Hey there, DIY enthusiasts and curious minds! Ever heard that splicing a coaxial cable is a tough nut to crack? Well, I’m here to bust that myth. Splicing coax cable is surprisingly easy, and you don’t need to be a tech genius to do it!

First things first, you’ll need some basic tools to splice a coaxial cable. Don’t worry, these aren’t anything fancy or hard to find. In fact, the process is so straightforward that even kids can learn to splice a coaxial cable and repair it like a pro.

Depending on the type of cable you’re dealing with, you might need some specialized tools. The good news? These are easily available at any local hardware store.

If you’re on the hunt for a reliable coaxial cable to connect your TV to the antenna, here’s a recommendation for you. Try out this 12ft long RG6 Coax TV Cable. It’s known for its excellent quality and reliability, making it a great choice for your setup.

Now that you know splicing coaxial cable is not a Herculean task, let’s dive into the how-tos. Stay tuned as we unravel the steps to make you a coax cable splicing expert in no time!

Few Things Need to Look After Before Starting Splicing

Before you jump into the world of splicing coaxial cables, there are a few key things you need to check off your list. Trust me, a little prep work goes a long way!

1. Know Your Cable:

Identifying the cable type is crucial. Common types like RG6 and RG59 are often marked on the cable itself. If you can’t find or read the marking, no worries! Just take a piece of it to your local hardware store. They’ll help you figure out what you’re working with.

2. Decide on Your Approach:

Ask yourself: Do I need connectors? Am I extending or shortening the cable? Your answers will guide your next steps and help you gather the right tools for the job.

Gathering Your Toolkit:

Here’s what you’ll need for splicing a coaxial cable:

  • Two F connectors
  • Barrel connectors
  • Diagonal pliers
  • A coaxial cable stripper (preferably, but a knife can work in a pinch)
  • A coaxial crimping tool (for those F connectors)

Now that you’ve got your tools and know your cable, you’re all set to learn both connector and non-connector splicing methods.

How to Splice Coaxial Cable Using Connectors

Before diving into splicing, it’s crucial to have the right tools. A coaxial cable stripper is a must-have for this job. Remember, there are different types of coaxial cables, so ensure your stripper is compatible with the cable you’re working on.

Step 1: Put Cable’s Terminated End into the Stripper

  • First, take one end of the cable that’s been terminated (or cut off).
  • Now, insert this end into your coaxial cable stripper. Here’s a crucial part: make sure the end of the cable lines up with the guide mark on your stripper tool.
  • Why is this important? It helps ensure that, once spliced, the coaxial cable is of equal length and properly aligned. This step is key for a successful splice.

Step 2: Fold the Wire Mesh

  • Once you’ve stripped the cable, you’ll notice the insulation and a wire mesh covering it. At the tip, a small part of the copper cable will stick out, resembling a male connector.
  • Here’s a vital step: fold the wire mesh back onto the outside casing. Why? Because you won’t be using this wire mesh anymore.
  • Be extra careful to ensure no stray wires are left out. Stray wires can mess with the signal strength and quality of your cable. So, double-check to make sure everything is neat and tidy.

Step 3: Put the Cable into Compression Connectors

  • Now, it’s time to attach the coaxial compression connectors. Carefully slide them onto the cable end without damaging the protruding copper wire.
  • Repeat the same process with the other end of the coax cable.
  • Hold the cable with the compression connector firmly in place. This ensures the connector is properly crimped to the wire.
  • Remember, consistency is key. Do the same with the other end of the coaxial cable to ensure a balanced and effective splice.

Step 4: Insert the Cables into Barrel Connectors

  • Now that you have prepared both ends of the coaxial cable with compression connectors, it’s time to bring them together.
  • Take each cable and insert it into the barrel connector. Here’s the key: make sure that the protruding copper wire from each cable enters the female connection parts. These parts are located on both sides of the barrel connector.
  • Carefully but firmly, tighten the collar of each cable connector onto the barrel connector. This action secures the cables in place and ensures a strong connection.
  • Double-check to make sure everything is tight and secure. A loose connection can lead to poor signal quality or disconnection.

How to Splice Coaxial Cable Without Connectors

Ever wondered if you can splice a coax cable without fancy connectors or a commercial splice kit? Well, you definitely can! It’s a handy skill, especially if you’re in a pinch and don’t have access to specialized tools. Let’s dive into how you can splice your coaxial cable using just a sharp knife and a soldering iron.

Step 1: Stripping the Cable

  • First things first, grab your knife. Carefully strip off the outer jacket or rubber shield of the coaxial cable for about a couple of inches.
  • Then, gently push the wire mesh back as far away from the severed ends as possible.

Step 2: Exposing the Copper Wire

  • Your next task is to cut just a bit of the insulation at the tips. This will expose the copper wire, which is the central conductor of your cable.

Step 3: Prepping for Soldering

  • Now, before you get to the soldering part, wrap some electrical tape around the area you’re going to solder. This helps insulate the solder joint.

Step 4: Joining the Wires

  • Time to get the wire meshes from both ends of the cable close to each other. This step is crucial for a good connection.

Step 5: Securing the Joint

  • Finally, cover the entire joint with electrical tape. This not only improves conductivity but also waterproofs your splice.


And there you have it! You’re now equipped with the know-how to splice a coaxial cable, both with and without connectors. Feeling like a pro yet? You should be!
