Bruce, ref to the link above there is a gap in the "History of the Flag Antenna" The earliest fef. to the Terminate loop I have found is in Keen’s Wireless Direction Finding 1927 Ed. Page 75. Keen describes a two turn resistance terminated loop used by Societe Francaicse Radio-Electrique. It resembles the K9AY and uses a similar operation to create a cardiode.
