Installing coax cable connector end fittings is not very difficult. It may take a little practice but it is a simple process once you get the hang of it. I suggest that when purchasing coax cable end connectors buy a few extra. Once you crimp or compress a coax cable end it can't be used again.
 
1.Adjust the wire strippers so the first cut is down to the center copper wire. Adjust the second cut so it cuts through the rubber jacket only but not through the wire braiding just below the rubber jacket. This may take several attempts to get the tool adjusted just right.

2.With the stripper properly adjusted insert the cable into the strippers so the end of the cable is flush with the edge of the stripper. Spin the stripper around the cable until it turns freely. Pull the stripper away from the cable while lightly squeezing the jaws of the stripper onto the cable. You should now have a cable ready to install a connector.
 
3.Slide the proper coax cable connector onto the cable. This sometimes requires a pair of pliers to grip the connector if the fitting is stubborn is does not want to slide on easily.

4.With the coax cable connector properly fitted to the cable insert it into the crimp tool as shown at right. When the connector is properly in place squeeze the handle to crimp the connector onto the cable. The first slot of the tool is for RG 59 cable and the second slot (as shown) is for RG 6 coax cable.
 
5.With the compression connector properly fitted to the cable insert the fitting into the compression tool copper wire first as shown at right. When the connector is in place squeeze the handle to compress the connector onto the cable.
