Re: [IRCA] KAZ versus Pennant/Flag
Fascinating discussion. I have come to use the 160â DKAZ exclusively for my bi-annual trips to Grayland and Lubec.
It is a GREAT âcoastalâ antenna - where the DX is all in front of you and the crap is all behind you.
As Nick points out it can be more critical where you point the null vs. the main lobe of the antenna.
I wonder Chuck if you could ad a column for mid-band to your EZNEC chart?
As others have already stated, I too have found the DKAZ at any length above 120â is a great mid-band antenna with various less-than-perfect features on both high and low end, a little less F/B and a little less sensitivity respectively.
That Kaz is hearing low band DUs from IL on a 120â DKAZ says it all. Whatever the less-than-perfect features of the DKAZ it is still the best all-âround, single structure, outdoor MW antenna Iâve ever used. Iâve put up and taken down over 30 in the past several years in various places and by now I think I could probably do it in the dark â in fact I have more than once in Maine arriving after 4pm sunset in November!
Thanks for coming up with the design Neil!
