The introduction of Digital Terrestrial Television (DTT) in the UK has presented a considerable challenge to the TV aerial industry. The characteristics of DTT, from a reception viewpoint, are significantly different to analogue TV and this makes it much more difficult to ensure that an aerial installation is satisfactory. In particular, the severity of most analogue reception problems such as marginal signal strength, co-channel interference, overloading of receivers/amplifiers, reflections from buildings, etc. can often be assessed by their effect on picture quality. In contrast, very little information on reception quality can be obtained in the same way for DTT and inappropriate aerials have often been installed.
