Please don't confuse delay (amount of time) with the total phase shift. There is a point in a loading coil antenna where the phase shift is instantaneous. The total phase shift is *exactly* the same assuming both antennas are resonant on 40m. How could it possibly be otherwise? -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

If you had any idea of what you were talking about, you would know that the total phase shift is unrelated to the total delay. Some incremental phase shifts are related to the velocity factor. Some incremental phase shifts are instantaneous. If you don't already know that, you don't know how to use a Smith Chart. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

But you're doing all the talking, Cecil - providing profound and knowledgeable insights as in the above observation that phase shift and delay are unrelated. ac6xg |

Is there a third, unpublished, cosine parameter (Suppressed Hypothetical Interval Term) for delay that is not phase nor position? This must be another one of Cecil's "you are right, but you are wrong about what you thought you were thinking about." 73's Richard Clark, KB7QHC |

I suspect it was because Cecil was wrong about what he thought I was thinking about. Again. Either that, or he was referring to standing waves of current that 'begin undulating linearly & laterally' at a 'cosinusoidal reduced amplitude phase'. 73, ac6xg |
