Hi guys This is a collection of paper I was able to put together, please it is a working in progress and new entries are welcome. My eye is not doing well and it is hard for me to type, so this is a copy and paste.
1919 March 5, 1919, Roy A. Weagant, Chief Engineer of the Marconi Wireless Telegraph Co. of America, delivered a paper describing in detail his apparatus for the elimination of the great bug-bear of transoceanic wireless communication --static interference. >> http://infoage.org/html/wa-1919-04-p11.html 1938 Harold Beverage invented wide band receiver antenna, loaded loop. The present invention relates to short wave antennas and, more particularly, to antennas for receiving horizontally polarized waves over a wide band of frequencies. An object of the present invention is to enable the reception of horizontally polarized signals over a wide band of frequencies such-as is at present used in television. https://docs.google.com/viewer?url=patentimages.storage.googleapis.com/pdfs/US2247743.pdf 1940. Nearly all the newly re-invented compact receive antennas derive from the terminated loop, the earliest reference was in an appallingly mimeographed prewar training manual of W3EEE Dad‘s 1973 COMMUNICATIONS 74 CONFERENCE BRIGHTON Wednesday, June 5 1974 —Session 5 Equipment Design Paper 5.3: Loop Antennas for HF Reception Contributed by: B.S. Collins, C & S Antennas Ltd., 1995 JF1DMQ wrote an earlier article about the Flag antenna in November 1995 in a Japanese magazine. His was only 3.3 feet by 16.4 feet long (1 by 5 m). K6SE's 160m optimized versions are 14 by 29 feet (4.3 by 8.8m). 1995 "Is This EWE for You?"
