All,

Analog TV switchoffs are;
Brisbane 28th May 2013



A "Designed for Digital" antenna should not be able to receive ABC1 analog if your antenna is pointed at Mt Coot-tha. This excludes Boonah, Esk, Kooralbyn, Maroon, Mount Alford, Rathdowney, Somerset Dam and Toogoolawah.

With the exception of those viewers in Boonah, Esk, Kooralbyn, Maroon, Mount Alford, Rathdowney, Somerset Dam and Toogoolawah, from 2013/2014 the following channels will be used
TVQ 1# is using RF channel 11
ABQ 2# is using RF channel 12
SBS 3# will use RF channel 7
CTQ 44 will use RF channel ?
BTQ 7# is using RF channel 6
QTQ 9# is using RF channel 8

H3 type antenna is all that will be required for channels 6 - 12. This will be the cheapest antenna because no UHF or band 1 and 2 is not required. It will also mean that all the antenna is sensitive to the cnannels you wish to receive.

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!
Mainland State Capitals: TEN, Seven, Nine, and Briz channel 44 .
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.
H34
V5




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.

Bravo, Bravo Alan.

Could you put the a note too that anybody living south of Beenleigh should tune to Mt. Tamborine for better reception and anybody from Landsbrough and North should tune to Bald Knob, Dulong Lookout and Black Mountain

Hi Alan,

I have lived in houses at Joyner, Lawnton and soon Bray Park. I had major reception problems at Joyner and had the house re-cabled twice and a digital/analogue antenna installed - didn't really help the reception problems. I then tried installing a purely digital antenna with quad shield coax and f-type connectors just to the STB - still had interference. I have since moved to a house at Lawnton (approx 700m north) and my main problem is ABC HD. The house at Joyner was a bit lower, so i think that attributed to the interference problems. I am currently building a house at Bray Park. Is there anything special i should do since i have lived in three of the suburbs you mentioned in your post?

Thanks,

Jonne.

Hi Alan
I'm interested to know what antenna I should consider for receiving digital only in the Caboolture area. My STB tells me I have channels 6-36 scanned. I don't want the Fracarro brand as I want to use an F-type balun.

Thanks Alan

SBS DIGITAL TELEVISON in BRISBANE and the GOLD COAST

SBS wishes to advise that, as a result of reception complaints and the following measurements and investigations, a decision was made to change the antenna at the Mt Tamborine Transmitter from the metropolitan to the regional for its digital service. This change occurred in November 2006.

The antenna change has resulted in no SBS digital signals from this site reaching the Brisbane service area. Those reported digital reception complaints in the Brisbane service area have now been resolved.

Also as a result of this change, viewers to the north of Mt Tamborine transmitter site who were receiving its signal may now have lost their service.

SBS regrets any inconvenience caused by the loss of the service.

SBS is endeavouring to restore the digital service and will provide further information as it becomes available.

AlanH.

I note in your advice on TV Reception etc that you single out a number of north brisbane suburbs with issues to post here.

Quote:
" If you are in one of the following suburbs:
Bald Hills, Albany Creek, Bracken Ridge, Bray Park, Brendale, Brighton, Castledene (Carseldine) Deagon, Fitzgibbon, Griffin, Lawnton, Murrumba Downs, Nashville, Petire, Sandgate, Strathpine, Taigum, and are having problems please post on this strand."

I live in Carseldine and have very poor reception for sbs and briz 31. Is there any additional advice you can give for these areas. I have digital and analogue.

I am currently thinking about getting an antenna specialist out for advcie.

Cheers

Dogga

Is there patterning on your analog reception. If so which channels.
Does your digital reception break up, if so which channels.

Does anyone have suggestions for improving SBS reception? I'm located at Caboolture (east of Bruce Hwy), and my Panasonic TU-HDT206A reports that the SBS channels have a Signal Strength of 5%, and a Signal Quality of 25%, whereas ABC, Seven, Nine and Ten channels have 65%-95% and 100% respectively. My VHF/UHF antenna is directed towards Mt Coot-tha, via Bald Hills repeater.

Bald Hills is only a AM transmitter. It has nothing to do with television nor is it any relay tower. Your antenna should not be facing towards here, more so further west to Mt Coot-tha. SBS is on a UHF transmission and requires a good quality antenna. You really need to call in a technician as it sounds like you are very unsure about television transmission.

Hi PPL

Came across this forum by fluke hopefully it will help us out

we are in Mt cotton and have poor tv reception its watchable but sometime is pixeled are running 3 tv 2 with std set top box and the main one with a hd set top box

had some tv guy come out but his idea's where very vauge saying we should got 30ft up with a mask to try and improve the reception at a very hefty price and that may fix the problem

just wondering if anyone has any idea's or can recomenned a top antenna guy

I am experiencing the problem of dropping out on my HD FTA reception with the message bad or no sigal, which means i have to rescan my digital stations. I can only do this by turning off the TV and rescaning from stratch.
i replaced my cable from the wall socket with Quad shielded monster cable to the Belkin Surge protector and from the Surge protector to the aerial point on my Sony 40 inch LCD TV (just bought) which has an inbuilt HD TV Tuner. My analogue Reception on 7, 2 has ghosting and more pronounced ghosting on SBS.

From reading your various forums i have narrowed the problem down to my antenna which i share with another neighbour in my townhouse complex we have 4 antenna outlets to currently running tv's she has 4 outlets but only using 2 tv's at the moment. Her reception in asnalogue is bad on 7 and 10?

I don't think we have quad shielded cabling from the roof antenna to our TV antenna point. The antenna is about 9 years old.

Can anyone suggest a reliable antenna specialist in the Arana Hills, Ferny Hills or even just the Northside area of Brisbane who will do all the proper tests: digital signal strength etc, this i think will be the biggest hurdle.

If after all the tests are done and cables replaced is the next step a call to Sony under Warranty to have a look at the inbuilt set top box, of course if no problem is found with the box i will be charged.

Tech deficient,
What you need to do is to convince the other townhouse owners to buy STBs which start at around $50 each. Then the antenna can be replaced by one which is in the linked post to the first post in this strand. Surge protectors will not improve your reception.

I doubt that there is any problems with the STB, the problem appears to be insufficient signal. This is probably caused by splitting the signal so many ways. A distribution amplifer will probably be needed if not present at the moment.

AlanH I have a bit more information:Additional booster boxes were fitted one per block in the roof. The middle units (one each block) were fitted with an 'electric plug' that had to be kept turned on. My neighbour has the 'electric plug' in her unit and the box is turned on. My question: is the "electric plug for the booster box that is in the ceiling. I would not know if there is a distribution amplifier or masthead amplifier on our antenna. Could the Belkin Surge protector be weakening the signal to the TV.
As explained previously i have Quad Shielded (RG6) cable running from the FTA wall outlet to the Surge protector and Quad Shielded cable from the Surge protector to the back of the Sony HD LCD TV. Or do we just have too many antenna outlets.

I have been advised by the technician who installed the ceiling antenna boosters that the electric plugs located in the middle townhouses are to turn the boosters on and off. I asked him when he installed the boosters if he noticed whether the coaxial cabling was RG6 Quad shielded that we had running from the roof antenna to the outlets and if we did have a distribution or masthead amplifier?

He could not remember, but told me that using RG6 Quad Shielded was maybe overkill. So i dont think he even bothered to check the antenna on the roof when he installed the booster. I further inquired if he used a digital signal strength meter but he said he made an estimate of the signal strength with his analogue meter? My alarm bells started ringing after hearing this.

I questioned him further on the possible solution of a distribution amplifier for the roof antenna and was told maybe a plug-in wall outlet TV signal amplifier would do the job.

I will be getting an antenna specialist reccommended by the DBA to come and give me a quote, at least they hopefully will have the right digital equipment to test my signal strength and possible relocation and upgrade of my existing antenna.
I will approach my neighbour whom i share the antenna with about her possibly buying a set top box, she has foxtel and only needs the box for the two FTA stations 7 and 10. If the body corporate dont accept the antenna quote we will share the cost of the upgrade ourselves.

AlanH, Thank you for advice. My antenna technician came today and tested the digital signal strength at the antenna outlet on the wall as well as at the outlet on the surge protector and found good digital signal strength. He also inspected inside the roof of the neighbours unit i share the antenna with and found that a masthead amplifier was installed along with splitters for the various antenna points in the two townhouses. He said the antenna cables in the ceiling were RG59 type.

I showed him the ghosting on the various channels 2,7,10 and sbs of the tv's in both townhouses. We are in a low area with high trees in the line of reception to the stations at Mt Cootha some 15-20 klms away. He explained that the masthead amplifier already boosted the signal and that adding a distribution antenna would not improve our reception any more.
He advised my neighbour that a sd set top box would be a better alternative (as per your previous suggestion).
He did a digital signal strength test of the antenna on the roof and signal strength was ok.
As for my problems of the dropping out of the HDTV signals with the message bad or no signals, he experienced the same problem on his HDTV at Kallangur and told me that we only receive the one Digital Transmission from Mt Cootha and that television stations will eventually roll out more transmitters when the take-up of digtal becomes more popular upon the ceasing of analogue transmissions in 2010. (long wait). He has come across other people with inbuilt HDTV tuners who are experiencing the same problem as me. Would you believe they are buying free standing (external) HD and SD set top boxes to get the signal because these apparently have stronger tuners than the inbuilt HDTV tuners.
So a $3,000 TV is not capable of delivering the service we have paid for.
He said he could try installing another antenna on the roof that was not shared but doubted if this could fix the HDTV dropping out problem.
As a last measure i have contacted Sony and a service centre technician is coming out to inspect the HDTV tuner. I feel like saying to Sony to supply me with an external HDTV tuner to get me by until transmissions are improved. Maybe if this reply was posted on the HDTV forum we might discover similar problems with other owners of Sony HD TV's with inbuilt tuners.

tech deficient,

What did the antenna tech classify as 'OK'? There are several pro installers/broadcast engineers in these forums who would have a clearer picture (pun intended) of what may be happening in your case, with more detailed info.

It would be helpful if you could post what readings the tech recorded. eg: channel power and bit error rate (pre and post viterbi) for each of the digital channels, signal strength in dBuV for all analogue channels and FM radio and any other signals being picked up by your antenna... (communications, paging etc).

Also, is the RG59 cable solid core or 'air spaced'? Is it dual shield or single shield? What separation does the RG59 cable have from power and other cables in the ceiling?

What make/model is the masthead amplifier? Is it fully shielded? What type of connectors does it have... screw & saddle or 'F' type?

What type of splitters are used... screw & saddle or 'F' type?

How many outlets are there and what type are they... screw & saddle or 'F' type?

What make/model of antenna/s are installed?

Did the tech do a site survey on the roof to determine if the antenna/s is installed in the best possible location on the roof?

As you can see, there are many factors that can affect reception, and any antenna/distribution system is only as good as the weakest link in the chain.

Hi tech deficient

mtv is correct in posing the questions in his post. Your situation is unusual.
One thing you mignt be ablt to check/repair yourself is the RF socket/sockets. If they are PAL type as opposed to 'F' type they may have screw and saddle
cable terminations which a lot of 'sparkies' love to tighten up 'toooo' tight. This can have an adverse affect on signal strength.
In two recent cases I was able to increase signal levels at one house by between 3 and 6 dB depending on the frequency. I replaced the Clipsal outlet with an 'F' type socket in the same housing. Just pop out the existing PAL type.

This was enough to make UHF channel 40 watchable whereas previously 'NO SIGNAL' was displayed. It was a housing commission block of 4 fed with one broadband Hill antenna.

Of course there may be screw and saddle connections in your roof space which also might be at fault.

Good luck with the problem.

Tahoma.

I was going to get the antenna tech back for further signal readings as suggested, but maybe the inbuilt tuner is the problem after all.

We got an antenna specialist to put in a new antenna and run two out lets, one to the lounge and the other to the rumpus room.

he mentioned that the signal may be too strong and he would have to put in a attenuator. if you go to the front yard and look up the towers are less than a kilometre away.

last night i brought over a small TV with built in digital and analogue tuner.

the analogue i don't care about (31 would be nice occasionally) just the digital

there is no reception on channel nine or ABC (no signal) it says.

channel 7 comes and goes with the blocky breaking up thing

do i need an attenuator because I'm so close, or an amplifier, or someone recommended a filter, the same person said you can have one mast with two antennas
so you catch the signal from all the stations as we are so close.

Any ideas, opinions before i ring the antenna installer and try to sort it by spending more money.

I can't believe I'm reading this. If he is a specialist, then this comment wrt signal strength is bogus. Surely he would have measured all signals and adjusted accordingly.

It's not that hard, really, if you have the correct test equipment and a brain to match.

This should be covered by service warranty as it sounds like it hasn't been done correctly.
