If it's HF RF, you'll need something like the choke(s) in my HF 
Transmitting Choke Cookbook. Just clamping cores on the cables is 
unlikely to do much. k9yc.com/publish.htm  You don't need to use the 
same cable, but the turns should go through the cores in order, not 
scrambled, and with the smallest practical turn diameter.
