Glad to see you posting again, Art.

Kraus produced an organization chart of antennas on page 56 of the 3rd
edition of "Antennas". In the Kraus plan, the "Yagi-Uda" is among the
"End Fires".

The topic is: "Yagi Antenna Question".

Roy responded with:
"Suppose you have a two-element driven array with the elements spaced a
quarter wave apart and 90 degrees our of phase."

This driven antenna produces a nice null to the rear as a Yagi can, but
the Yagi is a parasitic array, not a driven array.
