Re: [IRCA] Misek/Lankford/Ratzlaff proto test.



Chuck:  My guess is this practice was developed before folks tried phasing
against a directional MW antenna with real chops.  The "hot" end of a D-KAZ
is vernacular for the end you're orienting toward the desired signals; the
"null' end is fighting stuff from the back.  Practical F/B numbers across
the band are reaching well into the 30-db area.  If you then visualize the
resultant cardioid pickup it seems an omni phased against the D-Kaz would
also tend to suppress signals from the desired direction.

That opinion and $3.75 will get you a cup of cheap Seattle coffee :-))


Cheers!
