Arranmore Island transmitter

From Wikipedia, the free encyclopedia

The Arranmore Island transmitter is a relay station used by RTÉ Networks Limited and Highland Radio to provide coverage to Arranmore Island, Ireland, and much of The Rosses, which are shielded by mountains from the main transmissions. Two towers exist, the smaller of which belongs to Highland, and the significantly larger to RTÉ Networks. The EIRP of the stations transmitted by RTÉ Networks is amongst the highest of any relay station. The site is 125 m above sea level, with the RTÉ antenna standing at 45 metres.

The station has been used in the licence application of i105, who received a licence to broadcast to the north-west of Ireland in 2006 but have yet to begin broadcasting. A 500W transmitter on the RTENL site has been proposed.

Three television stations and 6 radio services are carried from the site.
