[Elecraft] KAT500 antenna selection

[Rick Bates, NK7I]

I'll submit that the KAT500 was designed long before 630 meters was 
generally open and the values needed to present a low SWR are far larger 
than needed elsewhere.  Anything below 160M is a 'specialty' band that 
far fewer will attempt.  However you COULD go through the values that 
the KAT500 offers manually and see if something could work.

You could use an antenna analyzer in SWR mode (fixed freq not sweep) to 
tune the antenna at almost any frequency (at flea power, all legally).
