I hope that thread improves, as from reading the first few pages, there are some fairly intelligent people, missing the point.

Canare RCAPs are a multi-part connector, you crimp the centre pin (which is the centre pin from their BNCs) and that then plugs into the RCA body itself.

The actual pin that makes contact with the socket is not the same pin that attaches to the cable, there is an additional interface, whose characteristics are most likely tailored to bring the CI up to the magic 75R figure.
