This cable is attatched to a digital antenna I have and I have no idea what it is. I thought I knew most AV connectors. looks recessed like a co-axial but has a thick prong like a composite. Very confused. Thanks for any advice.
Pretty sure this is just an RCA connector, albeit with a short pin or extended sleeve. You're plugging it into a standard RCA jack, right? I recall running into something similar before, thinking that it was just a manufacturer quirk (certainly most RCA connectors have the protruding pin which tends to auto-center upon insertion).
It's technically incorrect to call it "composite", that's just what they're used for in a typical home AV setup; also this is technically a "co-axial" connector. Cables and connectors are different things.
@quantris: I've tried it in every port I have on my TV. Prong is too small for RCA and too thick for the coax antenna thing.
I checked the back of my consoles, and yeah, it looks just like the SNES A/V plug that goes to the second gen version (the rounded, smaller one). Now that connector you're showing in the OP, that is directly attached to the digital antenna? Or does it have another end?
Looks like a male Belling-Lee aka (arial antenna) connector.
This is correct, and since this is going into an antenna it's most likely a coax cable.
This is also the traditional RF cable for most European countries I believe.
