Tillman, Jr., The University of Tennessee Engineering Experiment Station, 1966. The design, testing, scope pictures and the wonderful racks of gear they built makes for a great piece of work. Just a guess, but maybe it deals with the Wullenweber [or Wullenwever] antenna, described here http://en.wikipedia.org/wiki/Wullenweber and elsewhere. The article cites Hanza, Okinawa, Japan, where I was stationed in 1965/66 and worked inside the antenna building. The basement was filled with multicouplers and several very large spinning goniometers to pick off the desired signals. It also cites the array at Imperial Beach, which is not far. I see it several times a year but it was abandoned years ago and may be coming down. I wonder who gets all that nice RF cable. "Off-topic Sal" |

Art, please do not include the majority of us here in your statements. What you really should be saying is YOU have not figured out EM radiation yet. I for one can design and build, with the help of STANDARD TEXTS (especially those many decades old!), almost any type of antenna or antenna array anyone could ever need. And it will work exactly as predicted if one takes into account normal environmental variables, such as buildings, trees and ground conductivity. Everybody should see that engineering people know his job. This isn't unknown unpredictable territory, regardless of your claims, none of which have been proven, by the way. This stuff works, and we know how, and it's not the way you claim. You all know how. You have yours own STANDARD TEXTS. But I do not know the one thing. Which part of the antenna radiate. See; (http://people.seas.harvard.edu/~jone...Hertz_exp.html "According to theory, if electromagnetic waves were spreading from the oscillator sparks" The theory is from XIX century. The oscillating sparks are in the centre of the Hertz dipole. What do you assume in your predictions. Are the radio waves radiated from the end (no current) of an antena or from the places of the wire where the current is max? S* |

S* both, and neither, art's radiation comes from magical levitating antidiamagnetic neutrinos from the sun that jump off of antennas when the current flows. |

Gauss's law of Statics is the subject law. Waves have no part in that picture can'tyou get that into your head. The Moon creats waves The Sun does not Again "statics" which is the subject of particles is what I was talking about. |

The Cern experiment scheduled to start this year seems to me to be an attempt to stop particles in their tracks faster that the Earth's atmosphere can. It sure doesn't take you long to hijack and deflect a thread into a Troll-A-Rama. |

I always thought Art had confused statics with statistics. |

S* both, and neither, art's radiation comes from magical levitating antidiamagnetic neutrinos from the sun that jump off of antennas when the current flows. Earlier Art wrote: "For your information you have never built an antenna that conforms in its entirety to Maxwell';s laws thus you cannot possibly understand radiation as presented by Maxwell. For instance, Einstein studied Maxwell's laws in the hope of finding the properties of the "weak" force. He failed. He then decided to move away from standard physics to look at things from another view point but still failed." So Art is looking for the next theory. It is a good way to know the results of experiments. Maxwell did not see the antenas. You all do. Tell than us which part radiate the radio waves. S* |
