4G Freeview retunes hit Welsh Wenvoe and Kilvey Hill relay transmitters

Thousands of Freeview homes across south Wales have to retune today when the Wenvoe and Kilvey Hill transmitter relays shift frequencies to avoid 4G mobile broadband interference. 

No-one should need a new Freeview aerial, and all Freeview HD products should automatically retune, along with most post-2010 Freeview TVs and boxes.

The retunes are part of the 4G Freeview Fail, where UHF channels 61 and 62 in the 800MHz range must be cleared to make way for new mobile broadband services.

Read more about the 4G Freeview FailHomes using the Wenvoe and Kilvey main transmitters won’t need to retune, but the changes will affect many of their relay transmitters, used to reach the valleys of south Wales.

Some homes may also experience a brief loss of signal as engineers adjust the relay, but it won’t be re-tuned – on-screen messages will have explained who is affected.

The changes also affect BT Vision, TopUp TV and YouView products, but have no effect on Sky, Freesat and Virgin Media signals.


The Wenvoe relays which will retune are: 

Abercynon, Abergavenny, Blaina, Brecon, Dowlais, Ebbw Vale, Fernhill, Gellifendigaid, Llangeinor, Llanhilleth, Machen Upper, Monmouth, Mynydd Bach, Pennar, Porth, Risca, South Maesteg, South Tredegar, Taffs Well, Ton Pentre, Tonypandy, Tonyrefail, Trefechan , Tynewydd, Van Terrace, and Ynysowen.

The Kilvey Hill retunes will affect these relays:

Alltwen, Briton Ferry, Burry Port, Cilfrew, Craig Cefn Parc, Efail Fach, and Mynydd Emroch.
