The Nebo Relay Mast Built in the 1960s, initially to relay ITV signals from the Preseli mast in Pembrokeshire SN1026, the mast located on a 971 feet high hill is itself a 1000 ft high. Nowadays, it transmits signals for BBC1 (Wales), BBC2 (Wales), ITV and the Welsh language channel, S4C. It also relays independent radio, including Classic FM and the Caernarfon based bi-lingual Champion 103 FM pop station, but not BBC radio which is transmitted from Llanddona SH5880.
