Hi, our family has a Sanyo LCD32XZ11 TV with built-in FreeView. Since the digital TV switch over, we've been able to receive some channels but not others. We can't receive TV 1, 2, 3, C4, Al Jazeera and a few others that I can't remember. But we can receive Prime, Maori TV, TrackSide, Choice, Chinese TV etc.

We're not sure if the antenna we currently have is an UHF aerial, since it's been here since we moved in, about 10 years ago. I've attached a picture. We live in Manurewa in South Auckland.

My question is, do we need to buy a new UHF antenna? Or should the current one be able to work, maybe if we just adjust the position slightly?

I'd appreciate any advice you might have, thanks.

It's a UHF antenna, but it is very likely the signal is not quite strong enough. This could be the antenna is not big enough, has moved out of alignment, or there is a corroded or bad cable joint somewhere. A common problem with older installations is the cable soaks up moisture and decays internally.

It is indeed a UHF antenna. If it's been there 10yrs or more though then it most likely needs replacing due to corrosion and also new run of co-ax would be a good idea too.

The type of UHF aerial you have is the type Sky used to use in the 1990s before they went to a satellite service. For Freeview UHF terrestrial you need a higher gain aerial such as the 21-element Aerial for Freeview HD which is available from The Freeviewshop or Dick Smiths .   When nistalling it , take the opportunity to check the cabling and all connections or get a professional installer to do it for you,

Hi RunningMan, B1GGLZ and peterds, thank you all for your answers. I did think that the aerial might be too old to receive all the FreeView channels. It's good to have confirmations though.
