Best Practices for Routing and Installing Double Shielded Coax Cable

Introduction

Double shielded coax cable is a type of cable used to transmit high-frequency signals, such as those used in video and data applications. It is made up of two layers of shielding, which helps to protect the signal from interference. When routing and installing double shielded coax cable, it is important to follow best practices to ensure that the cable performs properly and to avoid damaging the cable.

Routing

Ensure the cable is routed through non-conductive and non-corrosive materials. This is especially true for the inner shield, as it is more prone to damage.

Avoid sharp bends in the cable, as this can damage the inner shield and cause signal degradation. The minimum bend radius for most double shielded coax cables is 4 inches.

Keep the cable away from sources of heat and moisture, as these can damage the cable.

When running the cable through walls or ceilings, use a conduit to protect it from damage.

Installation

Use the correct connectors for the type of cable being installed. Improperly sized connectors can damage the cable or cause it to fail.

Strip the cable to the correct length, typically 1/2 inch. Stripping the cable too much can expose the inner shield, while stripping it too little can prevent the connector from making a good connection.

When connecting the cable to a connector, use a crimping tool to secure the connection. Do not use pliers, as this can damage the cable.

Test the cable after it is installed to ensure that it is working properly. This can be done using a cable tester or by connecting the cable to a television or other device.

Termination

Use the correct terminators for the type of cable being installed. Incorrectly sized terminators can damage the cable or cause it to fail.

Install the terminators at the end of the cable to prevent signal loss and crosstalk.

Use heat shrink tubing or electrical tape to seal the terminators and protect them from the environment.

Additional Considerations

Use high-quality cable and connectors. This will help to ensure that the cable performs properly and lasts for many years.

Properly ground the cable. This will help to protect it from electrical surges and other hazards.

Inspect the cable regularly for damage. This will help to identify and fix any problems before they cause the cable to fail.

By following these best practices, you can ensure that your double shielded coax cable is routed and installed properly, providing you with years of trouble-free service.
