Summary

Question – Do I need a new aerial?

Answer:


Viewers thinking about purchasing a new piece of equipment capable of receiving the new digital television or radio programmes should now always consider how they intend to receive their digital signals – You may need a new aerial!

It’s a well known fact that the majority of households across the country are currently receiving their television signals through an analogue aerial that is more than 10 years old.
After ten years of ware and tear caused by exposure to the elements, viewers should seriously consider upgrading their existing aerial system to receive and distribute the new digital broadcasts around their home.

Unlike the old days when you used to be able to receive analogue broadcasts in some parts
of the country using a piece of ‘wet string’, the new digital system relies on your equipment receiving a clean uninterrupted stream of digital data which it decodes from the transmitted digital signal (A Digital Multiplex).

Unfortunately due to the amount of spurious radio waves now being broadcast by various pieces of electrical and electronic equipment around your home, even the new digital signals can some times be afflicted by one or two minor irritations.

Just as with the old analogue services, digital television can occasionally display unusual affects, which impair our overall viewing pleasure. The only difference is that these symptoms take a very different appearance to the effects that we have seen before on analogue televisions.

Example: Instead of an analogue picture becoming grainy (snowy) due to the effects of limited reception caused by something like bad weather, a digital picture may ‘Freeze’ or disappear completely, leaving you with just a ‘Red Dot’ or a warning like ‘No Signal’ on the TV screen.

Alternatively where analogue pictures used to show black and white dot patterns caused by local electrical interference, pictures produced from a digital signal may intermittently ‘Break up’ or create a Mosaic affects (Macro Blocking).

"Digital aerial installations should incorporate high quality materials, which have been approved for digital reception and completed by professional installers using the latest digital Test equipment."

Question: Can I receive all the Freeview services where I live?

Answer:

Freeview signal reception is governed by the availability of digital services in your particular area and is usually dependent upon where you live in relation to the digital transmitters covering your area.

Key factors affecting your signal reception include the performance of your TV aerial (Is it suitable for digital reception), your geographic location/ orientation to the digital TV transmitter and an unobstructed clear line of site between the aerial and the transmitter
(Example - No large hills, trees or tall buildings blocking the incoming signal to your aerial)

Viewers situated in main transmitter coverage areas will normally receive a greater number of digital television services including Public Service Broadcasts (PSB’s) and a range of Commercial services like ITV2, ITV4, Virgin, E4, SKY News etc.

Note: Viewers being supported by local relay transmitters should in theory receive a selection of digital broadcasts including the Public Service Broadcasts (PSB’s) such as BBC1, BBC2, ITV etc.(The number of received services/ MUX’s is dependent upon local coverage)

Question: Can I receive Freeview HD services where I live?

Answer:


Viewers currently receiving normal Freeview (SD) services may not be able to receive the new Freeview HD services as the HD service coverage is different in most cases to that of the existing Freeview SD services.

Freeview HD (T2) signal reception is governed by the availability of services in your particular area and is usually dependent upon where you live in relation to the digital transmitters covering your area. (Note: Not all digital TV transmitters will be broadcasting Freeview HD services)

Note: Viewers situated in some main transmitter coverage areas may be able to receive the new Freeview HD services using a new Freeview HD receiver (T2 type STB/ IDTV); however we have noticed that in some cases initial HD services are being transmitted at a lower signal level to the existing SD services. (You may need a more require a larger high gain aerial to receive the new Freeview HD services in your local area (Service Availability is dependent upon coverage)

It is always recommended that viewers undertake a Digital UK postcode check to ascertain what digital services they may/ should receive – www.digitaluk.co.uk
