So how many nanoseconds does that 36.6 degree phase shift represent?


As far as impedance discontinuity *points* go, a nonsense
question.

How many nanoseconds does it take for a signal to travel
through a dimensionless point???? Well, let's see. What
is the speed of light multiplied by zero? Hmmmm, that's
a really tough one.

At any instant of time the forward voltage on
one side of the discontinuity *point* has a relative phase
difference from the forward voltage on the other side of
the *point*. This relative phase difference is constant as
long as the conditions remain unchanged.

The reason that it takes nanoseconds for a signal to travel
through a 75m Bugcatcher loading coil is that the coil is
NOT a dimensionless point. Mine occupies almost 200 cubic
inches. Loading coils with zero dimensions exist *only* in
the human mind and are impossible in reality.

Is "reality" confined to the speed of our brains or the
reflexes of our muscles or vision capabilities of our eyes?
To create is to produce to take the place of "nothing"
