[RFI] Spectrum Cable Boxes

Anyone on here have experience RF shielding a Spectrum Cable box? I have
tried all sorts of RF chokes (Material 31 1-300mHz) on the power, HDMI and
coax inputs with very little success. Pretty much any band wipes out the
cable boxes. Its not a proximity effect to the antenna as the 80 meter
antenna is at 80 feet and about 50 feet away from the house. Also, I must
point out that the previous cable boxes did not have these issues. So I am
fairly confident this is an RF shielding/filtering issue with the boxes.
In speaking with Spectrum, I could not reach anyone in a technical
department that has RFI experience. Next step and test is wrapping the
boxes with aluminum foil, or cutting the cord.
Thanks for any suggestions.
