Glossary > Wideband Aerials

Traditionally aerials sold for analogue use are known as grouped aerials, which mean they will only work over a selected range of channels in the available bandwidth. This was very useful when there were only four TV channels as these aerials reduced interference from other transmitters. However, when Channel 5 and Digital transmissions developed there was often not enough space in the in the grouped bandwidths to fit the extra channels in so they had to fit in areas outside the grouped aerials capability and could not therefore be received.

In order to receive the full range of signals wideband aerials are used. As the name suggests wideband aerials are able to receive the full TV bandwidth and are capable of receiving all the analogue and Digital transmissions.
