Coaxial cables are used for signal transmission in television, computer and audio broadcasting networks. Many other communication systems also use coaxial cables to carry high frequency signals. If your project uses coaxial cables, knowing how to crimp them yourself can save you a lot of money.

Steps

1. 1 Gather the necessary tools and materials. To crimp a coaxial cable, you will need the following:
   • Coaxial Cable Connector (Jack) - There are many variations on this part. Compression connectors provide better contact and look good.The second place is deservedly taken by crimp connectors. Avoid slip-on and threaded connectors.
   • Crimping tool (crimper) - make sure the tool is designed for this type of connector.
   • Coaxial cable stripper (stripper)
   • Nippers or cable cutter
   • Threading Tool - Used to securely insert the cable into the connector.
2. 2 Cut the end of the cable straight. Using a cable cutter, universal crimper, or wire cutters, make the end of the cable where you will install the connector straight. Use your fingers to restore the circular cross-section of the cable.
3. 3 Adjust the stripper to the size of the cable. Most strippers can strip cables with double or multi-layer shielding. Adjustment is made with a hex wrench. If the stripper is not adjusted correctly, the outer casing will be damaged.
   • The most common coaxial cable is RG-6, with a shield of two or more layers. Make sure the stripper blades are set to strip RG-6 and not twisted pair for example.
   • If the stripper is configured to strip a double-layer shield and you are trying to strip a multi-layer shield, the stripping will not perform well.
4. 4 Strip the end of the cable. Insert the cable into the stripper, the end must not protrude beyond the stripper. Clamp the cable in the tool, and twist the stripper two or three times around the cable.
   • Cutting the insulation is complete as soon as you feel no resistance as you turn the tool.
   • Pull out the cable by opening the tool.
5. 5 Remove the outer insulation. There should be two notches on the cable. Remove the outermost segment, the central vein will be exposed.
6. 6 Remove the second segment. The screen and braid will be exposed.
7. 7 A properly stripped cable should look like the illustration - braid, insulation, center conductor. Remove the foil, wrap the cable sheath back away from the dielectric over the outer insulation. Nothing should remain on top of the white dielectric.
8. 8 Trim the center core (if necessary). Most strippers cut the center strand to the desired length, but it is a good idea to check and trim it as needed. The length of the center strand after stripping should be 3.9 mm.
9. 9 Slide the connector onto the cable. Use a threading tool to ensure proper contact. The end of the connector should fit snugly against the edge of the insulation.
   • Be careful not to bend the end of the cable when installing the connector.
   • To securely install the cable into the connector, it can be screwed in with a twisting motion.
10. 10 Crimp the connector with a crimper or press in with a compression tool. The crimping method depends on the type of connector and tool, but is quite simple and intuitive. Crimpers are designed to fit crimp connectors, the compression tool presses the compression connector body parts into each other.
    • Apply enough force to the tool. Crimping or pressing should be done in a single motion, although some tools can damage the cable with excessive force.
11. 11 Check the quality of the crimp. After crimping, the connector should sit firmly on the cable, there should be no protruding wires. Otherwise, the signal strength may suffer.

Tips

• There are many types of coaxial cable. Such as: ADC DSX-CM-1000, WECO Type 734A, Belden YR23922, Belden 1505A and GEPCO VPM2000. The most common connectors are BNC-734 and TNC-734.
• The shielding foil is under the braid and can be trimmed or torn off.
• Any other type of cable will require separate adjustment of the stripper. Use one brand of cable throughout the entire project.
