All,

Analog TV switchoffs are;
All of Tasmania except those areas below, 9th April 2013

Remote Tas (Impaja, Southern Cross, TEN) 10th December 2013

Remote Tasmania is the yellow parts of the maps below
Southern Tasmania
Northern Tasmania
For those who live in the yellow area, can get authorisation for a VAST satellite receiver now. This will give viewers the same number of programs as is available in Hobart. See below.

Signal Sources

Terrestrial
broadcast transmission needs a TV antenna designed to cover only the radio frequency channels used by the transmitters on your local transmitter site.

Satellite broadcasting need a "Ku" band antenna dish for Australian broadcasting (Pay and Free to air). All domestic systems are encrypted.

Internet provides the user requested program downloads from ISPs or program providers.

Disc replay Blu-ray and Digital Video Discs are not covered here

All digital transmission systems will either faithfully reproduce what is being sent, the pictures will breakup into blocks with sound going on and off or a frozen image and silence. The frozen image can be replaced with a "no signal" sign. This is often called the digital cliff and can occur if the signal is too weak or too strong. Other than this the antenna system does not affect picture or sound quality. High Definition and Standard Definition signals share the same transmitted signal.

Obtaining broadcast signals.


Determine the most likely source
1. Type your exact street address.

2. On the "MySwitch" website click on the "Transmitter Information" on the lower left side. Compare the previous map to the current map. If both transmitters are in the same pink or blue colour pick the transmitter closest to you. Viewers in the Northern Beaches, northern shore of Sydney Harbour between the bridge and the heads, Eastern Suburbs and those in the suburbs between the CBD and the Airport must do this.

3. Now click on the ACMA Out of licence area reception form B58

Subsidies Beware that subsidies are available for those on full pensions and those who have been using an analog translator which is not converted to digital. The subsidy is not available if you buy your satellite receiver more than 6 months before analog switchoff in your region. Subsidies are not available if you can already view digital TV. DBCDE Household Assistance Scheme and DBCDE Satellite Subsidy Scheme

Determine the type of receiver required for digital television
There are two groups of receivers
Ground based (Terrestrial) transmission or Satellite Based Transmission

Terrestrial receiver
This receiver should be capable of receiving the following program streams;
All areas: ABC1 – ABC3, ABC24, SBSHD, SBS2, One, Eleven, 7Mate, 7Two, GEM, Go!
TEN, Southern Cross, WIN

This receiver TV, Personal Video Recorder or Set Top Box is usually called HD and should comply to
Australian Standard 4933.1-2010 Digital Television – Requirements for receivers – VHF/UHF DVB-T Television Broadcasts. (High Definition, MPEG4 capable)
Do not buy Standard Definition Set Top Boxes as you will not get a full range of programs. High Definition Set Top Boxes can provide signals to old type receivers.

Satellite Receiver

Those who are currently using Aurora, will have to replace this receiver by the end of 2013. If the dish, cabling etc are ok, only the receiver needs replacing. Replacing the TV with a new widescreen TV will show the programs in the best quality.
VAST Receiver Specifications.

Reception is only possible when authorised. This is covered later in this post.

Antenna signal distribution from the antenna
In single dwellings a splitter may be used to feed up to typically 4 outlets. (However, this depends on signal strength as splitters reduce the signal strength.)

Multiple dwelling blocks use Master Antenna TV systems (MATV) which consist of a single antenna followed by an amplifier, which in bigger systems use a separate amplifier for each terrestrial channel. Satellite MATV systems also contain a pair of amplifiers, one for vertically polarised satellite signals and a second amplifier for horizontally polarised signals.
MATV systems can also carry digital radio signals. (DAB+ and DRM+)

Please note that channelised MATV systems the amplifiers have to be replaced or retuned to the new digital channels.

Antenna Installers
Use an endorsed digital installer.
List of installers' names.

There is a new Australian Standard for TV antennas AS 1417.1(Int)-2011
All installations should be to Australian Standard 1367:2007 (ignoring the analog TV requirements) These standards is not compulsory but ensures reliable reception in single and multiple dwellings.

For MATV systems please read this handbook.

Which antenna should be installed?

From the map on "MySwitch"
Dark Pink indicates prime reception area. Antennas with only a few dB are ok if they are elevated outside
Light Pink High gain (highest number of dB)
Dark Blue Use the blocked signal path recommendation with a masthead amplifier. Antenna may be
Light Blue Use the blocked signal path recommendations with a masthead amplifier. Antenna is 10 m above the ground.
Note: These recommendations are subject digital signal measurements to the requirements of AS1367:2007 (without analog requirement).

Don't Get Ripped Off! Do not install antennas designed for analog channels 0 – 5A. About 30% of the metal work will or is not used any more. Furthermore these antennas can make reception less reliable. The antenna should not be more than 750 mm wide.

Antenna Types Drawings

Whilst they still exist, analog channels within the antenna channel range will be receivable.

Read the Transmitter List

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.

"Antenna Replace"
White text on red background
This shows which sites have analog transmissions on channels below channel 6.

"Antenna Replace"
Red print. on pale blue background
A change in UHF band. Only replace antenna if the signals break up which may be weather dependent.

Write down the antenna type for the transmission site you wish to use.

Now click on the antenna type from the transmitter list to see your options for your antenna.
HWb
H5
H4+
H4
H3

V5
V4+
V3



Caravans/Marine Band 3, 4 - 5


Digital Dividend – The selling of RF Channels 52 – 69 will require changes in the channels used. The required channel changes will occur in 2014.

The plan is for a pair of national broadcasters, three commercial broadcasters and a community broadcaster. This uses 6 channels.

The plan is to put all the transmitters on a single site into one of these groups
Using the Antenna Types in the transmitter lists these types fit the new channel groups.
H3 or V3 Channels 6 - 8, 10 – 12
H4 or V4 Channels 28 – 33
H4+ or V4+ Channels 34 -39
H5 or V5 Channels 40 – 45
H5 or V5 Channels 46 - 51
The ACMA is trying to restack the digital channels on each site to be within the antenna type already in use.
This will remove the requirement for Channel 27 – 69 (HWb and VWb type) antennas so that more sensitive narrow band antennas can be used for no change in price.
Hopefully this will remove the requirements for C## type antennas. This only applies to Canberra, Manning River, MIA, Goulburn Valley, Wide Bay, Gladstone East.
* Example 1: Darwin will not require any changes because they are already using channels 29 – 33.
* Example 2: Main transmitters (shown in bold) in mainland state capital cities require an H34 antenna. In 2014 SBS and community TV will change to band 3.
Then the best antenna is only an H3. Existing H34 antennas will be fine for the rest of their natural life. This does not apply to translators.

It is the Building owner's responsibility to upgrade to digital reception. See MATV above. This also applies to rental houses.

Indoor Antennas

Indoor antennas generally produce unreliable reception; however here are some guidelines if you wish to try one in a prime reception area.

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.

Radio – Digital radio and FM

Digital Radio
DAB+ used in all mainland state capitals, with trials in Canberra and Darwin. Use a band 3 Yagi-Uda antenna with its elements vertical with respect to the horizon.

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

DRM+ if used will use what was being used for analog TV channels 0 – 2.
DRM30 is another type of digital radio which will replace AM radio and will not use any of the above equipment. Not on

Free to Air Satellite TV – Viewer Access Satellite Television (VAST)

This satellite service is paid for by the Commonwealth Government to provide TV to remote areas of Australia. There is 3 licence areas
Southern: It covers inland NSW, SA and small areas of Victoria and Tasmania.
those who can prove that there is insufficient signal available at 10 m above the ground.

People receiving signal from Mt Barrow in NE/NW Tas still require B3 antenna for analogue TV reception.

Best to remove the old B1/B3 monsters and put channel 9 only or B3 antenna in place, makes for a neater installation. Of course, can use B3/4/5 combination antenna if signals of sufficient strength.

Impulse noise from HT power lines can be a challenge here on analogue 9, usually in summer and in poor reception areas.

To add to the above, some of Deloraine (if not all) and some of Dunorlan can also get digital reception off Mt Barrow.
Also Fracarro antennas can be purchased from AI Electronics 165 William St, the 4 ways, Devonport (used to be a Dick Smith agent, now Jaycar agent).
The Antenna they have is the LP345HV, just ask for an LP345.

anyone know about reception in primrose sands?
My parents are building there and just asked me to research theyre options (i live in wa)
i've been there and from memory i think they might be able to get reception from mt wellington. but i was there about ten years ago, might have changed since then.

smdoherty,
If you click on the coverage area map for Mt Wellington on the first post in this strand you will find it is in the strong signal area.

Use some of the antenna recommendations in the same post. Note all digital transmissions from Mt Wellington are in band 3. There is no UHF.

we are at latrobe, bought a centrex standard definition top box, have not changed antenna, the box wont pick up any channels.........
We were told by a local guy that latrobe had it,

what am i doing wrong....


All,

Tasmanian Transmitter Listing Digital and their equivalent Analog

The following transmitters cover Regional Tasmania
Main (High Powered) Transmitters (Mt Barrow)
Station call sign, Logical channel number which appears on the front of the STB, Real (RF) channel number.
Mt Barrow coverage area map
ABNT (2)41, SBS(3)44, TDT(5)52 TNT(6)38, TVT(8) 50, Spares 41, 43, 46
These stations require a band 5 antenna only. Horizontal polarised. The existing band 3 antenna can only add digital interference. So connect it to an FM radio.

For startup dates

Antenna Groups - Digital and Analog

The following list of recommendations is restricted to the channels being used in this area. This will minimise interference and maximise the signal from the antenna to these stations. It is better to get the strongest signal from the antenna prior to considering amplification. Prior to adding amplification it is best to get an antenna installer to measure the Carrier to Noise ratio and the Bit Error rates on the roof to get the best antenna location and to decide the amount of amplification which is required. Excessive gain can give a "No signal" sign from the STB. The masthead amplifier should contain filters to restrict amplification to the channels in this area.

Antenna Recommendations
Main Station
Yagi
Fracarro 20RD5, 11-14 dB
Hills TMX18 B5, 11-16.5 dB
Matchmaster Wisi EB66 Ch 38-69, ≤16.5 dB (29º acceptance)

NAS ANTSXU49-69/18 Ch 49-69, 14 dB

Log Periodic
Fracarro LP5HV, 9.0 dB


The above antennas will not receive FM radio. The reason for excluding analog ABC is that any RF channel below channel 36 is more likely to pickup power line and car ignition interference. The lower the channel number the worse the problem. The interference shows up as pixellation and plopping sound.

Band 5 Horizontal
Launcestion, Barrington Valley, East Devonport, Ulvestone. See the main transmitter list.

Band 5 Vertical Burnie, Lileah, Meander, Port Sorell, Smithton

See Antenna design basics for difficult installations

The higher the number of dBs the more sensitive.

The last option is indoor rabbits ears which are stretched out in a straight horizontal line. For RF channels the total length for band 5 is 215 mm. The mounting should be centred. The polarisation as as mentioned above. If it is horizontal the antenna should be rotated so that it is at right angles to a line between it and the transmitter. If vertical it is irrelevant. Typically 0 dB unless there is an amplifier in the base.
Finally for further information,

Consult DBA - Apartments for further information about houses or DBA-apartments apartments.
Antenna Design Basics


If an antenna technician can prove no TV signals are available, then a free to air satellite receiver is an option.
Stations available
ABC: Satellite programs generated in (Brisbane?)
SBS: National programs ex Sydney
Impaja (Nine & TEN networks) from Alice Springs
Seven Central(Seven network) from Townsville

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.

Radio is also carried digitally, 4ABC Radio Regional ex Brisbane, 4ABC Radio National ex Brisbane, and commercials 4BRZ (Breeze), and 4RBL (Rebel FM) ex Beaudesert These signals are retransmitted in some towns on FM.

johnandsteph,
I clicked on the Mt Barrow coverage area map and it shows you are in the outer coverage area. The East Devonport translators are yet to be commissioned. I do not know what antenna you are using and whether there are hills to your east. Also I do not know what cable you are using and how old it or the antenna are.

I would use the diffuse signal recommendations. If that is insufficient, then a masthead amplfier of the recommended type may be needed. Some height above the roof is also a very good idea.

This is the complication of the the fact that what the ACMA regards as band 5 and what the Europeans think is band 5 are different. Just like they do not use channels 21-28.

I try to avoid 21-28 because this band is used for UHF CB etc.

Hi all,
This is info you may already know however, as I'm new to this site I'll tell you anyway ! I live in Penguin, Quin Street overlooking footy ground- great view of ground and sea- but no outlook to the east, ie Mt Barrow. I brought a digital set top box, plugged it in- no go. Thats not unusual, so I brought an antenna from Lacey's at Ulverstone, put it up, connected it and bingo- perfect picture all channels- but the surprising factor is it is pointing west- towards Burnie. They say there is no signal from Burnie yet. I brought a second set top box ( and antenna) - took it to Evelyn St Penguin, west side of Mission Hill in a bit of a gully but with a westerly outlook(lots big gum trees). Once again got digital channels OK- almost where ever the antenna was pointed but best was from Burnie ! I loaned box and antenna to my neighbour who has had problems with TV reception despite Epsom Rd Analogue signal just up the road. Glen was setting up the gear for a test- had the antenna etc sitting on his bbq, not even in the air- and got digital pictures! Best was from Burnie Direction. I know others in Penguin get best reception direct from Barrow,.. A friend of mine lives at Applebey's Rd- on way to Port Sorell- probably 5 minutes west of Port Sorell- they get all channels direct from Barrow. ( and I expect you would as there is nothing in between them!)
I have noticed set top box gets out of sync with mouths- I re-set this by turning box off and on again. This works for awhile.
Cheers

Telenut - you have discovered one of the perks of digital transmission, namely receiving a quality signal from a reflected source!

I have some clients south of the Bass Highway at Penguin, in the dip west of Ironcliffe Rd and they are receicing digital by pointing the antenna at Ron Gee on Mission Hill. Obviously this is a reflected signal as we all know there are no translators west of Launceston (I was going to say west of Mt Barrow but we do have Juliana St in Launnie!). This is producing some lucky customers like yourself, especially now that Mt Barrow is transmitting on full power. :blink:

If more people find out about this then there may be no need for any translators along the coast! :D

What most of the public neglect to do when redirecting their antenna to Mt Barrow is failing to change the polarity of the antenna. All analogue translators from Penguin and further west are vertical polarised and the Digital signal is horizontally polarised.

BTW - the Epson Rd analogue translator leaves a lot to be desired. Clients in Crisling Pl have had problems getting a quality reception from that translator and its less than 500 metres away! They have gone for digital reception!

question for you, can you get tdt digital tv from dunorlan, i am at christmas hills area'

thanks

Damn forgot all about this thread.
TDT is fine as is all the other digital channels, but I am line of sight with Barrow because I am on a hill.

Christmas Hills is a pain because the end of the hill gets in the way for most residents.
Better reception for analogue can be had from the Gardners Ridge transmitters over towards Needles (South West from Christmas Hills).

SBS is channel 53
ABC is channel 56
Southern Cross is channel 59
and
Win is channel 62

With a bit of luck ABC and SBS should have digital transmitters on Gardners Ridge within 6 to 12 months.
I would think the FTA commercials will follow fairly quickly if not precede the ABC and SBS.

Oh and Sheffield (from Mt Claude) now has SBS digital with ABC being only a month or so away, hopefully.
Hardware is in the building it just needs commissioning.

ABC and SBS digital Mt Claude have been running for some months now.

HOW TO GET THE BEST RECEPTION
To get the best reception connect a hills AVA, a Kingray MHV34, or a Kingray

MHV44HLG booster (depending how bad the reception is on band 3 and if you want to

boost band 1 & 2) to the vhf input on the Kingray DPOUV diplexer (it should have

power pass on both inlets) then connect either a Kingray MHW34. MHU34 or a MHU44

OR MHU44B5 booster (depending how bad the reception is UHF) to the uhf input on the

Kingray DPOUV diplexer then connect a Kingray PSK08 power supply straight to the

output of the DPOUV diplexer if you only got one TV or connect a splitter to the output

of the DPOUV diplexer then connect the power supply to the outlet of the splitter that has

AC/DC pass that way it’ll send power to both the boosters and it’ll send a signal to every

TV in the house or shed

IM NOT SURE WHICH ANTENNA YOU WOULD NEED IT DEPENDS ON THE AREA BUT MOE LIKELY A CA16 OR A DY14 FOR BAND 3 AND A TMX 16, TMX18B4, TMX 18B5, TMX20 OR A PHASED ARRAY UHF ANTENNA BUT FOR BAND 1 AND 2 DEPENDS ON THE AREA SO IF YOU WANT TO KNOW WHAT ANTENNA YOU NEED PLEASE SAY THE AREA YOU ARE IN AND HOW FAR AWAY FROM THE STATIONS YOU ARE SO I CAN GIVE YOU SOME IDEA YOU MAY NEED A BAND 1, 2 AND 3 DIPLEXER IF YOU ANRE IN AN AREA WHERE THERE IS LOW FREQUENCY CHANNELS AS WELL AS BAND 3 VHF

You're not Tyrewarmer 20 dodgy by any chance?

Before deciding what is required to provide the best reception, first you must know what signal levels and quality are present at a given location.

The key to digital reception is obtaining signals of adequate power and quality At THE ANTENNA.

Amplifiers should only be used to compensate for distribution losses, not to try and increase signals which are too low/not present.

Over-use of amplifiers without prior knowledge of signal power and Bit Error Rates is almost guaranteed to not only amplify existing problems, but to also create new ones.

Selection of the correct antenna for a particular location, together with accurate digital measurements to locate the best mounting location for the antenna are things which make every installation unique.

A "blanket post" across every regional area DTV forum recommending such bad practice may be considered 'trolling'.

As you are a new member, having only joined the forum today, burnoutking2 perhaps you could share with us your location, what channels you are receiving and from where, and what antennas and amplifiers you are using to achieve this.

I have my suspicions this poster is closely related to recently suspended troll, tyrewarmer20/dodgy

I have a very good airal but can no longer get any digital channels we had them yesterday. This started this morning the 18th april. Is anyone else having trouble with no signal? Are they doing something to Mt Barrow? We live in Branxholm. If someone can help I would be grateful.

Hi, I am new to the topic. (and I accidentally posted this originally on the radio forum)

I live in George Town TAS behind 'The Buffalo'. (a large hill)
I have good digital reception on the commercial stations but next to none on ABC and SBS.
I had an antenna installer visit and extend the antenna vertically on the roof of my house when I first moved here, but he 'didn't believe in measuring the signal strength' preferring instead to go by 'experience'.
My reception hasn't improved.
I have a Hills mast-head signal amplifier (left by previous owner) and when it is turned off the analogue signal all but disappears.
I think I should have someone visit and measure the signal, assess my antenna type/s and direction/s and give advice on what the most appropriate next step should be.
So that I don't waste my time (and $), is there an easy answer as to what sort of antenna I should have?

Any advice is welcome.

Flashman,
If you read the first post in this strand "Get the best reception" and you look at the Tas link you will find that Mt Barrow requires for digital a band 5 antenna.
Since you have a hill in the way you need the diffuse or long distance recommendation for horizontal polarisation. This is a phased array. I would also probably also add a masthead amplifier if required which is designed for band 5 only. This will not be your existing amplifier. The links in the post above will give you the information you require.

If you turn off masthead amplifiers you will get less signal than if the amplfier was removed completely and the wiring reconnected.

You may also wish to add an FM antenna for all ABC radio and some commercial stations as well.

Can't be done in situations like yours. Some can "talk the talk", but not "walk the walk".

My reception hasn't improved.


So how was "experience" used to explain this?

I think I should have someone visit and measure the signal, assess my antenna type/s and direction/s and give advice on what the most appropriate next step should be.


Agreed. Someone competent, with a digital field strength meter, and experience in difficult areas, preferably with some local knowledge as well.

So that I don't waste my time (and $), is there an easy answer as to what sort of antenna I should have?



Hopefully this competent person will have a range of antennas and the means to make the most appropriate selection.

Any advice is welcome.


I do installations for this type of situation, but not in your part of the island. If reception via a direct path transmission is not possible, it may be necessary to obtain digital signals from a suitable reflecting point, although this can be fraught with difficulties. It may also not be possible to obtain recepion for all the channels you require.

You've pretty much answered your own question.

The best type of antenna would be best determined with a site test, to see what signals are available and what is needed to give you the best possible result.

You may also find the amp is not suitable for digital reception and may also need to be replaced, or even just removed.

Once again, any competent installer should be able to test your antenna etc and advise you further.

Thanks Guys, I have read a lot of the info you have posted over time and will continue to do so. It gets very technical doesn't it!
Can you suggest anyone to measure the signal strength and / or perform installations in the Launceston district?
