the DTV signals to the television. Reliable digital TV reception requires high quality, robust DTV
signals which can only be achieved when using a TV antenna and cabling designed for digital
TV reception.

For your safety, the antenna and cabling should be inspected / installed by a licenced installer
that should comply with Australian Standard AS1417.1 for Domestic installations or AS1367
for MATV installations.

●
Hint: Some degradation of the DTV signal may occur if you
are connecting the aerial through an external device (e.g.
DVD Recorder or Set Top Box). In this case it is better to
use a splitter and connect the aerial directly to both devices.
●
Check to ensure your area is covered by DTV
transmissions.
●
Check that the aerial and antenna cable are designed
for DTV reception. If you live within 5-10 Km of DTV
transmission towers, a combined VHF / UHF Digital TV
aerial should be adequate. Outside this area, separate VHF
and UHF aerials provide superior reception performance.
●
If you live in a unit or apartment, check to ensure the Master
Antenna TV (MATV) system is designed for analogue and
DTV reception. Please consult your body corporate.
