N-type coaxial connections were initially designed for military applications. Deemed slightly more robust in adverse environments than standard coaxial cables, N-type connections can handle bandwidth in excess of 12 GHz. N-type connections are a little less available at the corner hardware store (and are not compatible with F-type jacks) but still can be found online. Used extensively by professional broadcasters, N-type connections can also be readily used at home with the appropriate equipment.

Cut the coaxial cable to length as needed.

Slide the backing nut, rubber washer, rubber gasket and clamp down the cable and out of the way.

Insert the end of the cable into the wire stripper, removing 1/2 inch of insulation.

Slide the white inner plastic dialectric tubing into the stripper, removing 3mm of this material.

Slide the clamp back up the cable. Fold the braided shielding evenly over the surface of the clamp.

Slide the nickel pin over the copper centre conductor, butting firmly against the white plastic dialectric. Apply a small bead of solder through the hole on the nickel pin with the preheated soldering iron.

Press the outer fitting body over the end of the cable and pin, also pressing tightly against the white dialectric.

Slide the connector parts back up the cable, seating each into the outer connector body. Screw the backing nut into the connector body to complete the termination.
