Directions First, slide the metal barrel supplied with the connectors you have down the coaxial cable, it is important that you do this first. You will then need to strip the PVC outer layer without damaging the core inside, you can do this with one of our cable strippers but if you are confident with a pair of snips/pliers, you can strip the outer layer away with one of those. Having removed enough insulation, you will see the silver/copper coloured wire net/braid around the internal insulation. Fold this braiding back over the outer PVC layer and then remove any foil shielding. You can now insert a connector over the top of the prepared cable so that the internal insulation is flush with the hole in the connector, insert the cable into the crimp tool and close all the way. Now trim any excess copper away from the top of the connector (depending on the type of connector used). Your coaxial connector is now securely crimped in place.
