No need to worry about the tower falling down due to additional mass from energized electrons. :-) The antenna is charged up to a certain energy level during the key-down transient state. Since the energy content of the antenna cannot increase forever, it must lose energy as photonic radiation and/or as heat during steady-state. Free electrons in a conductor travel at much less than the speed of light. Photons are emitted from the electrons at the speed of light. A quote from: http://c2.com/cgi/wiki?SpeedOfElectrons "For example, for a copper wire of radius 1 mm carrying a steady current of 10 Amps, the drift velocity is only about 0.024 cm/sec!" i.e. about 0.01 inch/second. Ignoring random movements, the electrons at our RF transmitter never reach the antenna. At 10 MHz, the electrons move less than 0.000000001 inch during a 100 nS cycle involving a 100 watt transmitter, i.e. they mostly oscillate in place. That are speculations only. Everybody know that at the end of an antenna the high voltage appears. It means that density of electrons change. The movements must be bigger. However, other electrons, traveling at a large percentage of the speed of light, are quite massive as observed in particle accelerators and radioactive decay. They escape from metal with the high velocity. Nobody know how velocity is inside metal. S* There is no "velocity " inside a radiator. There is a current flow on the surface and when there is no skin effect at the ends of a radiator that is not in equilibrium then the charge is free to flow off the ends but without contra or levitating spin just like a helicopter when one of its rotors comes to a stop. The rotor that is still turning takes a spin increase like a motor start up with no load until a spark is realised when the spin rotates at a particular frequency |

Actually, the fact that they try to bunch up at the ends of a standing wave antenna during part of the cycle implies that they slow to a stop thus repelling other electrons and have nowhere else to go except to reverse direction during the next 1/2 cycle. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

Obama should have his new grid in place before the next sun cycle so the lack of large sun spots are doing Mother Earth a favor. Regards Art |

"Szczepan Bialek" wrote in message ... both. when the current is high in the center it is creating a stronger magnetic field, and when that current reaches the end it creates the highest voltage so makes more electric field... both are part of the electro-magnetic wave. It is not Maxwell model. In it current create magnetic field and THIS field create the electric field. AND SO ON. ah, you believe 'and so on'?? the 'so on' means the changing electric field creates a magnetic field... both conditions are required for electromagnetic propagation. without the time varying displacement current there would be no propagation. so yes, you can create a magnetic field from the time varying electric field. Your (engineering people) model is O.K. but it is quite different from the Maxwell model. This is the reason that Art can 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." the maxwell equations completely describe radiation from an antenna, so all antennas, even arts, 'conform' to the maxwell equations. |

David I am not ignoring you. I have responded to lots and lots of your questions but you do not respond in kind. It started years ago with a time varying current being applied to Gass's law of Statics and you have rebelled to everything said since then, and not once have you explained the definitive reasons as to why you reject all. As I have said many times, I do not work for you. I am not in your employ. As for Maxwell's equations, he accounted for all the forces involved in the generation of radiation within the boundary of equilibrium. A Yagi is not in equilibrium so the difference is chalk and cheese. Both radiate ofcourse tho the sizes do differ as does the bandwidth as well as the TOA but the point I am making is that if your radiation assembly is not in equilibrium you are not following the tenents of Maxwell. A very simple distinction as is the accelleration of the charge contained by a departing particle compared to a wave of some sort or energy content that is capable of a straight line projection without interference from gravitational forces or progressions to the existance of light, X rays, e.t.c. Have a very happy day and sleep tight and don't get your knickers in a twist Regards Art |

If you supply energy to this mass in equilibrium the frequency of rotation of particles increases and could increase to the point of the frequency of light where, if it continues, could become vaporised such that we now have a new medium consisting of partial pressures of gasses. Just amazing in it's wrongness, but it could easily convince the ignorant masses our schools now create. This is just incredible fiction! How do you do it? snip Art tom K0TAR |
