Hello.

I've read some comments and article telling that current of outer conductor (shield) of the coaxial cable only flow on inner layer of the conductor (layer facing central conductor of the cable), rather than use of whole conductor.

Is it really true? If so, how it is possible? what make it to be like that?

Thanks to read!
