The forward and reflected waves in transmission lines and antennae do not
affect each other by the principle of superposition (although they act
together to
give an apparent (and only apparent) standing wave.

Why, then, should a transducer connected to one end of a transmisison line
(such
as the PA stage of a TX) be affected by the apparent VSWR, as we know that
it is,
but why does not the principle of superposition apply in this case?

Just curious.
