Radio Engineering and Radio Engineer's Handbook are two different critters. My
copy of Radio Engineering is the third edition and the pertinent information is
on p.20.
To partially quote: "Thus, with a flat-strip conductor, the current flows
primarily along the edges."

You're going to have to explain that to a whole lot of high current flat wound
inductors & transformers.
What are you referencing? The only Terman I have handy is Radio Engineer's
Handbook.

RF does not flow on the entire surface of flat copper tape (Electronic and
Radio Engineering by Frederick E. Terman 4th Edition, p 22). The RF current
only flows on the outside edges of the strip, not on the middle outside
surfaces. Think of looking at the end of a longitudinal slice out of a solid
copper rod.

Sounds like you're following the rules. You might consider flat copper tape
instead of wire for bonding. Lightning is an RF event and currents will be
confined to the outside surfaces of the conductors. Consequently, the surface
area rather than volume of the conductor is what matters most. The conductors
on one of the original transmission lines from Hoover Dam to Los Angeles were
hollow.
