Default Standing Waves (and Impedance)


Sorry, the last paragraph of my previous posting should have included
the word _causes_. It should have read:


Just caught Roy's second post about the mistaken belief that high SWR

_causes_ feedline radiation. It should be clear from the above
that higher-than-expected SWR and feedline radiation are two
separate *results* of unwanted common-mode currents. Once
again, SWR should not be mistaken for a cause.
