Lumped loads are not included in the laws of Maxwell only distributed loads Art |

Yes, it has distributed loading but formed into a helix antenna such that it includes lumped loading. Maxwell in his search for maximum efficiency he would have added a symbol to his equations for lumped loads . He then would have to include pitch and the like but he just did not consider it as a consideration. This is clearly shown with a WL verticle when for maximum effeiciency it is tipped from right angles to the Earth ala the Corriolis effect with which you are tampering with when current rotates, and its introduction of a slow wave and a different velocity factor This is why you cannot equate lumped loads with antenna degrees, only approximate I have no which to debate it so I will leave it at that. Soon I will be heading home. No offense intended but physics is physics Art |

Maxwell in his search for maximum efficiency he would have added a symbol to his equations for lumped loads . lumped loads like capacitors and inductors are indeed included in maxwell's equations, its just a matter of scale. the problem is that most modeling programs can't handle the large scale variation needed to go from a large radiator down to a small coil and still maintain the segments properly. but indeed the fields from and within the lumped elements do follow maxwell's equations. This is clearly shown with a WL verticle when for maximum effeiciency it is tipped from right angles to the Earth ala the Corriolis effect art is a bit tipped from vertical also, but i doubt if it is a corriolis problem. |

I don't quite understand this. Could you elaborate please? Roy Lewallen, W7EL |

No offense intended but physics is physics Art Hi Art, Can you reference a professional journal that confirms this Coriolis (I believe that is the correct spelling) effect w/ respect to tipped verticals - or is this something only you have discovered?

Yes you are correct David. Coriolis effect is well known where as the weak force is not because of resistance to change. The Coriolis effect can be observed by looking in the toilet bowl in the different parts of our Earth. Whether the change over effect observations alignes with the equator I do not know as I am now home in Illinois and have no wish to travel more today .. As for reference in professional papers take note of equations for displacement current as stated by Maxwell which I refer to as "the weak force" that Einstein spent so much time in looking for without success. This force is one of the four forces alluded to in The Standard Model of physics |

Maybe this gets to Faraday Rotation? The Coriolis Effect is on particles, not waves, right? EM waves have no mass. |
