The impedance of this path is lower than the impedance to space so naturally that is the path the power will take. Now on this inner path there are no electrons to dislodge as the outer electrons have decayed before they reached the center path so the current during this time is just travelling without supplying radiation until it reaches the bottom of the radiator. But it's counter part the quad is radiating during this time ( How about that experts!) And by the way it was mentioned somewhere that the ground resistance was 2 ohms so one should now be able to determine the IMPEDANCE of ground at the antenna base point Now you take it from there....experts!

Art KB9MZ...XG ah, the no electron anti-skin effect return path up the middle of the element. what about my elements that are hollow? where does the current flow then? or where does it flow in wire cage elements?? what about coiled elements like that 'new' short monopole, does it flow around and around inside the wire, or take a shortcut through something else? How does this fit into current wave reflection theory that easily explains the currents on elements complete with easily measured and well predicted values that don't require a return current up the middle?? too many questions left hanging art, you gotta work on that theory a bit more to fill in all the holes. oh, maybe thats it, try incorperating holes into your next version, maybe thats how the current flows back along the inside, it is the holes left over when the electrons 'decay'! |

Won't you be embarrassed when he sites you as his authority for your cogent analaysis! 73's Richard Clark, KB7QHC |

It is now in a quandry it looks over at the quaud and ssees that the charge over there is half way around! So the charge on the small radiator finds that it can only go up aqgain forming a loop of current. Fortunately it is now back on track radiating just like the quad. Ofcourse when he gets to the top it again has only one place to go and that is down the center again where it can't radiatiate like the quad is doing.When the charge gets to the bottom it wsees a path of 2 0hms (the resistor) so it passes thru the resistor where the charge finally gets back to the starting point at exactly the same time that the charge of the quad got back home. So the sequence of events is that the short antenna only radiated half of the time neglecting the travel thru the resister of course. So the quad radiated twice the time of the smaller radiator which amounts to a 3 db gain. Well some might say we knew that a quad radiated more because it is the same as two dipoles( half wave) on top of each other so yes for the same power expended in the same amount of time a full wave radiator radiates twice the power that a quarter wave does. Art you are a genius put QED at the end of this post and also get hold of Yuru so that he now can get to sleep at night. Art Unwin KB9MZ.......XG (uk) |

Well, society needs Libras who can believe six impossible things before breakfast. Imagine, we get to see them posted here before brunch too! |

RF i am convinced that art is playing dumb on purpose.... no one with any knowledge of antennas and em fields could possible get this screwed up on basic concepts. when he was just talking 'gaussian' and 'equilibrium' stuff it could easily be laughed off as someone with a little bit of knowledge trying to force the rest of the world into that single concept. but now with decaying electrons and current down the center of the conductor and a missing half cycle its just too far gone. i had been kind of tagging along tweaking him into trying to explain the details of his concept, but now it is apparent that he has none. he is just making it up and stringing us along. you gone too far this time art, ciao and enjoy your game alone. |

Awe common Dave don't go away this is fun! Now what is wrong with current going down the center because the impedance is less than 377 ohms? Remember if you go up in altitude the 377 impedance will go down and become less that the wires internal impedance the energy will transfer to space with that smell of ozone. That is what happened in Quito Equador That is what led to the design of the quad where a lesser impedance path was provided for current flow! Now the inner impedance of the wire must be pretty high to create an end effect so with Isq R there has to be a lot of heat generated. Remember Vincent saying his first antenna melted? Now we come to rotation of a projectile. Did you know that a projectile tumbles and comes under the influence of the Corrioli effect as it losses energy.A shell starts to tumble when it exceeds it's range Next time a rocket goes into space watch for rotation. What do you think causes that? A train speeds along on a railroad until at a certain speed it will roll over, why do you think that happens? Look up "hammer blow" for that one. How can I possibly be stringing you along? You can put everything to bed by spending a 1/2 hour making a full wave antenna but ofcourse that means an effort to get off the couch ! Yup It is better to stay rested and let your mouth do all the work at least until you start to dribble. Art Unwin KB9MZ....XG |
