That is very strange, not using the standard RF connectors...
Well to separate the coax into two leads, strip the coax outer cover back a couple of inches then at the the cut, use a pick or small screw driver to create an opening in the braided shield and pull the center lead through the opening. You should now have a braided copper lead and the insulated center lead to terminate at the connectors.
