There is no .EZ, .GAA, .N4W or .NEC file for me to play with and tear apart. I can't even tell what the antenna looks like from what you've posted. You have two elements each located with x,y and z *co ordinates at each end, so you make your own file to suit the program you intend to use or is available. I do not have two elements. *I can't located them in x, y, or z because you didn't specify any such coordinates. *I can make a suitable NEC deck, but *YOU* need to supply the numbers. Surely you can model anything if you know the end locations of the elements. I certainly can. *Now, can you supply those end locations? *While your at it, the height above ground, element diameter, material composition, etc might be good to disclose. * Also, why make me do all the work? *You have obviously created a data file for some unspecified NEC2 modeling program. *Why not just post the model? If you are unable to do that then may be it is better that you don't. Try not. Do... or do not. There is no try. * * * * * * * * * * * * * * * Yoda There are to many programs around for me to make files for every body and every program that is available so I supplied x,y,z co ordinates which every body can translate. Yep. *Pick one. These are the points you should look for to determine what the antenna looks like. These are what points? *You haven't supplied any numbers. Either way I have supplied the results to save you the work. Generous of you. *If you don't disclose any numbers, it's not a model. It's a bad joke. *Try harder. -- Jeff Liebermann * * 150 Felker St #D * *http://www.LearnByDestroying.com Santa Cruz CA 95060http://802.11junk.com Skype: JeffLiebermann * * AE6KS * *831-336-2558 Just let it drop! I use Minninec not NEC programs I really do not want to fight with you or anybody on this even tho many want to. I made the post as a point of interest and to share only. To show what polarities it was sensitive to even tho many want to fight regardless of what I post. The majority on this newsgroup are not able or interested in modeling which is why I posted the results, otherwise the intent would be lost on them. Ever since I declared that a static field in equilibrium, when made dynamic, is applicable to Maxwells equation for radiation it seems like everybody wants a piece of me even tho they are completely ignorant of the physics involved. The model provided is complete evidence of this fact which as yet nobody has been able to refute prefering to personaly harm the messenger. Maxwell gained fame just by adding /dt to an equation which made it dynamic, and apparently many on this newsgroup want to deny him of his achievement because the importance is not illustrated in any physic books. Frankly, if you can't live with history you should be challenging computer programing that utelise 1/2 wavelength radiators where the energy lost by the components is ignored as is the EXACT length of a 1/2 wavelength which varies with every cycle! Use of Maxwells equations are for radiator designs that are sensitive to ALL polarities directed at it for maximum efficiency, and not for those designs that it ignores or cannot handle. Art KB9MZ |
