I suppose we all agree that the DKAZ has nailed some great catches.

My goal was to point out a shortcoming, not to say that it can't hear DX a la Colombia / Venezuela / Nicaragua.

**Anecdotal evidence alert**

I guess I'll risk getting attacked with fruit as well. I got into the AM
DX part of the hobby only two years ago, so I didn't get the memo about
140 feet being too short. I have lots of great catches from here in the
Midwest on the shorter DKAZ made from those instructions, like Colombia,
Venezuela and Nicaragua, a very tentative snippet from Brazil, and I'm
pretty sure I have Tahiti on one of the recordings I made before they
went off the air. (I just have to remember which hard drive it's on...)

For most of that time though I have been using the FLG100LN-2, which I'm
sure makes a difference. I also didn't make it reversible or anything. I
put up a "test" antenna to see how it would perform, using some coax and
my first hand-made transformer (on a toroid my brother had lying about
at his workplace, so I don't even know what material it is), and have
been using it ever since, manually switching it from N-S to E-W. But
like driving a stick shift, you only do it for so long and then you want
an automatic, so I might try to make it reversible (and add a second one
if I can figure out where to put it, to cover all directions).

SOME FIELD INFORMATION ON THE DOUBLE DELTA (D KAZ) ANTENNA<http://www.durenberger.com/documents/DKAZ070314.pdf>
www.durenberger.com
The D‐Kaz antenna for MW (and well above) is a Double‐Delta variant, as seen below. The “self‐impedance” of the D‐Kaz is around 1000 ohms at corners “A” and “B.” The null‐pot at 2000 ohms gives good range.
