Can anyone tell me what a 75 ohm coaxial plug pin cable is?

Thanks

    Hello,
    Are you looking for an RCA plug that will go on the end of a coaxial cable and have a characteristic impedance of 75 ohms? Not quite sure what you're looking for?
    Cheers, Ken

    Isn't that what you plug your TV into an antenna with?

    Are you reading the bluejeans descriptions?

    If yes, they're using plug pin to refer to an RCA connector. A 75 ohm cable with rca connectors on it would be a digital audio cable. SPDIF!

    Honestly, you're question is not clear. What are you trying to do?

    Hello,
    If it is a true digital cable, the RCA plug itself would have to have a 75 ohm impedance as well as the cable. The dielectric used in the RCA plug would have to have a 75 ohm impedance at RF.
    Cheers, Ken

    Here is RCA plug (can be 75ohm) on the left and BNC (more standard 75ohm) on the right.

    I think the last picture on the left is what I am talking about. This is the EXACT language from the B&K manual for connecting the AVR monitor out to the monitor so I can get the on screen set up menu. It says that this is the only output that will work...not S-video, not component...

    sorry for lack of clarity, but that is the phrase that is used...it sounds like a traditional video cable, like for cable tv, but with an RCA plug on the end...and not a composite video connector...
