yes, that is coaxial cable so you might have a hard time soldering it. The center conductor is easy to solder but the braid can be a pain sometimes.

If your already buying a terminated cable then you can just get female to female rca ends to put on there so that you can couple it to another cable. They also make keystone jacks like this.
