[Elecraft] KPA500 High Reflected Power Fault

[Don Wilhelm]

  The one piece of information that is left out of most discussions 
about multiband antennas is the feedline length.
The feedline acts as an impedance transformer since it is not matched to 
the antenna.  Used in that way, the feedline type and length become an 
important factor.  That is why some work on some bands while others with 
the same radiator length do not work the same.
