Windom antenna
The Windom antenna is OCF off center fed

Off Center Feed Dipole or FD-4 on 160m
I took a pvc-tube with 50mm diameter and bring up 125 windings of 0,75mm² hvk standard isolated cable

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