Apr 21, 2021 · The Carolina Windom is a variation of the OCF with a choke balun (line isolator) placed 22 feet below the 4:1 balun on an 80-10m off-center fed antenna. This allows the 22 foot vertical section of feedline to act as a radiator.

The basic Windom antenna is an off-center fed flat top antenna having a length of one half wave at its fundamental design frequency — usually 80 meters.

The Windom antenna is an off-center fed dipole with an unbalanced coax feedline. In 1937, the Windom was first described as a compromise multiband antenna. The antenna can be employed on 80, 40, 20 and 10m with considerable, though acceptable levels of VSWR.

THE K4TR OFF-CENTER FED "CLASSIC WINDOM WIRE" 80-10 METERS A Multiband Antenna That Enjoyed Considerable Popularity in The 1930's was Named for the Amateur Who Wrote a Comprehensive Article About It. The Antenna Consists Of A Half Wave Length Antenna on the Lowest Frequencey to Used, With a "Single Wire Feeder" Connected Off Center.

A windom antenna is a single-wire-fed antenna which is worked against ground. It's a grounded vertical wire connected to a horizontal portion acting as a top hat capacitance. On the other hand, an OCF dipole is an ungrounded dipole antenna fed with twin-conductor line, either coaxial or open wire parallel conductors.

The Carolina windom antenna is a vastly improved and much more effective antenna than the old windom of the 1930's. Here is why and how it works.

Dec 22, 2014 · In the middle 1920s Loren Windom operated 8GZ/8ZG in the Columbus, Ohio, area. Windom ran high power for that time (250 watts) and was considered the technical bellwether of Columbus hams, as he was an active experimenter, working …

Our tests have shown that when compared to dipole or long-wire antennas, the background noise with a balanced termination, folded dipole (BTFD) antenna is not only much lower, but allows weak signals normally not heard, to be audible and therefore legible.

Jan 21, 2025 · The 4-band Fritzel model FD4 is a special version of a Windom antenna. It is a half-wave long on the lowest frequency, and is fed from a coax cable through a transformer inserted in the wire at one-third from one end
