5 Fundamentals of Off Center Fed Dipoles

Off center fed dipoles OCFs are 1/2 wavelength wire antennas fed at neither the center nor the end

An off center fed ocf dipole

It's a dipole fed off center with a 4:1 balun at the offset feed point

Off Center Fed OCF dipole antenna

Permette di lavorare su piu' bande almeno per la fondamentale e le prime 2 armoniche con una efficienza accettabile

Off center feed dipole FD-4 for 160m

I took a pvc-tube with 50mm diameter and bring up 125 windings of 0,75mm² hvk standard isolated cable

Ocf Dipole Balun

Here is an enhanced balun for OCF dipole. The two toroids make the 1:4 impedance transformation

Windom dipoles

Known as OCF for off-center-dipole, or off center feed or simply Windom, it is an antenna with many variations

Windom off center fed

Later generation of the Windom are more correctly called off-center-fed dipoles or in abbreviated form, OCF dipole antennas
