-filled surgical rubber tubing. That's exactly what I thought of when I saw this subject line. For those who missed it in 1987: http://tinyurl.com/ywjd8 My favorite response in that 17-year-old thread: I can see the review by Anthony Cordesman now: "This wire lends a liquid transparency to strings. The fluid quality of horns has to be heard to be believed. There is a silvery quality to the brass, with no sign of the hard-edged, coppery sound normally associated with speaker cable... 73, John NU3E |

A fine example of what Herb Caen, in the SF Chronicle, used to refer to as "the prismatic luminescence school of wine critics". |

Has anyone actually tried it yet?
Considering only a drop in a neon sign or vapor lamp makes the difference between not working at radiating a tremendous amount of energy, it's worth a few careful experiments. |

Advertizing Yagi "Neon" tube arrays as STEALTH antennas. Your are beating my own inventions of crazy antenna designs. Won't work too well actually, at least not for reception, because the irregular flickering of the plasma will induce a very large amount of noise. w. -- On the Internet nobody knows that I am a dog. |

I was not suggesting using an entire neon sign or vapor lamp as an
antenna. I was pointing out 'the presence of a tiny drop of mercury' is required for these devices to work. A catalyst perhaps? Therefore, let's say our antenna was a piece of wire or metal tubing was inside another non-metallic tube, and a small amount of mercury was also in the tube. Would the mercury have a desirable effect? Remember, we're not talking about tremendous amounts of power here. Your typical 4' fluorescent tube is a 32 to 40 watt device, and there are much lower output tubes as well. The primary excitation inside the tube is due to high voltage, not high current. So, it may not be too far fetched to build a few designs and see what performance is observed. |

So, it may not be too far fetched to build a few designs and see what performance is observed. Both neon and fluorescent lights work in basically the same way; something is ionized with high voltage and low pressure and glows. Neon lights produce light directly from the gas. The color is determined by the gas. Common gases are neon, argon and krypton. Fluorescent lights have mercury vapor in them which glows in the ultraviolet. The inside of the tube is coated with a phosphor which glows in the visible region when excited by the UV. Black lights are fluorescent lights without the phosphor. In either case, the voltage is high and the current is low, meaning the resistance is high; hardly a good canidate for an antenna element. Not to mention the small problem that your antenna would contain a spark gap... -- Jim Pennino Remove -spam-sux to reply. |
