Tom, Kaz,

>From the website Kaz provided it appears to be 4 active crossed-pair k9ay
loops:

Kaz,  am I correct in my understanding?  How did you feed the 4 pairs
of loops?  What were the phase relationships? How did you select directions?
That is, what control did you use?   Some details would be helpful.

My own experience with a single pair of crossed k9ay loops was that their
principal benefit was a sharp null.  If an offending station happened to
land within that null, it was useful.  Otherwise, it was not.  That led
me to conclude that a single rotatable k9ay loop was better.

At w2gd, the k9ay loop was far inferior to our beverages.  But having a
phased array of them might be highly useful, particularly if they are
steerable.
