Attic Box wiring options

Although we supply a FREE eBook when you purchase an Attic Box, we strongly recommend that you get a professional to finalise the installation for you. There's a strong possibility that you will get the signal levels wrong by over-amplifying (or attenuating) and there's a strong possibility that you will get the choice of UHF channels wrong, resulting in severe interference. Please use double-shielded coaxial cable for every connection.

What use is an Attic Box?

An Attic Box is able to combine the SAT LNB, TV AERIAL and RADIO AERIAL signals and send them down a single coaxial cable to your main room. (You will also need a Return Feed back to the Attic Box). This reduces the cable requirement to two instead of four.

You *can* use your existing TV aerial cable as the return feed and simply add the new down feed using double-shielded cable. However, for best results (maximum signal with minimum interference) we recommend you use double-shielded cable for ALL connections.

The diagram above shows a typical Attic Box wiring layout where the Attic Box is expected to be in the roof space or some dry upstairs location. There are optional inputs for an FM aerial, DAB aerial, security camera (or pond camera etc.) A 230 volt AC power supply is required.

The wall plate is in the main viewing room. You can choose from a selection of wall plates, dependent on whether you need the telephone sockets and return feed. The RETURN feed will allow you to distribute the Sky Digibox programme AND normal TV aerial signal to other rooms, as shown. (So it's not really optional - it's essential!) A tvLINK system can be used in each room. The return feed can also carry other signals from the main viewing room (VCR, DVD etc.) These must all be tuned to separate UHF channels 21 - 69 as described in our eBook "Piping TV Around the House".

The diagram below shows how an Attic Box (Main) and an Attic Box (Option) can be used in order to feed an additional L8 rooms. (Note that ALL cable must be proper double-shielded satellite TV coax. Although cheap "TV cable" may be used for those feeds carrying only the RF signals, you risk severe interference problems with it.) See wall plates

The Televes Attic Box should be installed as close to the outside TV aerial as possible and connected directly to it with double-shielded cable. The Attic Box is itself an amplifier, consequently no other amplification is required. The loss in 5 metres of cable (less than 1 dB) will make no significant difference to the end result.

To make ordering easier you can use the buttons below. Be sure to set the quantities to what you need. You can also change the quantities in the shopping cart. Any item set to zero will be deleted. You can also add additional items from the catalogue. See page 15 for wall plates and page 8 for cable.

An Attic Box uses only "F" connectors for its connections.
