Pontardawe television relay station

Transmitter sites in WalesWenvoe UHF 625-line Transmitter Group

The Pontardawe television relay station was originally built in 1974/1975 as a relay for UHF analogue television. It consists of a 45 m self-supporting lattice mast standing on a hillside which is itself about 160 m above sea level (about 100 m above the town). Currently, the transmitters cater for most of the digital terrestrial TV subscribers in the towns of Pontardawe and Alltwen and in the nearby villages of that section of the Tawe valley. The transmission station is owned and operated by Arqiva. When it was built, Pontardawe transmitter re-radiated a signal received off-air from Kilvey Hill about 12 km to the southwest. However, sometime after the Alltwen relay was built on the opposite side of the valley, the Pontardawe mast was reassigned to relay its signal instead. Both sites have line-of-sight to Kilvey Hill, but the direct signal to the Pontardawe site does have a close encounter with a wooded hillside 2 km away which severely intrudes into the signal's First Fresnel Region. Alltwen's line-of-sight is unobstructed. When it came, the digital switchover process for Pontardawe duplicated the timing at the parent station, with the first stage taking place on Wednesday 12 August 2009 and the second stage was completed on Wednesday 9 September 2009, with the Kilvey Hill transmitter-group becoming the first in Wales to complete digital switchover. After the switchover process, analogue channels had ceased broadcasting permanently and the Freeview digital TV services were radiated at an ERP of 25 W each.
