The quality of digital TV reception, like analog TV reception, still depends on the quality of your antenna and associated cabling. Poor reception wth digital transmissions can result in no picture being received at all, compared to a ´noisy´ picture with analog TV. You should consult a qualified installer to install a new digital antenna.
Units and apartments
Many apartments and units share a communal master antenna. Many of these would need to be upgraded before individual units can receive digital TV. You should consult your body corporate to upgrade your antenna system to digital.
Digital TV can provide a clearer picture, improved sound, widescreen format and additional benefits such as interactive services.
The switchover will mean you will be unable to receive TV transmissions without the right equipment. The current target for the switchover is 2010-2012.
