 How to end a coaxial cable

How to terminate coaxial cable? Coaxial cable can be used to transmit a variety of signals including cable TV Internet and low-quality audio. 

If you are working on a project that falls into one of these categories you can create your cables and save money by learning how to finish the coaxial cable yourself.


Step 1

Collect your materials.

To finish a coaxial cable you will need the following tools and materials:

Coax Compression Connector - There are several types of connectors. Compression connectors provide the best connection and finish to your cable. 

The second best type of connector is Crimp connectors. Avoid push or twist fasteners.

Compression / Shrink Tool - Make sure it is compatible with the compression/shrink connector.

- Cable stripper cable

- Cable cutters

Connector Installation Tool - This tool is used to push the connector firmly into the abstract cable.


Step 2

Cut straight at the end of the cable.

Use your cutting tool to cut straight at the end of the cable. After cutting use your fingers to form the end of the cable back into a circle.


Step 3

Tune your stripper to work with your cable.

Most coaxial strippers can be adjusted to strip double or square coaxial cables. Use the included wrench to adjust the stripper. 

If you do not adjust the stripper properly you may strip the ground wire and damage the cable.

The most common cable is RG-6 square or double. Make sure that the stripper is set for an RG-6 coaxial cable, not another cable size such as an Ethernet cable.

If your stripper is set to double shields but you are trying to strip a square cable not all shielding will be removed.


Step 4

Strip the end of the vacuum cable.

Place the end of the vacuum cleaner cable into the stripper so that the end of the cable is near the far end of the stripper. Clamp the stripper down on the cable and wrap it around the cable two to three times.

You can know when to remove the stripper when you no longer feel resistance when turning.

Do not take off the stripper when you are done. Release it and open it to remove the cable.


Step 5

Pull the outer shield.

After stripping the cable you should see two sections of section. Pull the outermost section of the cable. This should expose the central conductor wire.


Step 6

Pull the second section.

This will expose the foil that insulates the cable. Find the end of the foil and peel it off the cable. It should leave one layer of foil around the white insulation.


Step 7

Fold back the braid.

When you take off the cable jacket you will see a lot of loose ground wires. Fold them back into the cable so that the connector touches all the wires during installation. None of the wires should block the white insulation.


Step 8

Cut the lead wire if necessary.

Most cable stripping tools will leave the correct conductive wire length exposed but it is not harmful to check again before proceeding. The length of the exposed connector cable should be 3.9 mm (.156 inches long.


Step 9

Place the connector on the abstract end of the cable.

Use a push tool to firmly push the connector into the cable until the white insulation burns with the connector.

Be sure to avoid bending the exposed lead wire when installing the connector.

You may need to twist the cable while pressing the tool to connect it securely.


Step 10

Compressor press the connector.

The process of compression or contraction of the connector varies depending on the type of connector you are using. 

Some require you to press down on the cable end of the connector piece while others require you to push the front and end of the connector piece together.

Squeeze the compression or cutting tool firmly. Most tools will not allow you to compress too much but some may damage the cable and connector if they compress too much.


Step 11

Check the connection for defects.

Once you have finished compressing the connector check for loose wires or loose connections. These can lead to a bad signal or a malfunctioning cable.
