- Arranmore Island transmitter
The Arranmore Island transmitter is a relay station used by
RTÉ Networks Limited andHighland Radio to provide coverage toArranmore Island ,Ireland , and much ofThe 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 construction of the RTÉ mast in the 1990s was controversial for a number of reasons, one of them being that the allocated television frequencies (which had been reserved and known for some time) interfered with then-unlicenced relay broadcasts of British television channels in parts of Count Donegal. During construction, the partially constructed mast was felled, with the culprit(s) being unknown. There were also robberies of equipment from the construction site.
A 1kW transmitter, on 104.0 MHz, has been proposed for the
i102-104 radio station which launched in February 2008. BothO2 Ireland andVodafone Ireland have transmission stations on the RTÉ mast.Three television stations and 6 radio services are carried from the site.
