I don't have my CQ mags at the new QTH yet, so I can't check the
exact issue for the date that this antenna appeared on the cover, but,
if I recall correctly, it was 13 elements on a 156 ft boom. My
modeling on this antenna indicated that it was probably too high--
resulting in a null at some important elevation angles.
And the W6TSW "multi-support" fixed Yagi was covered in some detail
many years later in CQ magazine as well.
