Hi John

"your killin me...a pic, some equations, and some simulations would make it so clear...but you balked at a drawing last time...:-)"Jn

Yes it would have. But the way you draw and your handwriting make it so difficult to read. It remind me of first grade drawings one would hang on refrigerator door..LOL :)

One thing you mentioned that cleared up this matter pretty much. You said that for a wire pair, like a coax, or zip, the current goes down one wire, and back the other...since they are in series, each wire carries exactly the same current.

My original thinking was if one leg of pair is not the same gauge as the other leg, we will have different current flowing in each one. But now realizing that pair [in practical] are in series, then the current have to be the same in each leg, no matter what each gauge of wire is in each leg. So that answer my question about the imbalance..as far as a pair is concerned.

But as you said, since Jon's design is so unorthodox, one may have to step beyond tradition proven cable construction theories to explain its functionality.

On the final note, you said that twisting a pair of coax (like Jon's) will minimize the inductance of the run. Does that apply to coax pair only?
As I recall, you mentioned that twisting a pair does not reduced its inductance....since you measured a non twisted [parallel] pair with a twisted one, and the inductance remained the same.

Thanks.
