This practical RFI Ferrite Kit is designed to reduce RF interference (RFI), noise, and unwanted common-mode RF around an HF transceiver.
The kit contains various ferrite clamps and a ferrite core, all made of ferrite material #31. These can be used to fit ferrite to power, antenna, USB, microphone, and possibly other connected cables to suppress unwanted RF currents.
