W3EDP Antenna

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
