I have used the little binocular balun ferrites found in the backs of VCR's
etc. (not really sure what you mean by calble TV baluns). I'm currently
using one as a power splitter in a txcvr I'm building. Although many will
swear upon heaps of old QST's, Ham Radio Magazines, etc. that one can never
be *absolutely* sure about unmarked ferrites, I think one can usually spot
type 43 (which is what I'm 99 & 44/100% sure these suckers are made of).
Type 43 just LOOKS a lot different than the other ferrite materials. Kinda
sparkly. Kinda special.
I would suggest winding some windings and try them out. If they don't work,
sell them as VHF bartenderators or some such hokum.
