Coherence (cross-correlating) is a statistical term for comparing (0.00 to 1.00) complex waves. You can have temporal coherence, spacial coherence, spectral coherence and on and on; none of which are actually named here, but whose various definitions have been notoriously cross-connected into a hodge-podge argument of no particular merit. Fortunately, we amateur radio operators are not concerned with anything that complex. We are concerned with essentially single frequency, phase-locked signals in a single-source, single transmission line, single-load configuration. Many levels and dimensions of complexity simply are negligible concerns within the amateur radio environment. Introducing irrelevant issues is just a diversion away from ideal examples which are relatively easy to understand.

I agree, you don't know the difference well enough to differentiate silt from mud from glacial flour - and yet you offer your fortified kool-ade. Your food coloring, sugar, and added special ingredients doesn't bring clarity (and as any nutritionist would say: sugar is empty calories). |

If Mr. Ohm introduced his law today, he would be belittled because it is not a theory of everything. -- 73, Cecil http://www.w5dxp.com |

wrote: Hi Arthur, Let's see if you can follow the inference of what you claimed to have sought in a reference for the signal strength of an antenna correlated to radiator length. It is a very, very simple example, two wires, no loads, very small: It takes Laport only 3 pages to name three references for the math (Stratton, Skilling, and Kraus); provide the equation; and directly state at the bottom of page 3: "directly proportional to the current and to the continuing on top of page 4: "length of the doublet..." No requirement for resonance, no mention of Q, the only resistance is that of free space, nothing about equilibrium, just a straight answer. The math has been confirmed by experiment, and it is duplicated in models that are fully consistent with all scientific enquiry for the past three centuries which exhibit every quality of the math and the quotation above. The text has been made FREELY available here. No need to purchase. There are no pages with pictures to color, so reading that far can be tough to master for one finding it difficult to search this out: I have searched quite a bit for evidence that states that performance of antennas can be rated by it's size. "Quite a bit" sets the standard for the whimpering of whipped dog denial. If just a teensy-weensy bit more effort were made, it is obvious the complete investment in antennas the size of a cracker-jacks box would collapse like the home-loan industry. The question carried with this is: if an amateur were given the choice between your design, and this simple two wires. then how much would he radiate or perceive any greater signal with your design? No doubt a very difficult question that will fail to obtain any metrics, and probably not even the grace of a direct answer. It is suitable for troll bait however, and the volume of response will weigh that accordingly. If providing the grist of measurement is so difficult to respond to, why are you here? Those who belittle do others a service by showing what they are. which may already answer my question with your burning bridges at every post. 73's Richard Clark, KB7QHC 73's Richard Clark, KB7QHC |

Ohm's Law doesn't work at all scales anyway - but Ohm would have been resilient enough to have taken it where it needs to go in this day and age. |
