Antena multibanda fuera de centro
Known as "La 14%", "OCD", "OCF" for off-center-dipole, or off center feed or simply Windom, it is an antenna with many variations

A Multi-band Dipole
A half-wavelength long at the lowest frequency you hope to operate. Using the formula 468 ÷ Frequency in MHz

Antenna 1946 da Louis Varney G5RV
Due versioni, una lunga 15.4m che risuona dai 40 ai 10m ed una lunga il doppio 31m che permette un ottimo funzionamento anche in 80m

Antenna morgain 40-80 mt
Antenna bibanda per i 40-80 m. puo' essere fatta anche per i 10 e i 20 metri e puo' fornire ottime prestazioni anche sui 15 metri, ma il pregio rimane la lunghezza dei soli venti metri lineari
