1. Cut off the outer sheath of the coaxial cable by the length shown in
the figure to left. Take care not to damage the external conductor.
2. Fix the nut, washer, gasket, and clamp to the coaxial cable as
shown in the figure to left and unfasten the external conductor.
3. Cut the external conductor, insulator, and internal conductor by the
length shown in the figure to left. Cut off the external conductor to
the same length as that of the tapered section of the clamp, and
smooth it down to the clamp.
4. Solder the contact to the internal conductor. Note the following.
• Make sure that the soldered part does not swell.
• Make sure that there is no gap between the connector and the
cable insulator and they do not cut into each other.
• To prevent the insulator from deformation, solder the contact
quickly.
5. Insert the contact assembled in the step 4. into the plug shell
and screw the nut into the plug shell.
