LOL...A dummy load does great in the SWR dept.. Doesn't mean
I want to use one as a radiator of my precious RF... :/ As far as Art's matching design proposal, I can't see the '98 article in question, so as usual, my cat has mittens. MK All I can find on the web is the following. http://www.cebik.com/qex/owa.pdf http://www.antennex.com/shack/Nov00/dan_edit.htm http://www.cebik.com/vhf/owa.html Some mention is made of QST here, but they did not seem to actually publish the article: http://www.naic.edu/~angel/kp4ao/ham/owa.html By the same author '98 QST, pp 38 - 40. -- Frank |

Also Cebik is selling computor disks on the subject. Shame Jimmie and others didn't attend Dayton to point out to the amateur world the shortcommings of such blather and nonsense with respect to antennas. If they did that they could have placed themselves in a position to be high lighted in next months QST. I am sure all at Dayton would have been all ears to their antenna expertese with respect to various antennas. You also could have asked them why their patent request was rejected ! If you look back at the archives around 1995 Jimmie may find it interesting. By the way Frank a short time ago I was blasted for something inmy past based on more than a single reflector. I find it interesting the FM antenna on the net that described the reason for three reflecters by the author of AO *( Brian Beasely) so you can easily determine who knows what he is talking about on this group despite the impressions they try to create.

Regards Art- Hide quoted text - - Show quoted text - Frank, I have been al over the place on the net with respect to articles on OWA antennas and the only claims made are only per ideas. Ideas can come from any where which also can include variations of known patents so I see no problem./ The important point that was missed that the closeness of the two elements is certainly not intended as to provide a thick element to provide a wider band impedance around which Cebik has written many articles. True my method can provide wide gaps between the elements as well as very narrow spacings which is where I focussed. Basically my feeding method was the opposite arrangement where the feed side of the matching system and where the element was split to form a radiating loop nprior to the transfer point .. The transfer point from this loop depended on the frequency of use just the same as one would do when finding the ideal impedance connecting point for any radiator. However, every thing I have read is inferring that the band spread of the OWA is created by two elements acting as oneto provide a thicker element which ofcourse affects band width, but not to the extent that it truly worth while. Unfortunately Cebik bought this line of thinking and extrapolated everything he wrote from that stand point which is a pity. If the seed had not been planted in the first place he would have found things that have escaped him this time around and hopefully one day he will realise the wrong turn that he made and share his ideas in a more fruitfull way. This ofcourse does not prevent others from picking up the ball and getting personal benefit from it as I let the patent die when my heart faultering problems suggested the patent may not be the first thing to die! At this point I would add that the Gaussian aproach is a much better one by placing all data curves constant and in sync with each other which has been major in creating a narrow band array as well as providing constant gain like a band pass filter curve and not a curve where different best f/ r and gain peak frequencies forces compromises. Either way my reading enforces my opinion of Cebik who is performing a valuable service to ham radio since he writes things as he sees them as opposed to slanting to what he would like to believe, a very valuable attribute.
