  • EMI/RFI Noise Suppression: Stops common mode current (CMC) and electromagnetic interference on data cables, coaxial feedlines, and antenna wires. Real users eliminated RF noise across the spectrum with a 9:1 balun setup.
  • High-Permeability Ferrite Material: Soft ferrite ring absorbs HF/RF interference instead of reflecting it; works across HF/VHF noise frequencies.
  • Built for Ham Radio & DIY: Ideal for baluns, ununs, EFHW matching, QDX/USB RF choking, vehicle HF installs, and Starlink 12V conversions (all verified in customer builds).
  • Spec: 42 x 24 x 16 mm (1.65 x 0.94 x 0.63 in). Package: 5 pcs, black. Generous 24mm inner diameter for easy cable threading (6+ turns of USB cable fits).
  • How to Use: Thread BOTH line & neutral through the ring for common-mode choking; wind 4-8 turns for stronger suppression. NOTE: This is a ferrite core, NOT a magnet; handle gently as ferrite can chip.
