As you know coaxial cable which also referred to coax is meant for watching cable TV connections and using computer networks. Such type of wire is noise sensitive which passes the electrical signal through it. Initially, people use a single coax cable for their cable connection requirement. But, as the time progresses, you install more devices like TVs, computers, etc. in different rooms and so you need to extend the coaxial connection through a cable splitter.

Also, when you change the location of the cable TV or any other coaxial device, then also you need to get a coaxial cable extension. Today, I will explain how you can easily splice the coaxial cable for the extended connection requirements.

How to Extend Coaxial Cable

Method-1: Using the coaxial extender

If you need to extend the length of the coaxial cable, then first, gather the required things, like:

  • Two coaxial cables (you can get more as per your needs)
  • A coaxial cable extender/splitter
  • Pliers
  • Other needed things depending on your setup

Now, follow the steps below to make the coaxial cable extension.

Step-1: Disconnect all the connections

The essential step is to protect yourself and the setup from any accidental damage. For this, power off all the devices in the network and unplug them. If you do not take proper care of such important things, then you may end up with a big problem with the electrical hazards. So, take safety precautions first and then move to the next step.

Step-2: Prepare the coax

Now, plug the first coaxial cable into the wall outlet from where the connection is coming. Tighten that end of the cable to make firm contact. You can do this by twisting the wire by your fingers or using the pliers.

Step-3: Use the extender

Connect the other end of the cable to the coaxial cable extender. Now, take the second coaxial cable and plug its one end into the other side of the coax extender.

Step-4: Connect the destination

Now, plug in the other end of the second coax wire into the device in which you want to watch the multimedia contents.

Step-5: Repeat the process
Repeat the process

If you want to extend the length of the connection further, then you can use multiple coaxial extenders and cables.

Method-2: Splicing coaxial cables

If you do not wish to use the cable splitters extenders, then you can bond the two coaxial cables to extend the connection. This process is relatively longer than the previous method, but you can give it a go.

Things you will need;

  • Two coaxial cables (Depending on the needs, you can get more)
  • 90-degree adapter
  • Coax stripping tool
  • Crimping tool
  • Compression connector
  • Grounding block, clamps, grounding wires

Now, follow the steps below to connect two coax cables together.

  1. Unwind the role of the coaxial cables as we do not need any twisted part for making the setup.
  2. Avoid the sharp bends of the cable, and if you can’t avoid it, use the 90-degree adapter to prevent the damage to the wire.
  3. Now, With the help of a coaxial cable stripping tool, strip the cable and leave the foil as it is. Make sure that no any braid wires (stingers) should touch the center conductor. Leave the conductor a little bit longer.
  4. Now, with the help of a crimping tool, connect the opened up end of the cable to the compression connector. You can also use the female to female coaxial adapter to connect the ends of the two coax cables.
  5. With the help of the grounding block, grounding wires, and clamps, bond the coaxial cables to keep the electrical conductivity and continuity.
  6. Now, using the other hardware and material, complete the setup and enjoy the extended coaxial cable connection.
