Topband: Waller Flag Question

Very interesting, that is my presentation, but my updated early terminated loop reference was from Harold H. Beverage patent applied 1938 and issue 1941 owned by RCA

U.S. Patent 2,247,743 Jul 1, 1941 Broadband Uni-directional Shortwave Antenna

Yes, the HWF is really a Beverage antenna. Hehehe.

Would you send me more information so I can update my History of the Flag antenna?

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.
