In the 1936 March issue of QST, Yardley Beers, W3AWH, described an antenna designed by his friend, Mr. H. J. Siegel, W3EDP. The design was based on the end-fed zep antenna as once trailed from Zeppelin Airships. The original design called for a 17 ft. counterpoise , a 67 ft. radiator and a matching unit to couple the antenna to the radio.
On 20 Meters it is 1.5 wavelengths
On 40 Meters it is 5/8 wavelength
On 80 Meters it is slightly less than 3/8 wavelength
I experimented alternating between a 67 ft (original design) and an 85 ft long wire radiator. Both wires tuned 10 – 80 meters.
The 85 ft wire tuned 10 – 160 meters. Performance may vary with your working conditions. Overall, the antenna seemed to perform the best on 40 – 10 meters
