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!

Id like to point out that it is quite feasible to phase a vertical;against a loop. It has been done for over 40 years. One variant of the idea was the LSCA, and reporints are / were available from the clubs about it.


But I didn't understand what is meant by the "hot end". Nor why phasing would affect what a DKAZ delivers.

I really need to do more reading on the topic. One of my interests
initially was to use phasing to eliminate RFI sources that had a
particular bearing. Now it's more to eliminate pest stations, like 1100
WTAM or 700 WLW or the Chicago stations, most of which are to the sides.

The "hot" end I'm assuming is the direction the D-Kaz is aimed at, which
in my case is to the south.

I've been thinking about trying out a superloop pointed West. Maybe that
would be a good one to use with the D-Kaz for phasing?
