All,
Analog TV switchoffs are;
All of WA outside Perth (WAW(GWN) & WOW(WIN)) between 1st July - 31st December 2013
Mandurah and Pinjarra are included in this strand. Recommended antenna V5
When commercial DTV starts, your new digital antenna should not be able to not receive ABC1 analog in Bunbury (Mt Lennard out of Bunbury), Great Southern (Mt Barker), Central Agricultural (Mawson), Leeman, additionally you should not be able to receive GWN Mt Lennard, Mt Barker, Kambalda.
Follow the sequence below to determine what you need to do. This applies to new and existing installations, in which pixellates (picture breaks up into blocks) and the sound chirps)
Antenna Selection
1.
Determine the most appropriate transmitter site
Most regions have a main transmitter shown in
bold and some translators. Translator is of lower power than the main transmitter for the region. Translators are used to fill in a shadow area caused by the local terrain. A translator converts the signal from one channel to another to prevent interference.

Open on another screen
Coverage area maps and select the state and your DTV transmitter. If present this will give you a coverage area map to determine which site is best for you.
If an antenna technician can provide evidence that there are no signals at your site, you can get the ABC, SBS, two commercial stations and some radio channels directly from a satellite. Go to the end of this post.

“Antenna Replace”
Red background, white print.
Digital TV will never use channels 0 – 5A. This is due to the problem of impulse noise from electrical switching and arcing. You can minimise this problem if you antenna is not designed for these channels. Channel 0 – 5A antennas are very wide and are more liable to get bird and wind damage as well.
The best antenna is one designed for the TV channels to be received in your area. This is because all of the metal work will get used. This gives greater sensitivity to the channels you want and less to the unwanted ones. [/b]
Installation of a Digital TV antenna means that ABC1 analog cannot be received along with GWN analog ifrom Bunbury and Kambalda.
“Antenna Replace”
Pale Blue background, red print.
A change in UHF band. Only replace antenna if the signals break up which may be weather dependent.
All analog channels within the antenna channel range will be receivable.
Cabling
It should be quad shielded RG6 with F connectors at any joins.
This is to minimise the pick up of electrical switching and TV signals other than picked up by the antenna.
Masthead amplifiers Should only be considered if the measured digital signals show there is too little signal. If that is not an option try the above techniques first.
Recognising interference
Better Television & Radio Reception
Please note this is general information. Use an antenna installer who can measure and error rates of digital signals (They should be able to give you Bit Error Rates (BER) figures of less than 8 e-4.) If they cannot do this, get someone else.
Apartments and retirement villages use Master Antenna TV systems (MATV)
MDU Handbook. This document is designed for presentation to the Body Corporate or the building owners.
Remember that analog transmitters will be switched off between Dec 2009 Metro, and 2013 in the last regional areas.
These systems contain amplifiers for individual channels. In any non-digital installations you will generally find some digital channels are not receivable due to this filtering.
Prior to upgrading or installing an MATV system make sure all receivers are digital or have a set top box. This will mean that the channel amplifiers can be retuned or replaced rather than installing another set of 5 amplifiers. Then specify that the installation must conform to
Australian Standard 1367-2007. This will ensure that all digital channels will be available, including HD and surround sound when available.
Radio – FM, DAB and DRM
FM
None of the antennas listed above are designed to receive FM radio. The best way is to have an independent system Please read FM Antennas[/u]
DRM is another type of digital radio which will replace AM radio and will not use any of the above equipment.

Satellite stations available
The programs on Aurora are transmitted through the satellite in digital form using DVB-S transmission and MPEG-2 compression, but in some towns are then retransmitted in analog. A home satellite receiver will receive the signal in digital, however there is none of the enhancements such as multi channel, wide screen etc.
The replacement for Aurora will use DVB-S2 and MPEG-4 compression and will be run by GWN, WIN and their Joint Venture TEN West, so an HD satellite receiver with an authorisation card is required. The programs will include the same number of programs that all other Australians can see.
