DX Engineering RFI Suppression Snap-On Ferrite Beads act as an RF choke when placed around a current-carrying conductor. They offer a convenient, and yet inexpensive and effective means of RF shielding, parasitic suppression, and RF decoupling. Their special ferrite mix is ideal at HF and VHF and effectively decouples unwanted RF from automobile ignition systems, speaker wires, control cables, or other wires and cables suspected to be absorbing or radiating RF interference. DX Engineering RFI Suppression Beads simply snap on, so no cutting is needed to install.
Additional features include:
* Reduce or eliminate ignition/injector noise
* 3 S-units improvement not uncommon
* Hear many more stations
* 31-mix is optimal for HF and VHF
* Mobile, home, or shack use--any RFI application
