I was reading up on the above antenna which is a take off of an antenna I patented ,( Constant Impedance Matching System) and written up in QST March, 1998 I also described this system in earlier postings on this newsgroup.------------- --------- antenna) ART What page? Can't seem to find the reference in March '98 QST. -- Frank Thought about past times so I looked up comments on the OWA antenna on the net and got the reference to QST from there. By the way this newsgroup laughed at this and ridiculed me when I explained it a few years before the article was written, the same way they ridiculed with the Gaussian antenna. A lot of people were pointed to this patent by the patent office with respect to their claims. Note Cebik did some follow up writing on that antenna.I applied for another patent along the same lines at the same time but let it go when my health went down hill! Art Googled OWA and checked out he design of the antenna, Isnt this is pretty much what you get when you let a program likeYagi Optimiser tweak the antenna for max bandwidth vs SWR? Seems like back in the 70s I remember some truck stop special CB antennas built like this that made great claims for their SWR. No doubt the claim is correct but what is the tradeoff in gain, cost, ruggedness..... Jimmie Jimmie- Hide quoted text - - Show quoted text - Jimmie, If the cb antenna is the same as what I disclosed in my patent I should not have obtained the patent! I do know that a few patent requests were referred to my patent after I disclosed it on this newsgroup so it seems odd that I and others were not referred to the CB antenna as being the prior art. As far as gain trade off there is none. The constant impedance allows for continuation of gain at band edges when the gain striven for is to high for the bandwidth in question. But then this is just a patent, and I have always found that people would always say I already knew that or it has already been invented. Odd how some people react to the new or change. It will be the same for the Gaussian antenna as already one has stated it has already been invented but does not give particulars. On the impedance antenna I had numourous requests to go to San Francisco with all expences paid just to discus the basics and future but health problems of the heart told me to forget about the whole thing as well as the sarcastic comments from the resident experts of this group which continues to this day. I don't need money so I am glad the idea is still alive ala Cebik who has written extensively about it. Really you should refer your questions to him rather than entrap me into another augument. Art Wasnt talking about your patent, I found about OWA has no similarity to your patented design, They were just normal run of the mill yagis optimized to have a realtively flat SWR over there design range. Nothing new. Jimmie- Hide quoted text - - Show quoted text - Pound to a penny that you never read the patent or comments given on this newsgroup in the mid 90s or even OWA descriptions You can always give me a pointer as to why it was "run of the mill" matching system or where the OWA was different, or all the same. Like all things new comments abound that "I already knew that" or "it is nothing special". What is it that you have against progress with respect to antennas? Seems like any opposition to " all is known about antennas" is a signal for attack Art in ham radio these days to keep the status quo! Art You lose, give me the pound..- Hide quoted text - - Show quoted text - Your past shows that you are not the type to look up archives but demand it of others to do it for you. bSorry but your answer has no credability. Run of the mill indeed Whenever I reference an archive I always leave a path to it. Can you say the same. |
