Why does one photon wind up in an inner interference ring and one wind up in an outer interference ring? Nobody knows. Methinks you have left the world of deterministic Physics and moved into Quantum Physics. Such comments do not contribute to the answer. You are not using Quantum mechanics to try to explain to me what is happening. You are using transmission line models. Stick to the transmission line model. I thought antenna EM Physics was deterministic. - - - - your model. You stated: "Anything done below the coil affects the number of degrees subtracted from the antenna by the bottom element to coil interface. Anything done to the stinger affects the number of degrees added to the antenna by the coil to stinger interface. For a given element delta length, the number-of-degrees-added effect is greater than the number- of-degrees-subtracted effect." The 4 inch spring is approximately 0.646 degrees long at 5.3 MHz.

Z02 has not changed. Z01B has not changed. [The L/D ratios for these components have remained the same and the Zo of each element is therefore the same.] The physical characteristics of 0.646 have not changed. The Capacitance to the coil is the same in either case. Only the location has changed. Do you claim the complex impedance of 0.646[case 1] is different from the complex impedance of 0.646[case 2]. Why? Or, do you claim the net Z01B + 0.646[Case 1} is now electrically longer, in degrees, than Z01A + 0.646[case 2]. Why? |
