Perhaps eh/cfa testing results are clogging the queue. Of what use is it? Bragging rights of the ****-ant stature. Into what are the numbers inserted? second only to preparation H for that application. What is the next stage in the proposed modelling process? creating a new icon to worship. C'Mon, Reg, you new those answers all along! |

As I said on the other newsgroup, Reg, it is useful for discrediting the assertion of one of r.r.a.a's ex-gurus.

-- 73, Cecil http://www.qsl.net/w5dxp ============================== There's no such thing as a perfect coil. All coils have stray capacitance and resistance. Consequently, it's exeedingly unlikely the current at one end is equal to the current flowing at the other end. The current flows out of the coil via the stray capacitance to its enironment. So we don't just have I1+I2 - we have I1+I2+I3 to contend with, where I3 is distributed along the length of the coil. Not that anybody in his right mind would ever wish to know the magnitude of the taper of the current or volts. Seems to be an invention of the denizens of this newsgroup, most of whom seem to have lost theirs. Now, Cecil, you understand this as well as I do. Cease pulling my leg. So don't expect me to waste any more of my time discussing it. ;o) ---- Reg, G4FGQ |

Because Yuri didn't agree with that assertion, he was accused of being lower than the deepest layer of whale sh*t in the deepest part of the ocean. Can you blame him for reacting? -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

A long thin coil [like a Hamstick] requires a longer length of wire than a short 'fat' [note the quotes] coil [like a bug catcher or a screwdriver]. The hamstick has a higher current taper than the screwdriver or bugcatcher. The resultant integral of the current and length [in degrees] [ampere*degrees] of the resulting antenna is higher with the short fat coil than with a long thin coil. {This assumes the coils are located approximately at the same location.} Deacon Dave, W1MCE |

I think the dispute is over the theoretical and the philosophical. And of the pictures describing the phenomenon. 73, Jim AC6XG |

What is the next stage in the proposed modelling process? You got me. Note that Wes mentioned on his web page that the lumped coils he modeled, seemed to more resemble "real world" results than the distributed coils he tried. MK |
