If you are going to use the TV connectors get the versions that connect to F connectors, as those i find are the best made ones, the ones for direct cable mount are in general pretty junky, but the F versions are typically turned plated brass. Then your cable just has to be either made with a solid core, or slip a copper wire end up the centre insulation for a way, to make a good contact with the stranded wires, and fit a F connector to the cable, and screw it together.
