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. >>

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.

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

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).

QST January, 1996, p. 32) both by WA2WVL.
1996
The Pennant was originated by EA3VYand optimized for 160 meters by K6SE, who
first wrote about them on the Top Band Reflector in 1998
