Hello Bob -
The implementation will be interesting to watch. G-Line as it was
called guides a wave along a single conductor, and I believe that last time
I read about an amateur trying G-line on UHF was in the 70's. I remember seeing
this in old E&M books as a transmission line example. I wonder which
portion of their design is the subject of the patent. It will be important
to watch what frequencies they try to use for their test trials.
The interesting aspect is that AT&T will tout this as cutting-edge
and spend funds to develop a new technology yet totally ignore the
advantage of fiber-to-the-customer (or fiber-to-the-home) which is
available in many countries.

Thanks, Kermit. There's plenty of stuff on this system to be found on a Google search. It's in the 5G 28 GHz, 37 GHz, 39 GHz, and 64-71 GHz spectrum. Probably not going to be cheap! Nice chatting with you, tonight.
