Price, Quality, Service - Get all three

​

The Mini-Windom is a compact, high-performance, multi-band dipole variant designed for amateur radio enthusiasts who value portability, durability, and efficiency. While we love the simplicity of a resonant half-wave dipole, the Mini-Windom steps up for those needing multi-band capability, especially for low-power (<100 Watts) and DX operations. Optimized for 100 Watts SSB (40 CW / 25 Digital) and frequencies above 7 MHz, this antenna delivers exceptional performance for base stations or portable setups. This is a complete and ready to use antenna system made in the USA by hams for hams.What You Get for $149.95:
  • Mini-Windom Antenna: An off-center fed dipole with an integrated 4:1 Ruthroff voltage balun at the apex for 200-ohm impedance matching.
  • Vertical Radiator Section: 10-foot RG58 coax with BNC connectors, placed between the balun and RF choke, enabling low-angle radiation for DX.
  • Portable RF Choke: Miniaturized, lightweight, and designed for 100 watts SSB or less, connected at the feed point with an SO239 connector.
  • Protective Accessories: Three end-protector caps for connectors.
  • Camouflage Pouch: 7.5" x 10" drawstring bag for easy storage.
  • Free Shipping: Within the United States.
  • 60-Day Free Returns.
Made in America with materials sourced from U.S. suppliers, this antenna is lightweight, rugged, and built to last. Unlike traditional off-center fed dipoles, the Mini-Windom uses a voltage balun and a radiating 10-foot feedline section, offering unique advantages for low-power DX. Its compact size and rugged design make it a high-value alternative to more expensive, fragile antennas. Whether you're chasing DX or setting up a portable station, the Mini-Windom delivers.Key Features:
  • Multi-Band Operation: Covers 40 through 6 meters (tuner required).
  • Optimized for DX: The 4:1 Ruthroff balun and radiating feedline section enhance low-angle radiation, ideal for long-distance contacts, especially to Europe, Central/South America, and nearby Asian stations.
  • Portable and Durable: Perfect for field operations, stealth setups, or small base stations. Easily fits in a backpack or glove box.
  • High-Quality Construction: Uses 18 AWG UL1007 elements, a Fair-Rite FT140-43 toroid for the balun, and an FT-140-43 toroid with 14-turn winding for the RF choke.
  • Requires a tuner. Most internal tuners will suffice but a wide-range tuner may be needed for certain bands.
Performance:Tested with a Yaesu FT-450D, LDG Z11 tuner, and 30 feet of RG-8X coax, the Mini-Windom achieves 1.1–1.5 SWR across 40–6 meters when strung 30–35 feet above ground. Screen captures of PSK reporter maps (included in photos) showcase its effectiveness for DX. This antenna is labor-intensive to produce, so only limited quantities are available. Check out field operations and ham radio content on YouTube from creators like Ham Radio Concepts and Outdoors on the Air.
