The best I recall that was a design by Laport. It was revered for its low elevation angle in RCA long distance HF work. I recall seeing details about in Johnston's Antenna Handbook (first edition) where it likely referenced an article in Proceedings of the IRE (late 30's probably) or Laport's book on Rhombic Antennas.
Previous ham attempts to use this design at VHF have not worked out as well as claimed. I wonder if it really was raised out of ground reflection effects on the test range. I've seen that with my wooden antennas that were too heavy to get up to the top of the pole at CSVHF... Where an EIA standard gain antenna capable of 7.7 dbd came up with 10 dbd...
