1/10000 what somt of ber is that?
Next point, a ber of e03 will work provided the actual number of uncorrected errors coming through is basically non existant (this is the point where the picture breaks up).
read about cliff edge in relation to ber, go look it up and then post.
suggest that some instruments are more sensitive than others hence I have an ap01, which is of course more senstive on lower signals than the t40 I have.
Not to mention reed solomon uncorrected, these are the actual errors. Furthermore there are pre and post viterbi ber.
Analog TV switchoffs are;
Mildura/Sunraysia between 1st January - 30th June 2010
The rest of regional Victoria between 1st January - 30th June 2011
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.
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.
Click on Transmitter List to find you likely transmitter site(s)
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.
2. Select the antenna type
From the spreadsheet use the antenna type to select the link below
Band 3, 4 - 5
Antenna Type Drawings

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.

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. This means that ABC1 analog is not received in Upper Murray, Orbost, Myrtleford, Central Victoria (Bendigo), Colac, Cobden, Murray Valley (Swan Hill), Nhill, Coleraine, NWarnambool and Western Victoria.
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.
Better Television & Radio Reception
If you are within 6 km of the guyed lattice towers at Horsham. Please report his on this strand for further advice.
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 1 in 10 000.) If they cannot do this, get someone else.
Apartments and retirement villages use Master Antenna TV systems (MATV)
Remember that analog transmitters will be switched off between Dec 2009 Metro, and 2013 in the last regional areas.
Australian Building Codes Board Digital TV Antenna Systems
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
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
DRM is another type of digital radio which will replace AM radio and will not use any of the above equipment.

If an antenna technician can prove no TV signals are available, then a free to air satellite receiver is an option.
The programs are transmitted through the satellite in digital form, 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.
