Meaning you don't want anyone to disagree with you. What I invite is someone disagreeing with me about a 75m Texas Bugcatcher coil along with some technical proof that I am wrong. All I have gotten so far is ad hominem attacks. Where's the beef? Dr. Corum's empirically-based equations do not work for toroidal inductors so they are outside the scope of my discussion. Why not discuss the most common large air-core coils used for loading 75m mobile antennas? No he wouldn't. You don't know what he would have measured. I have exactly the same coil that Tom used for his "measurements". I have measured the traveling wave delay through the coil by loading it with a 5k resistor to eliminate reflections. I do know what he would measure if he would only run the experiment correctly. You could do it too if you so chose. x and y are the current sample points. source---x-Tom's coil-y--5k load +-------------------------+ Maxwell's equations don't say anything about "slow-wave structures." If you are saying that Maxwell's equations are invalid for slow-wave structures, your argument is with Ramo, Whinnery, and Dr. Corum, not with me. http://www.w8ji.com/agreeing_measurements.htm "As described in my posting on rraa of November 11, the inductor 'replaces' about 33 electrical degrees of the antenna." Are you sure that isn't a quote from Reg Edwards, whose ideas you stole in the first place? You are free to access the above web page to see who wrote it. If Dr. Corum stole Reg's ideas, he should have given him the credit. Dr. Corum does provide 50 references for his paper but Reg is not one of them. However, here is a partial list: 7. J. D. Kraus, "Antennas" 19. F. E. Terman, "Resonant Lines in Radio Circuits" 23. J. D. Ryder, "Networks, Lines, and Fields" 29. S. Ramo and J. R. Whinnery, "Fields and Waves in Modern Radio" 30. R. W. P. King, "Electromagnetic Engineering" 43. M. Born and E. Wolf, "Principles of Optics" -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |
