Default Dual-Z0 Stubs

While I was figuring out why Roy's "measurements"
were very accurate but virtually meaningless.


This is, of course, referring to Roy's "measurements"
of the "delay" through a 75m mobile loading coil as
being close to zero since there was "no measurable phase
shift" - as if the phase shift had anything to do with
the delay in a standing wave antenna. Hint: It doesn't!

Any person with a modicum of mathematics skill can
look at the following equation and know that there
is no phase shift relative to x in 1/4WL of wire or
coil.

Itot = Imax*cos(kx)*cos(wt)

Since Roy has known these details for more than
five years, I can only assume that he knows that
he is wrong but refuses to admit it - hoping that
his guru status will continue to promote his
old wives' tale.
