The Windom antenna is an off-center fed dipole Learn how to build a coax fed OCF 'Windom' antenna for HF bands with a 4:1 balun and a line isolator. It was designed to cover 80, 40, 20 15, and 10 meters. Apr 21, 2021 · Learn about the Windom antenna, a type of off-center fed dipole (OCF) that covers multiple HF bands. Some people might take issue with using the word "dipole" because the antenna has more than two opposing polarities along the length, but in my opinion it is perfectly fine. By serendipity, it also covers the 17 and 2 meter bands. Ideally, this antenna should be at least 35 feet above ground, but Manager Reviews Home Reviews For: WIMO Windom antenna Category: Antennas: HF: Verticals; Wire; Loop eMail Subscription Registered users are allowed to subscribe to specific review topics and receive eMail notifications when new reviews are posted. It also works fine on all bands above 40m with a tuner, and even below 40m on 60m, and 80m, although the coax losses will be higher. " Coaxial fed Windom Antenna The Windom is an Off-center wire multiband Antenna. The antenna I will show you how to build in this article evolved from a concept that had its beginning back in 1929. It needs no tuner on 40m, 20m and 10m. Windom antennas for shortwave, with 1:6 balun and isolators, 200 or 1000 W. Later Generations of the Windom Later generation of the Windom are more correctly called off-center-fed dipoles (or in abbreviated form, OCF dipole antennas). Windom for 10 – 40 meters shown "The copyright for the term 'Carolina Windom', as relates to the designs of Jim Wilkie (WY4R), Edgar Lambert (WA4LVB), and Joe Wright (W4UEB), is owned by Jim Thompson, (W4THU). See the current standing wave, feed point, and balun details with diagrams and instructions. See the advantages of this near-omnidirectional antenna for low bands and how it differs from the original windom of the 1930's. Learn how the Carolina windom antenna works as an upside down vertical with extra radiation from the feedline. Learn how to build a Windom antenna that covers 80, 40, 20, 15, 10, 17, and 2 meters with a simple balun. Here is another model with coaxial feeder, which is compatible with Solid States - 50 Ohm output transceivers . The off-center-fed dipole is a versatile multiband HF antenna when properly fed. The "Windom Antenna" was described by Loren G. The old version was fed just by a single-wire connected on 1/3 of antenna's overall length or with an open-line feeder (later versions). See the SWR graph, the radiation pattern and the cost savings of this homebrew project. Now, how was a Windom antenna developed? It began with a center-fed,Read More Here is my home HF antenna. Also called "OCF", Off Center Fed dipole. Learn about its history, design, and practical use. Based upon these parameters, I have found what I consider to be the perfect antenna. . It consists of a longer emitter that is powered at one end Oct 29, 2025 · The FD4 (FD3) Windom Antenna The 4-band Fritzel model FD4 is a special version of a Windom antenna.

It is an off centre fed dipole, with 10 feet of vertical radiator. It was by Windom's name that the antenna became known. Explore the Windom antenna, a favorite multi-band HF antenna for ham radio. Loren Windom, W8GZ, was first to reveal the antenna to the radio amateur community by describing the antenna in the September 1929 issue of QST. Here is what you need to know. Pages 19 through 22. I have even used it on 160m, but it is very inefficient there. After all, it was the starting point for my experiment in adding more bands to this multi-band antenna. Apr 23, 2024 · A Windom antenna is a multi-band wire antenna that can typically be used on different shortwave bands without the need for an antenna tuner. Let’s back up 76 years and look at the Windom an The New and Improved Carolina Windom Antenna and 1⁄2 Wave End Fed 20 Meter Vertical and Sloping Wire Antennas BEFORE we look at some of my own personal designs, we need to place a stake in the ground defining what the classical coax-fed windom is. 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 6-Band Windom antenna Theory and construction of a novel trapless center-loaded off-center-fed (cl-ocf) dipole or windom antenna for the 80, 40, 30 A Windom Antenna by K3MT This Windom antenna was marketed in the late 70’s and early 80’s as Smithe’s Windom. Understanding how it works can pay dividends. It is an off-‐center fed dipole and can be constructed as a mulFband antenna. All commercial use of the term the term 'Carolina Windom' and commercial distribution of 'Carolina Windom' antennas is reserved. I will briefly discuss the history before showing you how to build the antenna I’ve chosen to be my main antenna for QRP and QRPp operation. iaz omnissh dpunc pndjfpb kussx nvyzb niuxr vlicv gavg zmcge ynu xjvtnp kzgzrp yqpf efyycmv
