Get The Best Reception: Mildura/sunraysia

SBS World News is on LCN 33, not LCN 31, LCN 31 redirects to LCN 3

The following post uses the information from Get the best reception: Regional Victoria
Yatpool is the main transmitter for this area Coverage area
ABMV 11 carries ABCHD, ABC1, ABC2 shown as logical channel numbers 20, 21 and 22 respectively.
SBS 28 carries SBSHD, SBS1 and SBS2 shown as logical channel numbers 30, 3, 33
MDV 33 carries TEN HD & SD programs shown as 50 and 5
PTV 31 carries Seven HD and SD programs shown as 60 and 6
STV 7 carries Nine HD and SD programs shown as 80 and 8.
All of the signals are horizontally polarised.
So when you use the installation scan for signals you should see channels 7, 11, 28, 31 and 33. These signals will then receive the logical channel numbers above. These are used to select the programs.
For the most part existing antennas in good condition will produce these signals. If the signals break up new antennas should be Band 3 & 4". Yagis are the best type except for long distance reception (outer edge of the blue area on the coverage area maps where phased arrays should be used.
Masthead amplifiers may be needed on the edges of the coverage area.
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.
Those who are in multidwelling buildings such as hotels, motels & apartments need to test each outlet and if reliable reception cannot be obtained then read Australian Building Codes Board Digital TV Antenna Systems
Underbool translators Analog only
The current analog transmitters are being funded by local government. I suggest that Underbool residents lobby the council for digital translators.
ABMV ? carries ABCHD, ABC1, ABC2 shown as logical channel numbers 20, 21 and 22 respectively.
SBS ? carries SBSHD, SBS1 and SBS2 shown as logical channel numbers 30, 3, 31
MDV ? carries TEN HD & SD programs shown as 50 and 5
PTV ? carries Seven HD and SD programs shown as 60 and 6
STV ? carries Nine HD and SD programs shown as 80 and 8.
All of the signals are vertically polarised. It is likely that a UHF phased array will be needed for analog and digital reception.
Apartments and retirement villages use Master Antenna TV systems (MATV)
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.
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.

To take this a stage further, Underbool is in the Mildura Rural City Council area. The council is a member of the Municipal Association of Victoria.
The Municipal Association of Victoria is the peak state based organisation of Victorian councils who can better represent these issues through their membership of the Australian Local Government Association.
Still confused, you bet I am.

I also think you should get the council to contact the Switchover Taskforce in the Department of Broadband, Communications and the Digital Economy and ask them about digital conversion of the Underbool translators.
I would be interested in their replies.

IThose out of range of the above transmitters will need to use the VAST satellite using a DVB-S2 receiver which is capable of MPEG-4 decoding

With the release yesterday of the Ministers carefully crafted press release, it seems that a direct to home solution is being announced. This is the link
To quote the press release, " . . the establishment of a new satellite service, which with the co-operation of the broadcasters, will extend viewer access to digital TV throughout the Mildura licence area . . . "
The new satellite service could be standard definition Freeview content with the preference for a Freeview badged receiver to allow recording of programs from the EPG!.
Of course any DVB-S receiver will be adequate if you do not want to record. AND WILL BE A DIRECT TO HOME SERVICE AT COST TO Joe Public unless you qualify for the assistance package and all our rural and regional towns and villages with self help installations will become mushroom farms.
The cowboys are back in business. Is there a local council planning requirement here for new dishes?
What about local content?
It's not getting any clearer
Still confused - You bet I am.

I still can't understand how someone can write such abundant information and not check it first ( alan):
" If the signals break up new antennas should be Band 3 & 4". Yagis are the best type except for long distance reception (outer edge of the blue area on the coverage area maps where phased arrays should be used. "
Alan can you let me know of any antennas that do both these bands that are either yagi or phased array.
I know of only two types:
hybrid/combination type antennas (generally inferior)
and log periodics.
Which is better is debatable and usually either of these three can be better or worse on a site for a variety of reasons (flatness and front to back ratio (log periodic), capture area and narrowest beamwidth on vertical (phased array), or gain and return loss (yagi). Specifically only the log periodic does both bands 3 and 4 and is therefore most cost effective as only one antenna is required.
As for used phased arrays at a long distance that depends on your issue. The answer is something like this. Unsure of what you need? Get a professional. A site test is a prerequisite by a good technician with good knowledge and good test equipment.
As for make sure every join is f connector - are there not other methods that are also quite good eg belling and lee connectors? Do not tv wall plates use these, or even better don't join the cable - It's actually better not to if possible. Common sense of course is that a hole in the wall with coax coming through is ugly!
I've often done someone's home and seen 3 different pieces of coax joined together. Sometimes they even use f connectors.

There is a link H34 in the pinned post which goes to antenna choices.
The reason why Fracarro Log Periodics are not there are;
Excessive frequency range.
It leads to lower gain and non rejection of interfereing signals. (Fracarro uses dBi for a gain reference which is 3 dB higher than the dBd gain with respect to dipole used by others)
If Log Periodics are so good why does Fracarro have so many UHF Yagis in their range? Why do they have phased arrays? Band 3 Yagis?
Dual Band Yagis for band 3 & 4 only.
Narrow bands improves gain and return loss.
Rejects interfering signals
I agree with the Log Periodic/Yagis designed for channels 1 - 69 are much worse.
"Get a professional. A site test is a prerequisite by a good technician with good knowledge and good test equipment." How does the viewer know what they are getting. There is no qualifications or certifications in the installation industry. To try and counteract this I have always recommended that a viewer ensure that the installer has a digital field strength meter.
Unfortunately there are many installers who know little of the RF characteristics of antennas and tell the customer that they have the best reception possible even if the wrong type of antennas are used. This is particularly true where vertical polarisation is used.
