[TowerTalk] 2 el driven array

[Ken Hirschberg]

Dave and all -
Correct in all regards!  It might be useful to point out to those unfamiliar
with those arrays that the ZL and the HB9CV have cardioid patterns, compared
to the bi-directional patter of the 8JK.  Further, the ZL and HB9CV are
discussed on Cebik's web site.  The new 2D-40 from CAL-AV is a modern
derivative of the ZL / HB9CV, with some innovative phasing, matching, and
balancing.  It may be seen with an EZNEC3 comparison to a full-size 3-el 40M
