Rick,
I don't see a conflict with what I've written on this topic. Unless
you're expecting a complete treatise on the topic in every email. :)
I've repeatedly posted links to a complete discussion of these issues. A
couple of posts back in this thread, I specifically said that the
primary reason for using LARGER coax is that the resistance is lower
because the shield and conductor diameters are greater, and that skin
effect is directly related to conductor diameter. Several posters,
including me, noted the relationship between frequency and conductor
resistance. Must every concept be repeated in every post in a long thread?

Resistance at RF is a multiple of the DC resistance, but
the multiple depends on the conductor diameter and frequency.
