[time-nuts] 75Z vs 50Z for GPS receivers

[Bill Hawkins]

Dave Brown said, in part,

"The characteristic impedance of a transmission
line, in purely general terms, is given by the square root of R plus
jw L divided by G plus jw C, with the usual meaning for symbols used."

Well, I know most of those symbols, but what's gravity (G) doing in
that equation? By dimensional analysis, G must be conductance, so we
have Ohms^2 under the root, and the answer is in Ohms.

So, what is R the resistance of, and what has conductance G?
