Re: [IRCA] KAZ versus Pennant/Flag

Kaz -


You were at the Yachats DXpedition in 2013 where I believe everyone felt the 20 x 140 DKAZ was somewhat deaf on the bottom end.

A recent 20 x 160 DKAZ yielded SDR files that one DXer is not even scanning below 700 kHz and I am not scanning below 800 kHz.

A DKAZ at Newfoundland last year produced more or less the same picture as the recent DKAZ.


All of this is substantiated by Perseus spectrums and theory which says there is a 27

A major advantage of the DKAZ is the significantly wider back null so that
more back end QRM is taken out or greatly reduced. Of course, the more
narrow beamwidth is very useful on crowded freqs and one reason I am able
to catch 2nd tier stations from west coast states here in IL.

Yeah, the don't have a ton of signal pickup at the low end, but logging 2CR
549 here in IL on Oct. 1 using only a 120 ft DKAZ should indicate a usable
antenna. Of course I amplify with the FLG100LN. Maybe sometime some DXer
with enough land will compare a 200ft+ DKAZ on the low end vs a more
typical size.

The problem with going huge is that high end F/B starts to suffer and the
beam also becomes wider in the upper part of the band. The DKAZ is a
compromise antenna and really not intended to cover a 3:1 bandwidth as well
as some of us would like. But the patterns and the DX I can log using it
put the single loop genre of antennas to shame at least here in IL.

Again I will stress amplification for any of the guys here considering
trying to squeeze in a smaller DKAZ.  73 KAZ
