Your home is likely to contain an increasingly complex system of telecommunications and home entertainment equipment. Part of these systems will be visible, especially if they have been installed since the house was built, but much of the wiring will be concealed. Here is an overview of the systems, and an explanation of how everything is interconnected.
Communications and home entertainment systems consist of similar components. These include a signal collector or a piece of electrical equipment that generates a signal, and cables of one sort or another to transmit the signal to this receiving equipment that makes the signal visible or audible to the user.
Home Entertainment Systems
In a typical home, the heart of the entertainment system is the television set. The family set is likely to be connected to an aerial socket outlet which is wired to an external all loft TV aerial, while other sets will probably rely on portable aerials. Video or DVD equipment may also be connected to the TV set as an alternative signal source.
Most radio sets in the home are likely to be portable, but in the tuner and home entertainment system may be connected to a separate FM aerial for better reception. The hi-fi system also allows CDs and other audio sources to be accessed. You can easily provide additional TV
and FM aerial socket outlets in the home by extending the aerial system you have already.
Increasing numbers of homes no received TV and FM signals from a satellite dish, which gathers analogue or digital signals broadcast via stationary satellite, or from a local cable network. These incoming signals can be channelled to other TV sets or tuners.
“Fitting a home entertainment system is easy when you know how.”
Working With Coaxial Cable
If you are installing a new aerial downlead, plan the route of the coaxial cable with care. To minimise signal losses, always use good quality screened cable, and keep the route as short as possible. Avoid sharp bends which could kink the cable, and avoid crushing it when driving in cable clips.
Installing Aerial Outlets
Aerial outlets can be flush or surface mounted. A single outlet is shown here. A twin outlet is fed by two separate downleads, usually one from a TV aerial and one from FM aerial. A diplexed outlet has one TV and one FM socket. It is fed by a single aerial downlead and contains electronic circuitry that splits the signal to the two sockets. A Second diplexer is fitted usually in the loft to combine the feeds from the TV and FM aerial.
For satellite or cable services, outlet plates with threaded (f-type) connections are used, allowing the coaxial link to the TV set to be physically secured to the outlet instead of having a push fit connection. Twin Tv outlets are also available with one F-type socket and one coaxial socket.
