The coil data is: ~6" dia, ~6.7" long, 26.5 T, seems very close to 4 TPI. Looks to be #14 solid wire. Hmmm, dare I plunge into the next, obvious question? Provide the Velocity Factor and Characteristic Impedance per the formulas you offered: Tom Donaly wrote: What's the formula, Cecil? http://www.ttr.com/TELSIKS2001-MASTER-1.pdf equation (32) The velocity factor can also be measured from the self- resonant frequency at 1/4WL. VF = 0.25(1/f) I suppose you also have something that will tell us how to find your coil's characteristic impedance; o.k., out with it. http://www.ttr.com/TELSIKS2001-MASTER-1.pdf equation (43) and we can then achieve closure by comparing the same results with Reggie's formulas. |
