I usually get ferrites and iron cores from CWS Bytemark. Newark carries some interesting ones, although they are not my first go-to. I have also gotten a few from Amidon.

I don't think the key was beads-on-coax, but more the material and the amount of material. There is about a foot and half of beads on the choke right at the radio connector, it's really sorta awkward since my radio is under the passenger seat and the coax is poking out like a tentacle. :-)

I do plan on re-turning the choke using known material toroids or maybe binocular cores and putting one on each connector (probably mix 67 for the VHF) and one at each end of the HF feedline. Putting the choke in or wrapping it with something to protect it from getting broken.

Common coax cable type outer diameters.

"Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security. " --Albert Einstein
