Butternut HF5B 5-Band Butterfly Beam Antenna

Five popular HF bands 20, 17, 15, 12 and 10 meters in a rotatable, two element beam? No Lossy traps? YES! Butternut’s innovative HF5B offers exactly that! Especially designed for the amateur with limited space, it offers significant improvement over omni-directional antennas, with useful forward gain and good front-to-side and front-to-back rejection of QRM.
