As others have noted, ferrites will help attenuate RFI ** IF ** you own the
offending source and can choke it for radiation or choke your own wiring
against common-mode pickup.
However, I find that RFI generators over which I have no control are the
predominant sources at my QTH after all the local offenders are quenched,
e.g. arcs on tie wires or transformer connections in the electricity
distribution wiring in my neighborhood and beyond, and RF egress from
defected coax sheaths in the cable distribution network.
Interestingly, the local power company RFI hunter told me that he works hand
in glove with the cable companies because the cable customers report TV,
internet and telephone interference that is traced to power line arc
generators making ingress to the cable network - both utilities find the
weak points in their respective systems.
