Well, where I used them on my phone lines here back when I had that problem, 
I actually turned the magnets around and rapped the wire around them, so 
they were end to end, and I was winding the wire around in a channel using 
the plastic outer shell as a retainer almost after I was done and that 
worked. I'm not saying that is right or anything, but I know that worked and 
that's the only time I ever have had any success with chokes, in most cases 
I find them way over rated.
