[RFI] Air Gig?

[JW]

Ah. The well-known (among some of us) G-Line or Goubau line single-wire transmission line.
https://en.wikipedia.org/wiki/Goubau_line

The secret is a thin layer of dielectric on the surface of a conductor (yielding a slower-than-light propagation velocity CLOSE to the wire) and the RF energy is then 'loaded' onto the wire via "launchers" (coax to horn transitions basically) on each end.
Think groundwave propagation close to the earth on the lower frequency bands. 
Something old is "new all over again."
