"Szczepan Bialek" wrote: The first sensible question. "Radials and Counterpoises have two basic purposes: 1. To improve the RF ground conductivity for the ground current return path. Unless you live in a salt-water swamp, your ground conductivity makes a very poor path for the return of ground currents. This increases the ground losses and reduces the efficiency of an antenna that needs a good RF ground. E. More radial wires are generally better. As the number gets larger, they improve the RF Ground less and less, to the point where there is no difference when adding one more radial to a system that already has 120 installed. Minimum systems of as few as 4 wires can provide an acceptable ground and increase the antenna's efficiency by a significant amount. Generally, 6-8 radials is the minimum that should be used." From: http://www.sgcworld.com/radialstechnote.html If you believe ANYTHING that was published by SGC, you need to go back to school and relearn everything you ever thought you knew about RF Antenna Systems. There is a reason Don Stoner, left the company decades ago, and PeeAir couldn't design his way out of a Wet Paper Bag. As you see in the radials are many ends. There is the lower voltage and almost no radiation (electron loss). Radial work like the receiver antena (caught electrons from air) Without the radials your stations can work only in a "salt-water swamp". S* |

We are discussing on the pulsatile flows of electrons and emission of them from antenna end at transmitting. At receiving the pulsative flow is in the oppsite direction. Do you agree? S* |

It will be lower in 10 radials than in 6. oh, so it does double at the end of a radial.. that is different from what you said earlier. Existence of the standing waves was shown by Oliver Lodge. They are in each wire. as opposed to the electron at the end of an antenna that does double?? You know what to do to have low VSWR. Low VSWR means that the voltage is so high that the intensive emission of electrons take place. At higher voltage the emission or sparks make low VSWR. oh, so the swr changes with transmitter power? I wrote: "You know what to do to have low VSWR". Do you? that is an observable prediction that is obviously false... go back to square 1 and start your theory over again. Here no new theory. Pulsative flow and the field emission are very old. Is the pulsative flow of electrons in antennas? S* |

S* no, the flow of electrons stays in the antenna and is sinusoidal... they do not jump off the antenna. |

In a cristal radio is the diode. The electrons flow from the antenna to ground. Where they come from? they do not jump off the antenna. They must do it in the transmitting antenna. They are members of "pulsatile- composed of a mean flow superposed with an oscillating component". In reality no "sinusoidal...". The forward motion is always stronger than the back. S* |

S* give me a number. if i transmit 1kw on 14mhz how much dc current must my transmitter be supplying in addition to the 1kw ac sinusoid that my meter measures?? |

"... for a copper wire of radius 1 mm carrying a steady current of 10 amps, the (electron) drift velocity is only about 0.024 cm/sec". At 100 ns per RF cycle, the above electron moves back and forth about 10 nanometers, i.e. it doesn't "flow" anywhere except at DC. At RF those electrons never make it from the antenna to ground and instead essentially vibrate in place. The only thing that flows at the speed of light is photons/fields/waves. The slow-moving vibrating electron carriers form a bucket brigade for the fast moving photonic energy. That fact of physics wasn't fully understood until the field of quantum physics matured. EM fields and waves turned out to be particles that are photonic in nature. -- 73, Cecil, w5dxp.com |
