[RFI] RFI suppression cores for 147 MHz

[N1BUG]

I could use a little guidance. I have a case involving radiation 
from ethernet cables at 147 MHz. The common clamp-on cores seem to 
offer about 250-300 ohms ESR. It looks like I probably need a lot of 
them to clean this up, and there are several cables involved. Is 
there any core which would give more suppression with 2 or 3 turns 
of the cable through it? Thanks for any info or suggestions.
