Just think of the SuperLoop. It has served on countless DX'peditions, worked hundreds of countries from the backyards of DX'ers all over the world and then imagine an antenna half the size of the original and optimized on 40 and 20 meters. All of that incredible performance is now concentrated on 40 and 20 meters. The SuperLoop 40™ offers all the gain of a full-wave loop on 40 meters and the outstanding performance of a Bi-square on 20 meters. And, if that isn't enough, all the higher frequency bands thrown into bargain. Wait until you see what this antenna can do on 10 meters.

The SuperLoop 40 uses the same outstanding technology as the SuperLoop 80™. The SuperLoop 40™ is a high performance, full size, full-wave, 40 meter loop antenna. On 20 meters the SuperLoop 40™ coverts itself into a 2 wavelength open loop or Bi-Square. The stub in the top leg of the antenna opens the loop when operating on 20 meters and selected other bands. This improves the antenna's radiation pattern and matching. Its gain is about 2 dB on 40 meters and around 4 dB on 20 meters, but it will seem much higher due to the incredibly low angle radiation pattern.

The Dedicated Matching Unit, along with all the other components in the antenna work together to provide a well managed SWR on all bands. While the SWR is not below 2:1, it is low enough to permit the use of coaxial cable. System losses are low.

It will be hard to beat the SuperLoop 40™ with anything short of an expensive tower and beam. Combine multiband operation, coax feed, gain on all bands, and the SuperLoop 40™ the obvious choice in a small profile multi-band DX loop antenna system.


  • All bands 40 - 10 meters
  • Small size, this antenna will fit almost anywhere!
  • Low noise
  • Automatic switching between Loop and Bi-Square modes.
  • 50 Ohm Feed
  • Exceptional Performance
  • Superb Receive antenna - SWLs take note
  • All parts, DMU, ready to go. Solder only two wires.
  • Easy to follow instructions
  • A tuner is required on all bands. Most internal tuners in newer radios will tune the SuperLoop 40™ on all bands.
