2. Why do I need a HD set top box?
3. Do I need to adjust the antenna for the new HD TV?
Suggestion:
1. Covered by link provided by David D.
2. All new panel TV’s in Australia come with integrated digital HD tuner even cheap brands like Sanyo, Rank Arena, AWA and Vivo. Therefore NO HD set top box needed.
3. Indoor antennas are only of any good in strong signal areas. You have to be very close to the TV transmitters. Even so they are still troublesome to use. An appropriate outdoor antenna is always best with any TV.
