How to Splice Coaxial Cable – The Comprehensive Guide

Splicing a coaxial cable is a straightforward task that can be accomplished with ease, given the right tools and guidance. This comprehensive guide aims to provide you with the necessary knowledge and steps to splice your coaxial cable, potentially saving you the cost of purchasing a new one.

Before you begin, it’s important to understand a few key points about the coaxial cable you’re working with. Firstly, identify the type of coax cable you’re using. The most common types for residential use are RG6 and RG59. Secondly, decide whether you want to use connectors for the splicing process. It’s perfectly fine if you choose not to. Lastly, determine if you’ll be extending or shortening the cable.

Once you’ve answered these questions, you can gather the necessary tools for the task.

  • A typical coax splice kit includes a coax cable stripper
  • Coax compression connectors (if you’re using connectors)
  • Coax compression tool (also only necessary if using connectors)
  • Additional coax cable (if you’re extending the cable)
  • A barrel connector or splice adapter
  • And a knife and soldering iron (for those not using connectors).

The process of splicing a coaxial cable can be divided into two scenarios: splicing with connectors and splicing without connectors.

Splicing Coaxial Cable Using Connectors:

  1. Strip the Cable: Use the coax cable stripper to strip your cable. Ensure the stripper is compatible with your coax cable. After stripping, you’ll see the insulation and wire mesh of your cable, with a small part of the copper cable protruding at the tip. Fold the wire mesh back into the casing, ensuring no stray wires are left, as these can interfere with signal quality.
  2. Attach the Connectors: Place the coax compression connectors onto the insulated part of the coax cable, ensuring the copper wire is still protruding from the connector. Repeat this step with the other end of the cable.
  3. Use the Compression Tool: Insert the coax cable (with the connector) into the compression tool and press until the connector crimps to the wire. Repeat this step for the other end of the cable.
  4. Use the Barrel Connector: Insert each cable into the barrel connector, ensuring the protruding copper wire goes into the connection ports on both sides. Tighten the collar of the cable connector onto the barrel connector to complete the splicing process.

Splicing Coaxial Cable Without Connectors:

  1. Strip the Cable: Use a knife to strip off the rubber shield of the coax cable. Push the wire mesh as far back as possible.
  2. Expose the Copper Wire: Cut a bit of the insulator at the tips to expose the copper wire. This allows the wire to overlap when connected.
  3. Solder the Wires: Solder the copper wires together and cover the solder with electrical tape for additional insulation.
  4. Pull Back the Wire Mesh: Pull back the wire mesh towards the tip from both sides.
  5. Solder the Wire Mesh: Solder the wire mesh together.
  6. Cover the Joint: Cover the entire soldered joint with electrical tape for better conductivity and waterproofing.

Now that you’ve learned how to splice a coaxial cable with and without connectors, you’re ready to tackle this task yourself. If you’re looking to get multiple connections from a single coax cable resource, consider using a top-rated cable splitter for an effortless solution.
