The Ffestiniog transmitting station is a broadcasting and telecommunications facility located on the slopes of Mynydd Maentwrog about 3 kilometres (1.9 mi) south of the town of Llan Ffestiniog, in Gwynedd, Wales. It was originally built by the IBA, entering service in early 1969 acting as a BBC and ITV relay transmitter for the now-defunct 405-line VHF television system.
Specifications
[edit]The site has a self-standing 45 m (148 ft) lattice tower erected on land that is itself about 310 metres (1,020 ft) above sea level. The television broadcasts primarily cover the towns of Ffestiniog, Blaenau Ffestiniog and the Vale of Ffestiniog in general.
625-line colour TV came to the site in the late 1970s.
The 405-line VHF television service closed across the UK in 1985, but according to the BBC's and ITV's transmitter list[1] and the BBC's internal "Eng. Inf." magazine,[2] Ffestiniog's 405 line services were due to close early - in the third quarter of 1982.
Ffestiniog currently broadcasts digital television and analogue FM radio.
Services listed by frequency
[edit]Analogue television
[edit]28 February 1969 - Late 1970s
[edit]The start date is for ITV service from the site. It is not clear when the BBC service commenced. The transmitter was classed as a relay of Blaenplwyf about 40 miles (65 km) to the south (for BBC) and as a relay of Preseli about 120 kilometres (75 mi) to the south (for ITV). However, the line-of-sight to Preseli is obstructed about 6 miles (10 km) to the south of Ffestiniog, and it is likely that the signal feed was obtained by off-air reception of Arfon about 25 kilometres (16 mi) to the west, itself a repeater of Preseli.

[edit]Colour TV eventually arrived, with the site now additionally acting as a very indirect relay of Llanddona (about 30 kilometres (19 mi) to the north) for the 625-line services, receiving its signal off-air from Llandecwyn, itself receiving a signal off-air from Arfon, which received its signal off-air from Llanddona itself.

Being in Wales, Ffestiniog broadcast the S4C variant. 405-line television was discontinued (after a mere 13 years) at about the same time as this new service started up.
