Hello all,

Plz do not laugh if my question seems too simple to answer, first time on this forum.
I have a LCD TV with dual tuners, analogue and digital DVBt tuner. I have got a VHF antenna installed which gives a crap reception. Due to the digital tuner in my LCD TV I only get 4 channels (1 2 3 C4) and even they are not 100% crystal clear.
I have a cheap 21in flat screen TV in my bedroom and no outdoor antenna connection, I use a wire hanger I get 6 - 7 channels and depending how I move the hanger the picture is very good quality, to keep my story short I must be in good reception area if I can get the channels on my bedroom TV without external antenna, where my big LCD TV is not doing what I purhased it to do.

The main question is what do I need to get free view digital coverage for my LCD TV, a couple of people have told me that because I have DVBt tuner built in I only need a cheap satelitte dish connected directly to my TV without the digital Freeview receiver. If that is true, what kind of LNB do I need? and how can I split the signal to my second TV.
One other person told me to just get a UHF antenna and I should get all the digital channels.

please help and advice correctly

Firstly there are no DVB-T broadcasts in NZ at present so you will be tuning in analogue broadcasts, not DVB-T. A DVB-T trial had been occuring in Auckland for the past 2 years or so but this stopped a while back.

To get Freeview you will need a DVB-S set top box (1 per TV) and a satellite dish, DVB-T transmissions will start in Auckland and Wellington in February next year but will use MPEG4 so unless your TV supports this the DVB-T won't work anyway. This has been one of the reasons why no manufacturers have been bringing TV sets with DVB-T tuners into NZ because many would never work.

Where exactly are you located? All you possible need is just a good external aerial and splitter to run both TV's.

I am in South Aucland on a flat land, as explained in my original question that I have a good reception in my bedroom and even get prime without an antenna.
So what I understand from your post is that my DVB-t digital tuner has no use in NZ for now?
So shall I just get 93 element uhf antenna with duplex vhf function to get the few channels on offer?
would this give perfect picture?

Here is some spec links for my TV

The DVB-T tuner in the Acer will NOT ever work in NZ as it is an mpeg2 tuner. The Freeview UHF DVB-T terrestrial service to be introduced next February will use mpeg4 rather than mpeg2. You will need a set top box. The Freeview DVB-S mpeg2 satellite service to start in 6 weeks or so will require a set top box, 65 cm dish with a 10.750 GHz LNB. I would choose the satellite option unless you like waiting. FTA DVB-S mpeg2 decoders and even dishes for the satellite service are available off Trade Me - choose a box with component out. DVB-T mpeg4 decoders are NOT available because NZ will be the first country with a FTA DVB-T mpeg4 service. Some channels on the DVB-T mpeg4 service may be high definition 1280 x 720p or 1920 x 1080i. DVB-S mpeg2 service will be 16:9 ratio 720 x 576i only.

Most analog signal will look bad on any 37" LCD. If the antenna connected to it is VHF (44 to 51 MHz + 54 to 68 MHz + 174 to 230 MHz) then you can't really expect gain in the UHF part (518 to 806 MHz) of the spectrum. DVB-T transmissions are susceptible to impulse noise so any cabling should use RG-6 quad shielded coax with F type connectors and a reasonable gain UHF antenna. You may even find that "rabbit ears" will work (given your wire coat hanger experiments) with the DVB-T service.

Do you mean will the aerial be useless or will  the card be useless? The aerial will work OK but odds are the card will be useless, it's unlikey it will support MPEG4.

Freeview have done a smart thing by switching off the DVB-T transmissions for a year before they restart, it'll stop people selling STB's and PC cards in NZ that won't work (not that it's stopped companies like DSE selling stuff though).

with a computer dvb-t card your only problem (i think) would be with software or if the card has a hardware encoder. My hvr-900 hybrid apparently works with mpeg-4 and also worked well with the mpeg-2 trial. Also quite alot of the dvb-t tuners for computers may be able to be used with mheg-5 seeing as its software stopping support and not hardware...

Having a built in DVBt tuner is pretty cool. If only it was currently being broadcasted in NZ. :p




Can't beat the burble of that American V8. Ohh yea!
