I have coax cable that I'd like to use, but can't find anything with a web search (google and ask.com). The _only_ marking is TVC-202970 There are no connectors crimped on, and I don't know where I got it. I'd like to know if it's 50 or 75 ohm, at least.
If there are no markings on it, chances are it is cheap, counterfeit, made in China crap. I would throw just it away.
Sounds like it's Television Coax, which is mostly 75 Ohm except for HD CATV or Hi-Speed Internet which is 50 Ohm. There's a company called "TVC" that makes a lot of coaxial products for TV. Not sure if this would be one of them.
