Roy Lewallen, W7EL Do fish have phasors? If so, then we know that they must keep rotating. Of course we can't figure out which direction they are rotating, but at least the spin continues. 73, Gene W4SZ |

And MK takes the bait, hook, line, and sinker. Actually, the hook, line, and sinker that was swallowed years ago is that a 360 cubic inch 75m Texas Bugcatcher coil can be magically shrunken down to a dimensionless point inductance that passes current with a zero delay and phase shift, i.e. faster than the speed of light. The technical truth will triumph in the end. A 75m Texas Bugcatcher coil occupies ~30 degrees of a 75m mobile antenna and it takes the forward current (and reflected current) ~21 nS to flow through the coil. -- 73, Cecil http://www.w5dxp.com |

You can only get so far with a general understanding but it has been said on this newsgroup by others that without a full understanding of the concepts you finish up with lots of misconceptions, and that seems to make makes sense when I read your postings. Are you an EE? Seems to me you were some type of mechanical engineer. If so, I don't see how your qualifications are a heck of a lot greater than mine. How would you describe your level of understanding? General? High? Massive? Einsteins lost step child? I could guess, but I'll reserve comment.. What misconceptions have I finished up with lately? Can you list them? I'd be glad to go back and review any I'm not aware of. . I suggest you keep quiet and wait until you can buy one then you are less likely to screw up. Why would I want to buy a gaussian antenna? I have no real use for one that I can think of. Besides, I don't generally waste money on antennas. It is not a design for a typical couch expert to expound upon. I've never been able to gather enough coherant details to expound on it, even if I wanted to. Also, I don't sit on a couch. There is one in the other room, but I'm never in there. I sit in a rollaround office chair, which hurts my ass in general. Needs more cushioning. A couch might be more comfortable, but would probably sit too low. I also doubt I have enough room in this clutterhut room to fit a couch... Suggest you wait until you can quote from a book if you want to impress I rarely quote from books. And I'm not here to impress people. Why would I try to do that when many here obviously know quite a bit more than I do? Or you for that matter... Would be like racing a pack of V8 corvettes with a V6 impala. I've never claimed to be any great guru of antennas. I just fart with this stuff to kill time, and maybe erect a bit better antenna than I would if I buried my head in the sand. I don't have any real "guru" ego to try to protect. I just call em as I see em.. I do have a few books, but I'm almost always too lazy to get up and find one to quote whatever it would be I would want to quote. But my comments still stand. I hear about all these new fangled gaussian designs, but I never hear much about you actually trying or using any of them. If I was trying to design a new type of antenna, I would test it in the real world before trying to convince the masses of the internet if it is a workable design or not. Seems to me it would save a lot of time. From what I read of your posts, I'm not even sure if you know if it's workable or not. To me, that strikes me as a weird way to live. MK |

Roy Lewallen, W7EL I like to stir it. But there is no fight to be fought. I'm not arguing with him. I just fail to see any real advantage of considering coil current "taper", or whatever you would want to call it when designing a typical bugcatcher. From many of his posts, you would think it's a required consideration, or rewards one with super performance not available to a designer using regular ole lumped coil theory. The coil is still going to end up being mounted in the same place either route you take. MK |
