Do I need a new antenna for Digital TV?
If you are already receiving good quality reception then you probably wont need a new antenna. Old antennas and cabling may need to be replaced if they are producing poor quality signal, however most antenna systems are able to receive Digital reception.
What is the Difference between Analogue and Digital TV antennas?
There is no such thing as a digital antenna. You just need an antenna that receives good quality reception for the required channels in your area.
What do I need to receive Digital TV?
Simply you need a Digital TV Tuner, whether it is a HD Digital settop box connected to an Analogue TV or a TV with a Digital Tuner built in that is connected to a good quality signal from your antenna system.
Why can I get some channels and not others?
New TV stations have been introduced and your TV may require retuning to receive them. If you still don't receive them after retuning, you may have poor TV reception and your TV is unable to decode the signal of those particular channel carriers.
My TV crackles and pops. It has funny squares on the screen. What could be causing that?
If you have channel numbers like 350 or 352 in you channel list then you are receiving "ghost" channels from another transmitter and require a manual tune of your equipment to the channels from you main transmitter to eliminate the ghost channels. If not then you most likely have poor quality reception. Recently introduced 4G transmitters on Blackwall Mountain have been causing what is called "LTE" interference which can be easily fixed by upgrading old amplifiers or installing a filter on some newer models.
Do I need a Booster or Amplifier?
A booster or signal amplifier increases the strength of your signal from your antenna to compensate for loss through cabling. The most common is a masthead amplifier which is located under the antenna. Amplifiers are common on the Central Coast as most of our reception comes from Gosford or Bouddi Transmitters. These towers broadcast at a weaker signal strength than Sydney or Newcastle Transmitters, so often a masthead amplifier is used. HOWEVER amplifiers should be used with caution as too much signal can cause the same problems as not having enough and require being set to a specific strength.
