No ground, radials, or counterpoise is needed. A new 313 PF matching capacitor increases the matching range, and a high-efficiency butterfly capacitor has no lossy rotating contacts. Small magnetic loops are very quiet on receive. You’ll hardly notice static crashes. The high-quality design reduces QRM, overloading, and harmonics.


It’s perfect for apartments, antenna-restricted areas, and portable operations. Loops can be as small as 4′ for 17 – 10 m, 7′ for 20 – 15 m, 28′ for 60 – 40 m, and 50′ for 80 m. Loops don’t have to be pretty. Any shape will work!


Includes an easy-carry handle, a mount for a PCV loop support, and a tripod/mast mount.
