If you want to purchase a good common-mode choke the one from DX Engineering is pretty good. Model FCC050-H05-A. See: http://www.dxengineering.com/search/product-line/dx-engineering-maxi-core-feedline-current-chokes Of course, you can make your own. They are quite easy. You are just coiling coax through the appropriate ferrite cores.
