Most aerials should work after digital switchover, but a few may require replacement or new cable connections, particularly if you decide to get Freeview.

The tests featured in the 'Reception Prediction' download on this page can be used as a guide to help you decide if you should get your aerial checked by an installer.

The booklet explains the teletext test which is being transmitted on all four analogue channels to help you determine whether your aerial system is likely to be good enough to receive digital television after switchover.

• The test does not help you assess whether your aerial is good enough to receive Freeview today.
• Visit teletext page 284 to carry out the aerial test.
• It can be found on BBC One, BBC Two, ITV1, Channel 4 and S4C.
• A Welsh-language version is available on S4C page 484.

The test is a guide to the likelihood of digital reception using your existing aerial.

If you need a more definitive answer then you may wish to seek advice from a good aerial installer or retailer.
