Hi we have just purchased a new TV with built in Freeview but the thing is we can't receive those channels as mentioned above.

I had a look at this topic here http://www.geekzone.co.nz/forums.asp?forumid=83&topicid=70733 which describes turning the LNB but we don't have a dish just the antennae so is there anyway to receive the channels with just the antennae?

Thanks in advance

A few quick questions...
What type of TV?
What sort of aerial is on the roof (a picture would be great)?
What was your reception like on Prime previous to purchasing the new TV?

Sounds like you have built in Freeview HD which doesn't go off a dish.

You can't receive TVNZ channels but can receive tv 3 and c4? In that case, your UHF aerial needs tuning to the tvnz signal. May be hlls/trees distorting the signal to tvnz base.

TVs with built in Freeview will have a Freeview HD tuner.
That doesnt use a satellite dish.
Presumably you have plugged it into your current roof aerial.
How old is your rood aerial?
It has to have UHF (which are the smaller rods). It could be a combo UHF/VHF (likley) which is like a small UHF aerial and larger VHF aerial combined.

If you got Prime nice and clear before then you probably have an ok UHF aerial and maybe need to reposition it a little.
Those channels all go out on the same frequency so its not surprising that you cant get all of them but might get the others.

Key question.. where are you located? Use this page to find out if you have Freeview|HD coverage in your location
http://www.freeviewnz.tv/get_freeview

However as above if you are getting TV3 and C4 then most likely your existing aerial just needs a tune.

@Dunnersfella

What type of TV?
Just a plasma HDTV from panasonic

What sort of aerial is on the roof (a picture would be great)?
Hmm it's just a very regular aerial sorry can't take a picture atm, looks a lot like this though http://www.summitsource.com/images/products/ANW055.jpg I'll try provide a picture tomorrow

What was your reception like on Prime previous to purchasing the new TV?
Reception was a bit fuzzy for Prime

@robig63

How old is your rood aerial?
Not too sure probably over 6 years old?

@Nety

Key question.. where are you located?
I used the coverage and it said and it said very likely for both UHF aerial and Satellite

Image is of a band 2 VHF FM radio antenna, 88 to 108 MHz. If you have an antenna that looks similar it will be VHF low band only maybe, 54 to 68 MHz. Freeview HD is UHF, totally different band, 518 to 806 MHz.

You need a UHF aerial as the picture of your aerial is a VHF type thats why you have free view reception issues. Check out this link...

A VHF aerial does receive UHF, just not nearly as well as a UHF aerial. Often old VHF aerials lack line of sight to the transmitter - if this is the case it might only need shifting instead of replacing.

I would just replace. A new UHF aerial is not that expensive and will do the job properly.

Soooo I take it that the best solution would be just to get a new aerial?

That seems relatively reasonable but say I do buy an aerial how do you like install it?.. Do I need a technician or can I just D.I.Y this badboy with some online instructions?

Edit: What about a dish or unnecessary?

Many thanks!

Ahh Yeah!

If you are a practical person should be easy to D.I.Y.

http://www.freeviewshop.co.nz/element-aerial-freeview-p-457.html

Site has install instructions for product.

Should be able to remove old aerial connect new UHF one no problem. The fact you get some of the freeviewHD channels already seems to indicate signal is fairly strong where you are. Look at the next door roof's for aerial direction(most likely same direction as old aerial) and polarisation .

Edit: What about a dish or unnecessary?

You don't need a dish.

If you are in Wellington, contact Cyril7 here on Geekzone. If you are outside Wellington, I think there's a list of installers on Freeview's own website.
