Product Information

Full details

The Dencon Double Flush Aerial Socket (UK) - ST3050 is designed for homeowners and installers needing a reliable way to connect multiple TV aerial points from a single cable run. Its key benefit is providing two distinct outputs from one input, simplifying installations in multi-room setups. A potential caveat is its UK-specific design, requiring appropriate coaxial connectors.

FAQs

What type of coaxial connector does this socket use?

The Dencon ST3050 is designed for standard UK coaxial cable connections, typically using F-type connectors for the input and potentially Belling-Lee (coaxial push-fit) or F-type for the outputs, depending on the specific configuration required for your devices.

Can I use this for satellite TV signals?

This socket is primarily designed for terrestrial television aerial signals (Freeview). While some coaxial components might be compatible, it is not specifically designed or recommended for satellite TV (e.g., Sky, Freesat) which uses different frequency bands and connector types.

Do I need a special back box for this socket?

Yes, for a flush-mounted installation, you will typically need a standard UK single-gang electrical back box, which is recessed into the wall.

How do I connect the cables?

The incoming aerial cable connects to the main input terminal. Then, separate cables run from the two output terminals to each of your TVs or devices. Ensure all connections are secure.

Does this socket attenuate the signal?

All splitters and sockets introduce some signal loss (attenuation). The ST3050 is designed to minimize this loss for typical domestic installations. For very long cable runs or weak aerial signals, signal amplification might still be necessary.

What is the warranty period for this product?

Please refer to the retailer or manufacturer's documentation for the specific warranty period, as this can vary.

Troubleshooting

No signal on one or both outputs

Check that the incoming coaxial cable is securely connected to the input terminal. Ensure that the cables to each output device are properly terminated and connected. Verify that the aerial itself is functioning correctly and has a clear line of sight. Test each output individually by connecting directly to the input if possible.

Poor signal quality or interference

Ensure all coaxial cable connections are tight and free from damage. Check for kinks or excessive bending in the coaxial cables. If using screw-on connectors, ensure they are properly fitted. Consider using a signal amplifier if the cable run is very long or the aerial signal is weak.

Socket is loose in the wall

Verify that the socket is securely fastened to the correct size back box. Ensure the back box itself is firmly installed in the wall. Tighten the screws that secure the socket faceplate to the back box.

Setup, Compatibility & Care

Setup:

  1. Ensure the main coaxial cable from the aerial is run to the location of the socket.
  2. Isolate and prepare the end of the coaxial cable for connection.
  3. The ST3050 typically requires a standard UK single-gang electrical back box for flush mounting.
  4. Connect the incoming coaxial cable to the primary input terminal on the rear of the socket.
  5. Connect individual coaxial cables from each output terminal to the respective TV or device.
  6. Secure the socket faceplate to the back box.

Compatibility:

  • Compatible with standard UK television aerial systems.
  • Requires standard UK coaxial cable and F-type or Belling-Lee connectors as appropriate for your cable type.

Care:

  • Clean with a soft, dry cloth. Avoid abrasive cleaners or solvents.
  • Ensure connections remain secure to maintain signal integrity.
