Installation Tips for Double Shielded Coax Cables
Double shielded coax cables (DSCC) provide superior signal protection and electromagnetic interference (EMI) resistance compared to standard coaxial cables. They are commonly used in high-frequency applications, including satellite TV, broadband internet, and networking. Installing DSCC requires specific considerations to ensure optimal performance and longevity. Here are comprehensive installation tips to guide you through the process:
Cable Selection and Handling
Choose high-quality DSCC: Opt for cables with a thick, durable outer jacket and a solid copper core to minimize signal loss and maintain integrity.
Handle with care: Protect the cable from kinks, bends, or scratches during handling and installation, as these can compromise its performance.
Connector Preparation
Use appropriate connectors: Select connectors specifically designed for DSCC, ensuring a secure and low-resistance connection.
Strip the cable carefully: Remove the outer jacket and braid shielding to expose the inner conductor, being careful not to cut the shield or core.
Attach the connector: Slide the connector onto the cable and crimp it firmly using a crimping tool. Ensure a snug fit to prevent signal leakage.
Cable Routing
Avoid sharp bends: Maintain a minimum bend radius to prevent kinking the cable, which can cause signal degradation.
Keep away from noise sources: Route the cable away from electrical devices, transformers, and fluorescent lights, as they can generate EMI.
Ground the shield: Connect the shield to a grounding point to dissipate electrical noise and improve signal quality.
Environmental Considerations
Protect from moisture: Exposure to moisture can damage the cable and connectors. Use waterproof enclosures or sealing tape to provide protection.
Manage temperature extremes: DSCC cables can be affected by extreme heat or cold. Ensure they are installed in an environment with controlled temperature.
Testing and Maintenance
Test signal integrity: Use a cable tester to verify the continuity and signal quality of the installed cable.
Inspect regularly: Periodically inspect the cable for any signs of damage, deterioration, or corrosion.
Replace if necessary: If the cable shows signs of significant damage or deterioration, replace it to ensure reliable performance.
By adhering to these installation tips, you can ensure that your double shielded coax cable installation provides optimal signal quality, reduces EMI interference, and provides long-term reliability.
