Product Information

Full details

This 25-meter black twin coaxial cable from Loops is designed for users needing reliable, long-distance signal transmission for satellite TV systems, including Sky Plus/HD and Freesat. Its foam-filled, pure copper construction ensures excellent signal quality and strength, but a potential caveat is that longer lengths may not be supplied on a reel, requiring careful uncoiling. Key features include its robust build, suitability for indoor/outdoor use, and straightforward termination with F connectors.

FAQs

What is the impedance of this cable?

The cable has a standard impedance of 75 ohms, which is suitable for satellite and terrestrial TV applications.

Can I use this cable for Freeview or terrestrial TV?

While primarily designed for satellite, this 75-ohm coaxial cable can also be used for terrestrial Freeview if your aerial and receiver setup requires this type of connection and impedance. However, for standard aerial installations, 300-ohm twin-lead or standard 75-ohm coaxial cables might be more common.

What does 'foam-filled' mean for the cable?

The foam-filled core provides enhanced dielectric insulation, which helps to reduce signal loss over long distances and improves the cable's ability to resist interference compared to solid polyethylene cores.

How do I ensure a weatherproof connection outdoors?

When connecting outdoors, use weatherproof F connectors and consider applying self-amalgamating tape or a weatherproof boot over the connection point to protect it from moisture and UV damage.

What is the velocity factor (VF) of this cable?

The velocity factor of this cable is 0.83, which indicates the speed of signal propagation relative to the speed of light in a vacuum.

Can I cut this cable to a custom length?

Yes, you can cut the cable to any desired length. Ensure you use appropriate F connectors to terminate the cut ends for a secure connection.

Is this cable suitable for underground burial?

While the cable is designed for outdoor use, direct burial without additional protective conduit is not recommended. For underground runs, it's best to use a cable specifically rated for burial or protect this cable within a conduit.

Troubleshooting

No signal or weak signal on receiver

Check that both ends of the coaxial cable are securely connected to the LNB and the receiver. Inspect the F connectors for a solid connection and ensure no stray wires are bridging the center conductor. Verify that the cable is not damaged or kinked along its length. Ensure the correct input is selected on the receiver.

Intermittent signal loss or pixelation

This could be due to a poor connection or damage to the cable. Re-terminate the F connectors on both ends, ensuring a clean and secure fit. Check the cable for any visible signs of damage, especially where it is exposed to the elements. If the problem persists, consider replacing the cable.

Difficulty attaching F connector

Ensure you are using the correct size F connector for 75-ohm coaxial cable. Carefully strip the cable as per the instructions, ensuring the earth braid is folded back neatly and the center conductor is straight and free of nicks. Do not overtighten the connector if it is a screw-on type.

Pros and Cons

Pros

  • Excellent signal quality due to pure copper conductors.
  • Durable and weather-resistant for outdoor installations.
  • Suitable for long cable runs without significant signal degradation.
  • Simple to install and connect with F connectors.

Cons

  • May not be supplied on a reel for 25m and 50m lengths, requiring careful handling.
  • Requires separate F connectors for termination.
  • Twin cable design limits use to specific dual-connection setups.

Setup, Compatibility & Care

Setup:

  1. Prepare the Cable: Carefully strip the outer PVC jacket of the cable to expose the braided earth shield and the inner conductors. Ensure not to cut into the braided shield.
  2. Arrange the Earth: Fold the braided earth shield back over the outer jacket.
  3. Prepare Inner Conductors: Strip the insulation from the two inner conductors, ensuring they are clean and free of stray strands.
  4. Terminate with F Connector: Insert the prepared cable end into an F connector. The earth braid should be secured between the connector body and the outer jacket, and the inner conductor should protrude slightly from the connector's center pin receptacle. Crimp or screw the connector securely onto the cable.
  5. Repeat: Terminate the other end of the cable as required for your satellite dish LNB and receiver.

Compatibility:

  • Receivers: Compatible with Sky Plus/HD boxes, Freesat boxes, and other satellite receivers that utilize F-type connectors.
  • LNBs: Suitable for use with standard satellite dish LNBs.
  • Connectors: Designed for use with standard F-type coaxial connectors (ensure correct size for 75-ohm cable).

Care:

  • Cleaning: Clean the exterior of the cable with a dry or slightly damp cloth as needed. Avoid abrasive cleaners.
  • Protection: Ensure connections are weatherproofed, especially for outdoor installations, using appropriate sealant or weatherproof boots to prevent moisture ingress.
  • Avoid Kinks: Do not excessively bend or kink the cable, as this can damage the internal conductors and shielding, affecting signal quality.
