Here is the clamp Type-N male connector for LMR400 or Belden 9913 coaxial cables. left to right: male conta...
To assemble the clamp connector onto a cable, start by sliding the heat shrink tubing, the nut, the washer and the gasket over the end of the ...
Make a cut through the outer jacket down to the braided shield all around the cable about 3/8 to 1/2 inch from the end. A single-edge razor blad...
Remove the piece of the jacket, exposing the braided shield.
Rake out the braid. A fine-tooth comb works well for this.
Then, stand the wires up perpendicular to the cable....
....and trim the wires to 3/16". Ordinary scissors work fine.
Temporarily slip the clamp over the trimmed wires. This presses the shield wires back over the jacket. Check that no wires protrude from the r...
Cut through the foil shield and the insulator down to the center conductor, without nicking the center conductor. Make this cut to leave 1/8...
Remove the cut piece of the foil-wrapped insulator. Important: Check to be sure this is a clean cut, with no part of the foil shield able to...
Cut the center conductor to leave 1/8" extending from the insulator.

The tiny soldering hole in the side of the male contact is made for .022" diameter solder.
Soldering the male contact to the center conductor requires a lot of heat. The large copper coated aluminum center conductor wire is a good ...
To solder the male contact, secure the cable in a vice or other holding device with the solder hole facing *up*. Hold the solder vertically into...
After soldering the male contact, assemble the connector by slipping on the clamp and screwing the nut into the connector body.
Wrench flats allow for snug wrench tightening. Tightening the connector compresses the clamp, providing strain relief for the cable, and ...
Slide the heat shrink tubing up onto the connector.
Apply heat all around until the tubing shrinks tightly against the cable and the connector. You now have a functioning connection at the end of ...
