I do see a discontinuity in a transmission line so the laws on
discontinuity do apply..

A #14 horizontal wire 30 feet above ground is a "single-
wire above-ground transmission line" line with a
Z0 = 138*log(4D/d) = 600 ohms where 'd' is the diameter
of the wire and 'D' is the height above ground. The ground
is the other half of the transmission line.

Common aurgument revolve about accounterbility for surrounding
fields. Your " transmission line" is hardly a conventional one to use
in such auguements
But then again my abilities in this area are not sufficient for
auguement or debate which is why I ask questions
