[RFI] Winding RG-6 around a toroid

I am winding RG-6 around a toroid to keep RF out of my DirecTV box.
I'm having issues with signal levels on my DirecTV box and am not sure
about the cause.  Could wrapping the RG-6 around a toroid about a
dozen times cause this cable to provide a bad signal to the DirecTV
box?  Sure, a broken wire would do it, but I'm thinking more along the
lines of dielectric compression causing the impedance to change or
something like that.
