Thanks in advance!

I assume you have read my "Get the best reception" post at the start of this strand and read its links NSW and Indoor antennas.
If you are on the lower North Shore, too much signal can also be a problem.
Are you in an apartment block?
I have not tested the antenna you mention.
When you post next could you please mention the suburb you are in.

Yes I have read the best reception post & its links
I am in the inner west @ Five Dock
I'm not in an apartment block
Am I missing something in the other threads? Should I be scanning other freqencys? Does channel 9 broadcast on more than one frequency? Or am I right just sticking w/ scanning 191625 kHz?
Should I be looking @ getting an attenuator instead? I have NO experience w/ this sort of thing, so please bear with me

On the "Get the best reception" use the link to coverage area and see if you are in the coverage area for Kings Cross.
In either case you will probably need an external antenna.

7 uses VHF 6 @ 177.5 MHz
9 uses VHF 8 @ 191.625 MHz
10 uses VHF 11 @ 219.5 MHz
The only difference is that 7 & 10 broadcast from Atarmon, where as 9 brodcasts from Willougby
From my understanding (and I may be wrong) They broadcast analogue & digital on the same frequency? So why is it that I can get analogue 9 & not digital?

I have just checked reception at Concord and Leichhardt and all channels are working fine.
The coverage maps are indicative only and there are numerous things that can affect signals, especially when using an indoor antenna, such as the building itself, other buildings, trees, anything between your antenna and the transmitters, or even objects that are not directly in the signal path, but which signals bounce off... even people and furniture in the room!
It's possible you have too much signal. In that case, attenuators are required.
You need to have accurate signal measurements taken with a digital field strength meter, so you know exactly what the problem is, then a solution can be recommended.
Digital TV channels are not on the same frequencies as the analogue channels. (not in the same areas, anyway) Perhaps you are confusing this with both SD and HD digital signals being on the same frequency?
Apart from Artarmon and Willougby, ABC, SBS and D44 transmit from Gore Hill.
As alanh suggested, you could try the Kings Cross translators.
ABC... UHF 30 Hor 543.625 MHz
7........ UHF 48 Hor 669.500 MHz
9........ UHF 33 Hor 564.500 MHz
TEN.... UHF 45 Hor 648.500 MHz
SBS.... UHF 34 Hor 571.500 MHz
Note: There is no translator an Kings Cross for D44

I've solved the problem - I got the L4074 - & now ALL digital channels - so I guess you can add that model antenna to the list...
Yeah I tried scanning for channel 33 @ 564.500 MHz & I got nothing, so I figured I'd give the antenna a go - thankfully It paid off - I might mount it outside tomorrow so I have a clear line of site w/ less interference from the things in this room.
Thanks again for you time

Which channels did you end up with... the main VHF channels, or the Kings Cross UHF translators?
Posted 19 January 2008 - 04:38 PM
there's your problem, you were fooled by Dick Smith Staff into getting that one, $2 Rabbit Ears tend to work better than these.
EDIT: ok, in this case it may have worked properly, but it usually doesn't work "as well" as $2 rabbit ears.

True it is pretty expensive, & yes I was getting good reception w/ the el cheapo rabbit ears, but no channel 9 was a real annoyance... I am thinking that maybe it is just b/c of the 6M quadshield cable I picked up that has allowed me to pick up channel 9 (I just tested it with the rabbit ears and it works). However, I can mount this antenna outside, which I will proberly do @ some point...
So yeah, it may be that the L4074 is a waste (Seems like it ) However, it works - so maybe its a better idea for people in my situation to just get the cable and move the rabbit ears around (if you don't mind the aesthetics )

Set the TV up yesterday, and it auto-tuned all channels except for Channel 9. The first time, it was missing both Ch7 and Ch9, but after re-tuning, Ch7 is fine now. Re-tuning still didn't get Ch9 again. I can get Ch9 on analogue but it's clearly snowy in picture. Only message on the TV is weak/no signal, which doesn't really help.
When I get home, I will try re-tuning manually to 191625 MHz but am pretty sure we tried the manual tuning to that default frequency last night with no success.
Anyone have a suggestion?

Indoor antennas in your situation are very poor.
You need a split of the outdoor antenna. It would be best to replace the antenna for one designed for digital ie one designed for channels 6 - 36, or band 3 & 4.
See the first post in this strand for more details.

Analog reception was not bad, but have had Fox cable on for past 15yrs and have not worried about free to air for some time, possibly antenna is to old?
Posted 09 February 2009 - 09:57 PM
I have a feeling this is the beginning of a long line of replacements for the cabling in my place?
Just saw a post about multi connections "F" type splitter, my splitter is of the old plastic cover type for coax cable connections.
So i think i might have to do some updating across the board. Ah well so much for a free weekend?
Thank you for the advice will keep in touch.

This site has two buildings, each with identical antennas. Ch9 has only disappeared on one of them. Retuning hasn't worked. Maybe it will just re-appear in a few weeks :-)

I wonder if it's the major building work at Hurstville [the old Containers Ltd redevelopment at Allawah/Hurstville for example] impacting suburbs south of there? I note a Penshurst issue also on this forum and we're south of Penshurst.

It sounds as if the new building is blocking your signal. If cranes are being used they will vary the signal as will some metals being lifted. After the cranes are gone, there will be no improvements.
You may perhaps have a clear view to the Elan Building in Kings Cross. If so you need a band 4+ Yagi antenna and perhaps a UHF masthead amplifier.
The best thing to do is to wait until the outside of the building is complete and then get an antenna installer to measure the signals for the error rates to select the best transmitter site option and appriate antenna.

1)- We live in a Hurstville, Sydney apartment with no roof antenna available. The unit is right on the road though, on ground level, so I donít think reception could be such a big problem?
2)- Using the L4016 from DSE we can scan every channel except any of those provided by Channel 9 (TCN).
3)- I have tried every conceivable antenna direction and height and adjustment of the amplifier/gain all to no avail!
I dont understand how to read the documents available on this site and I have no idea, so can I ask:
1)- How do I direct my antenna to the Channel 9 broadcast tower. Where is it? Which suburb?
2)- If Channel 9 isnít showing but the rest of the channels are, is it due to the fact, and I read this here somewhere, that the signal is actually too strong? If so, how do I 'dampen' the signal if even lowering the amplifier doesnít work?
3)- On my antenna is the big grey middle section for UHF and the two rabbit ears for VHF? Should I focus on one of those doing something special?
4)- What is the frequency of the Channel 9 channels (especially GO!)? Are they on UHF or VHF? I seem to have read that they are on both. Would manually tuning the channels in work? Do I tune in just one frequency or do I do one for each of the Channel 9 channels?
5)- Can anyone recommend an antenna in my situation?
I am so sorry for all the questions!
