On the "doublet" vs "dipole": at various times in history, the word "dipole" was taken by some to mean "quarter wave dipole", and doublet was a more general term for a balanced antenna. I will look in my older handbooks and see if there was a "singlet" (vertical? End fed?) in there. Sometimes I go looking in the 30's handbooks for vertical/Marconi style antennas and find nothing that I recognize at all, maybe I should be looking for singlets.
There are some complications... for decades the ARRL handbooks showed charts for doublets with strictly prescribed feedline lengths - I think they were intended to be optimizations while avoiding resonances in feedline but the reasoning behind the chart was never well explained, turning it into a "gospel" for many. What has thrown me for a loop many times is the "GP Antenna". In my gut I feel that "GP"="General Purpose" but sometimes I can eventually figure out that it means "Ground Plane".

A broadcast band SWL wanted a transformer for one. He furnished the basic antenna drawing that was a Delta Loop. Delta Loop antennas have been around for very many years. Anyway someone had published ,a Delta Loop, naming it a KAZ antenna. Seems to be mostly Broadcast band DX listeners. >From years ago: Was there an antenna called a doublet that was a basic dipole ? If someone is looking for a 160 meter DX delta loop antenna, I recommend the K6SE loop. Earl, K6SE (sk) is one of our 160 meter heroes. 73 Bruce-K1FZ www.qsl.net/k1fz/ < The "KAZ" receiving loop is related to the flag and pennant loops, and the < K9AY loop. _______________________________________________ It is undesirable to believe a proposition when there is no ground whatsoever for supposing it is true. - Bertrand Russell _______________________________________________ It is undesirable to believe a proposition when there is no ground whatsoever for supposing it is true. - Bertrand Russell
