For what it's worth, the latest prediction:

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. When this passage of particles to Earth spiked a few years back our grid became vunerable and the Northern lights were so bright they could be seen as far south as the equator. Now Cern wants to stop the Neutrino particles from the Sun by "impact" which suggests a coming presence of Hallium that can create explosive pressures such that artificial diamonds are readily made. When this experiment takes place it suggests that radiation will really peak for a short time before we all become incinerated. But the some scientists are comfortable that all that can happen is known. Well at least to the best of their knowledge and in the short term , we think, we hope! And we have not figured out radio radiation yet, even tho we have a multitude of formulae from a century ago! Fortunately the Sun has not burnt out and solar particles are still making it to Earth as the Sun's arbitrary border expands and fractures as well as the coming radiation fractures in Italy |

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. 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. tom K0TAR |

Speaking of texts, one of my co-workers gave me a wonderful paperback textbook last week "The Theory and Design of Circular Antenna Arrays" by James D. 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. I have no idea why he had this book or where he got it, but am grateful to get it. tom K0TAR |

Is this in line with your extensive design of antennas? |

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" |

Actually, unlike Wullenweber, they have multiple concentric rings of verticals in the array with a complex phasing system. My guess is that this may have been a contributor to the methods eventually used in phased array radars. But also something that was an engineering study, and not necessarily practical. tom K0TAR |

If the books say radiation is not "fully understood "(. Tom with one exception Tom OK?) I will take them at their word, well, at least until I publish the rest of the story..GDay By the way Tom, anybody can design an antenna as it is very hard for them not to radiate but to design an antenna that is more efficient than the present state of the art that is something else. 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. I know of no books that illustrate the use of the "weak" force with respect to radiation so would you say from your experience that Einstein was wrong? Even the books do not print that suggestion. Now one scientist has stated that radiation can be a point source which means the radiation sphere of a radiator is of equal value at all points around the arbitrary border, which of course is correct, and we are not talking averages either. Pray tell me how I should go about making such a radiator and what book is it to be found? Best regards and lighten up Art |
