Mynydd Pencarreg transmitting station


The Mynydd Pencarreg transmitting station is a broadcasting and telecommunications facility located on high ground about south of Lampeter, in Ceredigion, Wales. The site has a guyed lattice mast erected on land that is itself about above sea level. It was originally built by the GPO as a telecommunications relay, and was responsible for handling the microwave feed carrying the now-defunct 405-line VHF BBC television service to the television transmitter at Blaenplwyf about 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, 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.
