This end-fed halfwave antenna from 2E0VOV is based on the popular "Par Endfedz" QRP multiband antenna. In this case, 2E0VOV used a FT140-43 toroid with a total of 16 windings and a 100 pf capacitor across the feed point. The 40 meter loading coil is made from 58 feet/17.68 meters of enamel wire wound tightly on a 20 mm form. A good, simple, inexpensive antenna suitable for portable and emergency operations.
