There are more, check out the Fair-Rite and Mouser sites: http://www.fair-rite.com http://www.mouser.com Note you can search the Mouser site with the Fair-Rite part #'s, which makes checking multiple sources easier. 2631102002 0.505" ID x 1.125" Solid, "big-bead" style (cheap!) 0431164181 0.515" ID x 1.550" Snap-On (easier to use) I chose these as examples because they are the correct size for 0.5" cables, like RG-8 and its many variants. You can also get a couple of turns of 2x#10 through them for choking DC supplies. PLEASE check the Fair-Rite catalog pages to see if they have something that will specifically fit your needs. The above are just "generic" suggestions. Remember, the more turns you can get around the core, the higher the choking impedance and the fewer cores you'll need.
