Aerial System

In the olden days a dwelling would have just one television located in the lounge or dining room; today it is common to have a television in every room of a dwelling including the bathroom. Each television will have an aerial input for terrestial television signals, many of the televisions will have a satellite receiver box either Freesat or Sky and many of those boxes will have PVRs (personnal video recorders) which require two aerial signals from a satellite dish. Then there are the cable tv boxes which receive signals via television aerial type cable.

To cater for the increasing number of aerial points required in the modern dwelling a specialised aerial distribution system is required. The input to the distribution system is the terrestial digital tv aerial, FM aerial, digital radio aerial and the satellite quattro LNB with four outputs, (horizontal and vertical polarisation each at high and low band). Each television point will require two cables from the amplifier or repeater amplifier as necessary, thus in a house with three bedrooms, two reception rooms and kitchen there will be at least six television points and a 12 output amplifier.

It is a fact of life that rooms will be remodelled at varying intervals it is essential that there are sufficient aerial points suitably located to cater for the various possible postions of the television equipment.

As part of the aerial installation any AV system should be included as part of that system, since where ever AV systems are installed it invariably includes aerial systems. The key to AV systems is to ensure that the cables interconnecting the units of the system are incorporated into the wiring system and are therefore 'hidden'.
