Real time proof of Poyntings vector
"Richard Harrison" wrote in message ... Jimmie D wrote: "My first encounter with Gaussian antenna was with microwave relay paths and "flyswatter" antennas." We called them periscope systems. Nice because instead of a waveguide loss, the periscope gave a gain over the dish alone. The reflector at the tower top has a cupping adjustment to refocus the energy thus boosting the gain. When satellite systems appeared, the FCC started to lean on private microwave users to replace existing periscopes with "high-performance" dishes at tower tops. Long after we complied, I noticed FAA relay systems still using periscopes. Part of the problem with periscopes, I believe, is the common practice to use tower top reflectoers that are too small, for economy and performance. You believe correctly, especially the ones the FAA used. Part of the would-be illumination is allowed to fall outside the surface of the reflector. This boosts gain of the periscope as the outside ring of the illumination is out-of-phase with that in the center. I don`t know about Gaussian dishes, but maybe they concentrate in-phase energy in a narrow beam and eliminate the out-of-phase energy. Best regards, Richard Harrison, KB5WZI |

Also one states that the computor programs prove there is nothing new. Another states that there must be coupling of some sort what ever he was trying to say. Another questions what is new when all elements in the array are resonant. Another says that it is really a messed up Yagi. Another advocates that elements should be put in line.

What is it that the amateur radio community really want and is the knoweledge base shown on this newsgroup a reflection of the amateur radio co0mmunity as a whole. I invite anybody to respond to this poster to give him some satisfaction as to what the ham community is wanting to know. Please provide a sample response on how one should reply to the many statements and questions provided. Should I go thru the whole scenario of describing the underlying basics of this antenna when I know some cannot or want to read postings other than their own. Lots of the experts state they do not understand this or that but do know enough that the whole thing is rediculous. Is ham radio just all about old men, morse code and protection of the past? I do suspect that the silent majority is getting larger by the day as the grim reaper becomes closer and closer? Art Art |

Gravity, theory and equilibrium is way to much to foist on amateur radio operators. Most are so old and have little time to sleep or live that they wouldn't be around at the end even if we could get there because of constant opposition to the use of the words. I thimk Frank, a start on another attenna aproach such as the concentration of time and computor work by Cebik and Antennex in efforts to get an antenna that can be matched over a wide band. I don't think they got anywhere but maybe a review would be in order of making the driven element really thick which they say is the way to go. Maybe making the driven element thicker than the length of the element is the way to go to prove this concept that they are trying to prove. Perhaps the old timers can give us hints about a similar aproach that they invented years ago that nobody took notice of. After all every thing is really known except how to put a PL259 connector on a coax that hasbeen ill treated by being stepped on. I will have to rethink all this after I have found out what Paris Hilton would say. |

Jimmie- Hide quoted text - - Show quoted text - How about, Gravity being the center of a mass whose forces pushing outwards repels forces pointing inwards until the mass evolves into a state of equilibrium. Where the same forces come into play with all items of mass or energy where these forces equalise and retains balance with all other objects within the Galaxy. Since the Galaxy is expanding it's make up parts are consistently changing because of the changes in attractive and repelling moments as they seek to readjust to fill the surrounding entity which is limitless. If the energy of an entity decays such that inward forces cannot be repelled the expansion of the universe mechanism becomes interupted by the formation of black holes and where moments become redistibruted. Thus gravity can be defined as the mass or energy which is determined by the opposing forces to the particular entity to obtain equilibrium. O.k. guys wrap your mind around that sucker starting at the equivalent point of mass and energy and its interchangeability. Cecil you get first shot at pushing the barrel downhill and the others get the next chance to stop it. Art |

This is also analagous to electrostatic and magnetic forces where F can be attractive or repelent. I wouldnt write of the posibility that this may be also true for gravity just yet. Jimmie |
