Can we make a physically small "phase reversing coil" that has 180
degree phase shift between its ends? If so, how?

Thanks, Cecil. My copy of Kraus is new and I`d not yet read page 824.
Kraus says:

"The coil may also be thought of as a coiled-up halfwave element."

I like his preceding sentence:

"Here the elements present a high impedance to the coil which may be
resonated without external capacitance due to its distributed
capacitance."

A "phase reversing coil" does present a 180-degree phase shift between
its ends.
