Holywell Hill transmission site

This transmission site, located in County Donegal, Ireland, is owned and operated by 2RN (formerly RTÉ NL) . The transmitter mast is a self-supporting steel lattice tower 60m tall, with the site itself being 260m ASL, and just 50m from the border with Northern Ireland. The station was opened in 1981 to provide UHF television coverage to parts of County Donegal and Derry City and County. It originally carried the four Irish analogue channels, RTÉ One (Ch 23), RTÉ Two (Ch 26), TV3 (Ch 29), and TG4 (Ch 29), all horizontally polarised and at an effective radiated power of 20 kW. Digital terrestrial television (DTT) was first broadcast from the site in 2008, and all analogue television channels were eventually shut down on 24 October 2012
Today the Irish digital television service Saorview, and five national radio stations on FM, are broadcast from Holywell Hill to a large area of North West Ireland including Derry/Londonderry city. The transmitter also services a number of relay transmitters in County Donegal to help improve coverage in the difficult terrain.
