Mynydd Pencarreg transmitting station

Transmitter in Carmarthenshire, Wales


The Mynydd Pencarreg transmitting station is a broadcasting and telecommunications facility located on high ground about 10 kilometres (6.2 mi) south of Lampeter, in Ceredigion, Wales. The site has a guyed 99 m (325 ft) lattice mast erected on land that is itself about 410 m (1,345 ft) above sea level. It was originally built by the GPO as a telecommunications relay, and (amongst other things) was responsible for handling the microwave feed carrying the now-defunct 405-line VHF BBC television service to the television transmitter at Blaenplwyf about 35 kilometres (22 mi) to the northwest near Aberystwyth. Despite this, Mynydd Pencarreg was never a 405-line TV broadcast site.

Broadcast UHF television was added to the site in early 1981,[1] launching with just the three programme services that were active at the time. S4C was added in 1982 when it launched.

Currently, the transmitter provides DVB-T digital television to the Lampeter area, along with FM radio.
