Get The Best Reception - Gold Coast

Recommended Posts

Hi All

.......When the digital signal is lost it is usually for long periods of time (couple of hours), and the analogue gets more snow which is barely watchable if at all. It is snowy all over but with thick bands that have more snow, it is not lines....

all help is appreciated

Me thinks here lies the clue

Me thinks here lies the clue

Tony,

Do you have a 'booster' in the system ?

If you do this is a bit of a long shot , the power pack that supplies the volts to the booster may be over heating for some reason and the thermal safety

cut out in it could be shutting it down, no power up the coax, no Digital tv , extra snowy Analogue, then after a while it cools down the cutout resets and

power is restored and the pictures are back until the cycle starts again depending on the ambient temperature how quickly.

Tazzy.

Get the impression that TonyC is in a bad reception spot so assuming that there is most likely a masthead amp.

I'm thinking along the lines of an intermittent filter cap (or dry joint on it ) in the masthead amp assuming its fed from an AC power injector.Seen this before.

That causes the "bands of snow" and screws the BER on digital .

If this is the case ,using a DC type power injector (Kingray PSK06 for example) may provide a band aid solution.

Hey TonyC , was the mastheads amp replaced or are you still using the original ?

Have also seen corroded connections on plugs/sockets/splitters /connectors ,cause fairly similar results where a masthead amp is used with an AC power injector.

If its this then don't piss about trying to "clean them up" ,chop them off and replace them .

Ok I have now changed the direction of the antenna and aimed it at tamborine which has helped in that we have tv every night. Admittedly digital does drop out occasionally and it does pixelate sometimes, but it is beeter than losing all stations for the night. BTW I can now get local news yahoo

The antenna is a Poltec LP 35 (climbed on the roof) is that a good product? Should I look to change it for something better? if so, why?

TonyC,

If you want to completely remove the breakups you need a band 5 only antenna. (Particularly when it is raining) Roughly half this antenna is not being used to receive the Mt Tambourine signals.

As I said use one of the antennas recommended in the H5 link in the first post of this strand.

Most likely, however:

In a poor reception area, the approach is to test with a number of antennas in a number of locations to find the best spot to mount the most suitable antenna.

At the same time, the amount & type of amplification, if required, can be calculated.

At UHF, moving an antenna 50mm (and sometimes less) in any plane, can have a marked effect on received signal levels.

A DIYer might be able to get it right, but let me tell you, I done some pricks of locations where it can take up to a couple of hours testing before I either go ahead, or give up, on a terrestrial reception solution. :)

I have recently moved to Pacific Pines and after the antenna man installed a new antenna and booster I have excellent reception.... sometimes...

Hello Tony C

Having now read all of your input from the research and testing you have done and considering you engaged an antenna installer to set this up for you, it is quite legitimate for you to get the installer back and get him to reconsider his decision to set up your home for VHF Brisbane reception. If this occurs he should re-evaluate reception of Mt Tamborine with a UHF only antenna being used.

Your ability to easily improve reception as compared to that left by the installer, does raise concerns over the skill level of the installer himself.

I just hope he is willing/capable of correcting this for you with a suitable antenna and it should be at his cost.

^^^^ What he said!

Why he would choose to use Brisbane as a source is beyond me, as you would also not receive the extra Gold Coast channels, Prime 7 (CH6), SC 10 (CH5) and NBN (CH8).

Installers like this should be named and shamed IMHO.

Hi

I'm possibly going to ask THE most rediculous question/s given my complete lack of AV knowledge - but here goes !

We have just moved to the Gold Coast (Broadbeach) and living in a high rise apartment (19th floor - the lounge room faces N / NW with aluminium railings)

We have an early generation Samsung 46" HD DTV (about 8 years old). It is having terrible trouble tuning into any fta tv, whereas the cheap little newer tv easily gets all stations (except 7 I think) with $1 rabbit ears. We bought a "$42 crest indoor digital tv antenna - mini amplified" and it was next to useless and worse than the rabbit !!! We have a direct line of sight to Mt Taborine reception towers !

Now when we move the Samsung tv to a different bedroom (one that faces more towards Coolagatta S / SW) we are able to get some reception with rabbit ears - but still not ch 7.

One of my queries is to do with using the Foxtel cable system that is installed in the building !

We are using the foxtel cable connection for our cable internet with Telstra. Could we also plug into the Foxtel and use the cabling as an "antenna" "??? I have heard this can be done !!!

Any assistance would be greatly appreciated :-)

hi

If you have line of sight to the tv towers and an indoor antenna with an amplifier built in you may be overloading the tuner in the tv with signals or picking up some local interference which in turn is creating problems for the quality of your signals. If the amplifier is adjustable turn it down to minimum or better still off and see what happens.There must be a tv plug in there somewhere connected to an antenna system for the whole building ?

Foxtel is generally satellite signals only nothing to do with FTA tv signals, how many tv outlets are in the wall plate you think is Foxtel ? one maybe FTA tv ?

Lancers

Your transmitter site is Mt Tambourine. There will be a retune on 28th October this year. Rabbits ears are useless for UHF.

Try http://www.jaycar.com.au/productView.asp?ID=LT3114 or http://www.dicksmith.com.au/antennas/indoor-vhf-uhf-fm-tv-antenna-dsau-l0114. Keep the rabbits ears retracted. The loop is the UHF section.

On the southern side of the building there is another set of transmitters in Springbrook National Park.

You will have to disconnect the antenna, go to the installation menu on the TV and scan for all channels and let the receiver completed. This will erase any remembered channels. Connect the antenna and make the loop so that it is roughly north south along its axis. Now repeat the scan as before.

After 28th October do a rescan as above which will be necessary anyway, then take the TV into the southern side and do another rescan. This time all channels may be given numbers from 350 upwards.This is because the transmission channels from Mt Tambourine and Billbrough lookout are different but carry the same programs. This is the only way the receiver will know which channel to tune when you use your remote control. It would be easier however to have two TVs, one in each room. They have dropped a lot in price since 8 years ago.

You should be able to receive, ABC, SBS, 7 network, nine network, ten network, Prime, NBN and Southern Cross. programs from both sites.

Thanks Tassy and alan

We went and got a $40 digitech LT-3206 antenna with built in amplifier from jaycar.

We also splurged on a new 55" uhd tv and this is working great from the "problem area" in the lounge with the balcony.

Alan - the LT 3114 is the basic non amped antenna. Are you saying that the rabbits are not required for digital tv and it is just the loop that is picking up the signals?

We have moved the troublesome Samsung to the bedroom on the south side and it appears to be working with the $1 original broken rabbits-so I will probably purchase a 3114 as you suggest.

Ps. We had to manually tune both tvs to the frequencies to get the best results.

Lancer,

I did not say that rabbits ears are not required for DTV. They are in areas where VHF are used like Brisbane and other areas. In the Gold Coast UHF not VHF is used. I specifically specified a non-amplified antenna because you must have line of sight to Mt Tambourine and the transmitters is reasonably powerful.

Sorry to say that you paid too much for the antenna because the amplifier is not required.

Afternoon,

Apologies if this has been asked/answered, however have looked and cannot find the answer.

With the onset of Daylight Savings in NSW and NOT QLD, is it possible to tune to NSW-specific DTV channels from the Gold Coast? i.e. tune to live tv rather than the delayed QLD signals?

I live in Robina.

Cheers.

Do you have a UHF band 5 antenna pointed at Mt Tambourine?

ABQ (ABC Queensland ) is on channel 62 and move to channel 41

SBS (Queensland time feed) is on channel 36 going to 40

BTQ (7 Network Brisbane Program) 53 to 42

QTQ (9 Network Brisbane program) 59 to 45

TVQ (10 network Brisbane program) 56 to 44

NEN (Prime Northern NSW program) 65 to 46

NBN (NBN Northern NSW program) 68 to 47

NRN (Southern Cross NSW program) 43 to 48

The channel change will occur on 28th this month. Do a rescan after 5AM and the receiver will store channel 41 with the label of 2, 21, 22, 23, 24. Similarly SBS will be 3, BTQ will be 7, QTQ will be 9 TVQ will be 1, 10.., NEN will be 6 NBN will be 8 and NRN will be 5. Remember that 7Mate will be 60 and in NSW time, GEM 80, One 50.

I don't live in the Gold Coast, but when I was there, I remember that the NSW based channels had their schedules adjusted for Queensland time (i.e. AEST) on their transmitters serving the gold Coast. Is that still the case?

If so, then in order to watch these stations in daylight saving time, you would need to receive them from a transmitter serving NSW.

Possibilities include:

1) Murwillumbah

The transmitter site is Springbrook - the same location where the Gold Coast Southern Hinterland transmitters are located. However, that doesn't mean you will receive them. For a start, the transmitter power may be weaker towards the Gold Coast. Secondly, the polarity is vertical, as opposed to horizontal for the Gold Coast Southern Hinterland.

2) Richmond/Tweed

Polarity is horizontal

For both transmitters, the stations are on channel 29-33.

BTW: the stations from Mt. Tambourine are being simulcast on the new and old frequencies, so you can tune to the new ones right now if you plan to use that transmitter site.

Alan has it all totally wrong again.......I really wish you would check first before posting Alan

The new restack channels on the Gold Coast are up and operational now. The Gold Coast has been in a simulcast for the past three months that ends on the 28th of October.

NBN broadcasts in Queensland time on the Gold Coast. It has to be this way so that programs go to air at the correct times due to program classifications (you cant have programs with the wrong rating going to air at the wrong time).

I think you will find all regional broadcasters have specific program feeds for the Gold Coast.

Steveb,

I have seen these transmissions last year on the pre-restack during summer with the time difference.

I am aware that these additional transmitters are on air now, however I did not want dual signals to cause the LCNs starting at 350-358 being created by the receiver. This is confusing. You want the EPG which commonly shows networks in LCN order to put NBN next to Nine and not at the bottom requiring the screen to be rolled down. This could have been eliminated by manually tuning each of the channels which is time consuming. It would appear by the question that this viewer cannot see these regional channels at the moment.

The only reason for simulcasting is so that MATV system amplifiers can be retuned.

Obviously there is specific program feeds for regional networks than capital city networks so that local advertising can be inserted. In addition QTQ Brisbane feed to its Gold Coast transmitters is not off air because they have a Gold Coast news bulletin in prime time.

Assumptions are dangerous Steve
