Steve, except when it (correctly) reads 1:1, doesn't an SWR meter always
have to contend with "complex impedances?"
Even if the antenna impedance is purely resistive, if the input Z of the
antenna doesn't agree with the Zo of the feedline, then the SWR will not
be 1:1. And the input Z to the line will be complex. In the real world,
the input Z to any feedline is almost always guaranteed to be complex,
even at "resonance" for the antenna.
What am I missing here?
