Transmitter
The Mount Leinster transmitter is owned and operated by RTÉ NL and at 796m ASL it is the highest transmission site in Ireland . It was one of the original five main Telefís Éireann television transmitters, opening on the 12th June 1963 with a 625-line service on Channel F. VHF FM radio transmission was added in 1966, with UHF television starting in 1996. The original mast was replaced in 2010 with a taller one of 130 m in preparation for DTT transmission. Today the station provides the Irish digital television service Saorview to a large area of South East Ireland, and the transmissions can also be received on the West coast of Wales.
