"This idea of waves moving along with the current flow and various other ideas put forward by book authors seems to be a never ending attempt to provide substance(d) to long ago thought out bad theory which would be disrupted if current was observed to flow in the center of a radiator." The theory is well tested and good. Authors often write books to inform. They are paid for their efforts. Skin effect is a fact of agreement among the scientific community. A proof is readily at hand. Coaxial cable keeps what`s inside in and what`s outside out. The best exposition of "skin effect" that I know of is found in chapter 27 of "Radio-Electronic Transmission Fundamentals" by B. Whitfield Griffith. The 1st edition was published in 1962. It was republished by Scitech in 2006. Art would enjoy and benefit from all 638 pages. Best regards, Richard Harrison, KB5WZI |

The funny part is trying to figure out who is the commedian and who is the straight man. Sometimes I think Art is just someone from the CB groups bashing y'all around. There is just too much consistency to his insanity. Jimmie |

Your measure of insanity is just different from mine Goodnight Art |

Still QRN is QRN. I just do not enjoy noise as well as i enjoy the desired signals. |

Best regards, Richard Harrison, KB5WZI * Richard I have made my thoughts known on radiation as well as the path I followed that brought me to where I am. In the past 100 years or more science has not come to a consensus as to what energy is. Einstein seached all his life for the weak force which he considered a major part of radiatiation which leads to a Unified theory. Today there is not one book thaat can provide a satisfactory answer as to how radiattion is created. What I am saying that there are to many theories that are being tagged upon one another leading to an incorrect trail upon which books are being printed for a individual generation. So I proposed to myself a retreat from the books and go back to Maxwells laws plus those of the masters that provided the information to him and then with an open mind looked at it with the 21st century in mind and the information garnered by observation as opposed to theory. Present day science is all a buzz about Neutrinos, CERN and the Sun which is in a continually burning state creating partly burnt constituents. Gauss has a law dealing with particles and I have an interest in ham radio. It is therefore natuaral to me that in light of present day observances Einstein may well have been correct even tho not aware of discoveries found after his death. Thus my concentration was on outside particles and not the wave style theorem and thus eventually arrived at the weak force phenomina which is in use in many ways on Earyth which can also be subcribed to radiation. But saying is not enough so I have used Maxwellian computor programs to design these antennas with good results all of which are bound to the edict of equilibrium which all the past masters adhered to. Einstein was not privy to a lot of things that I used on my jorney but many hams do and can easily confirm my findings which are observables not dreams that support Maxwell. Books cannot and do not provide an actual journey that provides a trail without gaps for the generation of radiation. I have by starting the trail at the beginning with present day science in mind and not pursuing the mode of academics who seek favor by piggy backing theories of those who have received award thus shutting out a;ll other aproaches. Yes my thinking is known and yes I think for myself with no formal attachment to the books upon which my education started where it is incumbent on graduates to continue to hone and secure futher information for the next generation rather than the sole pursuit of personal wealth.

"Einstein may well have been correct even tho not aware of discovries found after his death." Wouldn`t anyone like to be aware of all the discoveries made before his death? Einstein said something like: "Keep it simple, but not too simple!" Scientists have in many instances followed Einstein`s advice and reduced things to simplest terms. Maxwell`s equations as simplified and explained by Heaviside have been used to successfully predict EM behavior for a century. They give the answers needed so there has been no great search for a replacement. The research at CERN on colliding beams is more likely of interest to those working with ionizing radiation than to those working with the nonionizing type we use in radio telecommunications. There is and was agreement among many with Kraus when he wrote on page 37 of the 3rd edition of "Antennas": "Although a charge moving with uniform velocity along a straight conductor does not radiate, a charge moving back and forth in simple harmonic motion along the conductor is subject to acceleration (and deceleration) and radiates." An interesting view of the mechanism of radiation is given by B. Whitfield Griffith, Jr. on page 315 of "Radio-Electronic Transmission Fundamentals". Best regards, Richard Harrison, KB5WZI |

However, gravity serves a prime example of what you suggest, here. We know nothing about it, but a lot about its' affects and effects; we have many formulas to tell us about those and a few theories to tell us what it (gravity) actually is. So, I doubt it surprises anyone that we stand at, almost, this exact situation with EM. However, to lift the blanket and peer upon the true substance and nature of these things would take us to a whole 'nother level of possibilities in their uses ... So, if you argument is going to become, "We already know enough of these things, let us go no further"; well, some just may follow you--some not .... personally, I'd "druther" not ...
