RCA refers to the type of connector whereas coax refers to the type of cable. They are not the same thing. For example, you can fit a coax cable with RCA connector or BNC connector. Therefore, comparing connector to cable really makes no sense.
"Just wondering how much info is not transmitted through a RCA verses a coax?"
what if Wig wanna use two of coaxial 75 ohm cable TV as RCA interconnect? It has outer skin shielding!!! This has brought up before but if any1 has done it disregarding of what's right or wrong on paper, please share.
