One of our customers, Barry, has kindly provided the diagram below.

You can see that Barry has connected the LNB satellite signal, the TV aerial UHF signal and the radio FM aerial to his Loft Box. This combines the three signals and sends them to the living room wall plate which separates them.

The LNB satellite signal is connected directly to the Sky Digibox.

The UHF TV signal goes through the Video Recorder and out to the Sky Digibox aerial input.

(To record from Sky use a Scart lead).

The Digibox RF output goes to the TV set but for best pictures and audio use a Scart lead.

The Digibox RF2 output feeds the combined Aerial signal and selected Sky program (and VCR output) up the return feed to the Loft Box.

The Loft Box sends this combined signal out to the bedroom TV sets (with the FM radio signal as well, if present).

Barry chose UHF channel 34 for his VCR output and UHF channel 69 for the Sky Digibox RF outputs. These are clear of his existing analogue TV and Freeview transmissions.

There are lots of ways that you can use a Loft Box so this is just an example. You might want to add a Freeview box in which case you would connect it directly to the TV socket of a wall plate. In the living room it goes between the wall socket and the VCR aerial input. In the bedroom it goes between the wall socket and the TV set.

Barry also fitted a Remote Extender in each bedroom. With a Loft Box system, it's easy. You simply connect it between the wall socket and the TV. (Or between the wall socket and your Freeview box, if you use one).

It's important that you wire up the loft box FULLY as shown in our web page wiring diagram. If you omit vital connections (such as the return feed) the unit can not work. This is obvious from the internal diagram on page 26 of our "Piping TV.." eBook.

Without the Return Feed the signals go ONLY to the living room. They can not go to TV OUT 1 - 4 because there is no internal connection.

Please DO connect the Return Feed. It need only be a short link cable for the purpose of testing. Please also be sure to connect the decombiner wall plate for each output in use, otherwise you could cause damage.

IMPORTANT

You should be aware that mains-powered equipment installed in the loft can be a fire hazard which may affect your insurance! A loft can become very hot in summer, which adds to the risk. If you install equipment in the loft, please take all appropriate steps to ensure that a fire can not spread, including:

  • Install it in a flame-resistant container with good ventilation.
  • Keep it away from flammable materials.
  • Ensure that it can't accidentally be covered by blankets etc. tossed hurriedly into the loft.
  • Ensure that it is properly fused and connected through a Residual Current Breaker or other safety device.
  • Ensure that it is correctly earthed if an earth connection is provided.
