This site is home to one of RTÉ's original five main television transmitters, coming on air in 1963 with a 625-line VHF service for the Southwest of Ireland, namely counties Cork, Kerry and Limerick. Today it is owned and operated by 2RN a wholly owned subsidiary of RTÉ. In 2009 in preparation for the transmission of digital terrestrial television (DTT), a new mast was constructed at Mullaghanish with a height of 225m and the original 170m mast was removed. Analogue television transmissions from this site ended on 24 October 2012, and the national DTT service, Saorview, is now broadcast from Mullaghanish at an ERP of 200 kW, removing the title of most powerful television transmitter in Ireland from Cairn Hill and awarding it to Mullaghanish.
As well as digital television, six national FM radio services are broadcast from the site, all using vertical polarisation. Local station, Radio Kerry, is broadcast from a directional antenna pointing west, into its target service area of County Kerry, and Newstalk is broadcast in mono.
