It is oftimes said that parasitic elements of a yagi absorb
radiatiation and then reradiate half of what it received. Is this meaning that it only absorbs half of the radiation applied in its direction and where it then reradiates 100% of its radiation? It apears to be a simple question depending how one looks at it in terms of efficiency which could mean anything. Now in my unreleased Gaussian antenna array there is no interaction with respect to radiation as radiation cannot occur outside until the enclosed border is breached. On the face of it one then can assume that a yagi is not really efficient depending how one uses terms that have a special definition because of absorbed radiation. Thoughts! Auguments!. Trashing, or what ever trips your trigger. Just when you thought that Gaussian arrays would go away a thing like this comes along, go figure. ( Don't forget Pointings vector and what it implies.grin) Art |

Art ok, take each parasitic element on the yagi, break it in the middle to turn it into a 'dipole', add a voltage source set at 0v to drive it. now draw your imaginary boundary. i have satisfied your requirements, now why is my multi-dipole array not a gaussian array by your definition?? |

I see you have made over 116,000 posts just on usenet and that is just counting one server, all in the search of a fight and goodness knows how many aliases you have used every day. How about providing one of your many amateur calls? As far as your questions, you had every chance to discuss your problems with MIT but you ran for cover. Tom Donaly stayed and resolved his issue so why not direct your problem with the Gaussian law of STATICS with him., he appears knoweledgable enough, Whether he wants to fight with you is a different matter, you may have to go back to the Quilt making newsgroup to find your equal in statue.
