What Are the Steps to Terminate a Coaxial Cable?

Terminating a coaxial cable correctly is essential for ensuring optimal signal transmission and preventing signal loss. Follow these detailed steps to terminate a coaxial cable effectively.

Gather the Necessary Tools and Materials

Before starting, ensure you have all the necessary tools and materials:

• Coaxial cable
• Coaxial cable stripper
• Compression or crimp connectors
• Compression or crimping tool
• Cable cutter
• Utility knife

Step 1: Cut the Cable to the Desired Length

Using a cable cutter, cut the coaxial cable to the desired length. Ensure the cut is clean and straight to avoid complications during the termination process.

Step 2: Strip the Cable

Use a coaxial cable stripper to remove the outer jacket of the cable. Typically, you will need to strip back about 0.5 inches (12.7 mm) of the outer jacket to expose the braided shield. Be careful not to damage the shield or the underlying dielectric material.

Next, strip about 0.25 inches (6.35 mm) of the dielectric material to expose the inner conductor. Ensure the inner conductor is clean and free of any nicks or cuts.

Step 3: Fold Back the Braided Shield

Gently fold back the braided shield over the outer jacket. This ensures good contact with the connector and helps maintain signal integrity. Make sure the shield is evenly distributed and not bunched up.

Step 4: Attach the Connector

Choose the appropriate connector type for your application (compression or crimp). Slide the connector onto the cable, ensuring the inner conductor goes through the center pin of the connector. The folded-back braided shield should make contact with the connector’s outer body.

For compression connectors:

1. Insert the cable into the connector until the dielectric is flush with the inside of the connector.
2. Use a compression tool to secure the connector. Squeeze the tool handles until the connector is fully compressed and securely attached to the cable.

For crimp connectors:

1. Slide the connector onto the cable and ensure the braided shield is in contact with the connector body.
2. Use a crimping tool to crimp the connector onto the cable. Apply firm pressure to ensure a secure connection.

Step 5: Inspect the Connection

After attaching the connector, inspect the connection to ensure it is secure and properly aligned. The inner conductor should be centered within the connector pin, and the braided shield should have good contact with the connector body.

Step 6: Test the Cable

To verify the termination, use a coaxial cable tester. Connect both ends of the cable to the tester and check for continuity and signal loss. A properly terminated cable will show minimal signal loss and good continuity.

Final Tips

• Ensure you use the correct connector type for your cable (e.g., RG6, RG59).
• Double-check all measurements and cuts before attaching the connector to avoid errors.
• Practice on spare cable pieces if you are new to terminating coaxial cables to gain confidence and precision.

By following these steps, you can achieve a reliable and efficient termination for your coaxial cables, ensuring optimal performance and signal integrity in your network or RF setup.
