Can't imagine someone trying to design for only one
mode. The question pertained to "effect". The other
effect are differences in impedance between even and
odd being almost 30%. Something to consider. Well,
maybe since no one has brought it up.

I didn't hear about even or odd mode impedances until
10 years after the university and that was over 15 years
ago. And I've got more than enough of the grey hair.

But thanks for trying to call me a "younger guy".

Much appreciated!!!
