You will need an aerial to watch analogue or digital television. For satellite TV you'll need a satellite dish to receive signals. You don't need an aerial for cable TV.
Digital TV
By 2012 the UK will have entirely switched over to digital TV. You'll need a set-top box to view channels as the analogue signal will be turned off entirely. To find out when your area will be affected you can use Digital UK's postcode checker.
You may be eligible for the Switchover Help Scheme if you meet certain criteria. Visit the Digital UK site for further information.
Where to position your aerial
For best results it's a good idea to position your aerial as high up as possible, whether this is inside or outside the house.
External aerials
You don't need to have a 'digital aerial' for switchover, and if you already have good reception it's unlikely that you'll need to replace your aerial.
It's best to install your TV aerial as high up as possible on the outside of your home. If you can't position it on the roofline then the antenna should at least be on the side of your building facing the transmitter.
Make sure that your aerial is positioned away from any other aerials and pointing directly at the transmitter. This is usually in the same direction as the aerials on neighbouring houses.
Internal aerials
If it's not possible to install an external aerial, for example if you live in a conservation area or listed building, then you may be able to get good reception with an indoor aerial situated in the loft or a set-top aerial.
Bear in mind that some set-top aerials are unsuitable for digital TV and may need to be replaced.
Splitters
If you want to run more than one TV on your aerial then you'll need a splitter. These are usually "T" or "Y" shaped and made of metal and plastic. You plug your TV aerial into one end then connect your TV fly leads into the other sockets. This will allow you to feed multiple TV sets or a TV and a recorder with one aerial.
Boosters
If the signal from your aerial is not strong enough then a signal booster could help performance. These can be bought from most retailers with an electronics section.
If you rent your property then check your tenancy agreement, or contact your landlord or letting agency, to determine who is responsible for the installation or repair of an aerial.
