Materials Needed: RG59 Coaxial Cable, BNC Plugs, Coaxial Cable Stripping Tool, BNC Crimp Tool.

To make up a BNC cable first, using your cable stripping tool, strip about 20mm of the black outer cover from the cable exposing the copper braid, inner insulation and centre conductor.  Next place the BNC Ferrule onto the cable.  Then fold the copper braid backwards onto the black outer cover to reveal the white insulating material.  About 4mm of the white insulating material should now be removed and the centre pin of the BNC placed onto the centre conductor.  Using your BNC crimping tool, crimp the centre pin onto the centre conductor.  Now the BNC plug can be placed onto the cable, allowing the centre pin to be inserted through the BNC plug.  You should hear a click once the centre pin is inserted properly, be a snug fit and the BNC plug should hold the white insulating material.  You can now fold the copper braid over the BNC. place the ferrule over the copper braid and crimp using your crimp tool.  If any copper braids still showing, it can be trimmed away with an appropriate tool.

The below image will show you how to attach a crimp-on BNC Connector to a RG59 Coaxial Cable.
