This has lead us to the obsurd present point where a cubic foot size
antenna for top band should have its reflecter a couple of blocks away and of a size stretching for several thousand feet instead of a few inches where if the antenna was a ball of presureized water the close reflector would prevent the jet of water spreading to the rear. Given a 3 ft copper dipole on 1.9 MHz the free space gain is -4.6 dbi, and exhibits a classic dipole radiation pattern. Placing a 6 ft diameter, radial reflector 3 ft from the antenna has no effect on the radiation pattern, other than a slight reduction in gain to -5.2 dbi. Frank |

Frank you really don't think art is going to believe that do you?? it is after all based on a piece of software using maxwell's equations... which he has said he believes in and that the software works, because it obviously shows that his antenna produces a spotlight beam when you tilt it the right angle... but he won't believe yours. |

Ofcourse I do! it is very logical You certainly must have a reflector that extends beyond the emmiter dimensions A dipole extends about 500 feet where as mine extends one foot.!........Big difference. Like comparing a miniature light bulb with a string of flourescent lights in an office building. Has it quit raining yet? you seem to be all wet I think you need to speak to the Navy and provide some of your expertise. One Navy port has tilted all of their antennas for better performance per the permission of an Admiral no less. Do you know more about antennas than they do? This analysis is easily proved per Maxwell equations so you should be able to dispute what the Navy did. Why are they tilted? Because they are including the "weak" force present in Maxwells calculations. Is Maxwell all wet too? Computer programs based on Maxwells laws prove it is correct so try Eznec for your self. Tilt a long wire from vertical until it is fully resistive and the field will show gain. You just do not have any clothes. |

Oh my! It is in Maxwells laws, without the weak force you cannot have equilibrium. You are getting a bit silly now. There was a guy in this group who stated that the weak force was ficticious. He must be a submariner to. All computer programs based around Maxwells laws have it to if one wants to account for all radiation but most just want to design a Yagi because it is easy to build.

Art You would make a good politician: When you don't know the answer, change the question. He challenged you as follows: "please state the equation and term that describes the weak force." You answered: " without the weak force you cannot have equilibrium." I too am waiting for the answer to his question. Which of Maxwell's equation(s) contains the weak force and show us specifically which *term* defines the force. We already know that you took the position that weak force is included in one or more of the Maxwell equations. |

We already know that you took the position that weak force is included in one or more of the Maxwell equations. you'll never get the answer. his only response last night was for me to try to duplicate one of his rediculous optimizations to get a tilted dipole. he doesn't know even the most basic math behind the equations, he has latched onto the gauss equation drawing (not the equation, just the drawing mind you) that shows the surface integration around a charged object and is doing everythign from that... the rest of it is made up from misreading, or just plain not understanding, other news articles that have some kind of percieved relation to em fields... for instance his latest fasination with the weak force is from the use of the term 'electro-weak' force, while this is well known to be confined to the nucleons in an atom he has extended it to his fantasy world to explain the tipping of dipoles over ground to get gain... my recommendation is to keep prodding him for fun, but ignore anything he says. |

..... There was a guy in this group who

All computer programs based around Maxwells laws have it to if one wants to account for all radiation but most just want to design a Yagi because it is easy to build. Art In fact no one has said that the "Weak force" is fictitious. The comment was in relation to the usage of the term "Electro-weak force". Frank |

Frank Frank Electro weak is what some continue to say for the weak force. Assumption being that it is electrical nature and part and parcel of another force. When David does his thing with AO for himself he will inform you of the angle of the weak force and may even provide its magnitude. His series of questions and statements stop here. If I supply answers and he rejects implementation then we cannot move on. He is just baiting or he wwould tell you what AO provided. All have a chane to resolve the question for themselves thus relieving me of challenges as to my integrity. I cannot satisfy anybody and they cannot satisfy themselves We now enter the stone throwing stage and the thread comes to an end Have a good day Art Unwin KB9MZ.......xg |
