Cairn Hill Transmission Site
The Cairn Hill transmission site is located on a 277 metre hill ( Carn Clonhugh) at Dernacross in County Longford that lies 10 km north east of Longford town. Cairn Hill was the first of two new UHF television transmission sites to be opened in Ireland by RTÉ in 1978, the other being Three Rock in County Dublin. This was to facilitate the introduction of the second television channel RTÉ 2 on UHF, as all the available VHF frequencies were in use by existing transmitters in Ireland. The site was located to cover an area of poor reception in the Irish midlands, and when it opened it was the most powerful television transmitter in all of Ireland, with an Effective Radiated Power (ERP) of 800 kW. In later years another two television channels were added, TG4 and TV3. Digital terrestrial television (DTT) broadcasts began from Cairn Hill in February 2009, with analogue television services subsequently ending nationally on 24 October 2012. Today the transmission site, own ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cairn Hill Distant
A cairn is a man-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word ''cairn'' comes from the gd, càrn (plural ). Cairns have been and are used for a broad variety of purposes. In prehistoric times, they were raised as markers, as memorials and as burial monuments (some of which Chambered cairn, contained chambers). In modern times, cairns are often raised as landmarks, especially to mark the summits of mountains. Cairns are also used as Trail blazing, trail markers. They vary in size from small stone markers to entire artificial hills, and in complexity from loose conical rock piles to elaborate megalithic structures. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. A variant is the inuksuk (plural inuksuit), used by the Inuit and other peoples of the Arctic region of North America. History Europe The building of cairns for various purposes goes back into prehi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irish Midlands
The Midland Region (coded IE063) is a NUTS Level III statistical region of Ireland. It consists of the territory of the counties of Laois, Offaly, Westmeath and Longford. The Midland Region spans 6,524 km2, 9.5% of the total area of the state and according to the 2016 census has a population of 292,301. Before 2014, the region was governed by the Midlands Regional Authority. The Authority was abolished in 2014. Midland now exists as a strategic planning area within the Eastern and Midland Region. The NUTS regions are used for statistical reporting to Eurostat, while the Regional Assemblies are responsible for planning at a local government level. The Midland Region is also a tourist destination due to its natural environment which includes lakes, waterways and canals, as well as a history, heritage and culture which dates from early Christian times.

Transmitter Sites In Ireland
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters, ev ...

Broadcast Relay Station
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater (two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station. It expands the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. However, depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Broadcast translators In its simplest form, ...

IRadio
iRadio is a music-driven youth radio station broadcast in the Border, West, Mid-East and Midland regions of Ireland. The station is one of four music-driven youth stations that were licensed by the Broadcasting Authority of Ireland to challenge the current duopoly in the 15-34 age bracket for those outside Dublin by national stations RTÉ 2FM and Today FM. The station, based in Athlone and broadcasting to an average listenership of 227,000, was created by the merger of i102-104FM and i105-107FM on 4 July 2011. The combined 15-county franchise was awarded a new ten-year license in 2019. Notable people *Claire O'Callaghan, news and sports journalist and radio presenter See also * Radio in Ireland Licensed radio broadcasting in Ireland is one element of the wider media of Ireland, with 85% of the population listening to a licensed radio broadcasting service on any given day.

RTÉ Radio 1
RTÉ Radio 1 ( ga, RTÉ Raidió 1) is an Irish national radio station owned and operated by RTÉ and is the direct descendant of Dublin radio station 2RN, which began broadcasting on a regular basis on 1 January 1926. The total budget for the station in 2010 was €18.4 million. It is the most-listened-to radio station in Ireland. History The Department of Posts and Telegraphs opened 2RN, the first Irish radio station, on 1 January 1926. Station 6CK, a Cork relay of 2RN, joined the Dublin station in 1927, and a high-power transmitter at Athlone in County Westmeath opened in 1932. From the latter date the three stations became known as Radio Athlone, later being renamed Radio Éireann ("Irish Radio"/"Radio of Ireland") in 1937. Like most small European national stations at that time, Radio Éireann attempted to satisfy all tastes on a single channel. It broadcast a mixed schedule of light entertainment and serious drama, Irish language programming, and talks. Radio Éireann ...

2RN (RTÉ Networks)
2RN is the trading name of RTÉ Transmission Network DAC, a wholly owned subsidiary of Raidió Teilifís Éireann, formerly trading as RTÉNL, which runs Ireland's principal digital terrestrial television and radio broadcast networks. In December 2002 it became an incorporated company and subsidiary of RTÉ, it was previously a division within RTÉ. It operates 12 main TV and radio transmitter sites and many smaller relays and transposers, which carry television and/or radio. It also provides site hosting for mobile telephone operators, the emergency services, wireless broadband and other private mobile communications service providers.

Digital Terrestrial Television
Digital terrestrial television (DTTV or DTT, or DTTB with "broadcasting") is a technology for terrestrial television in which land-based (terrestrial) television stations broadcast television content by radio waves to televisions in consumers' residences in a digital format. DTTV is a major technological advance over the previous analog television, and has largely replaced analog which had been in common use since the middle of the 20th century. Test broadcasts began in 1998 with the changeover to DTTV (aka Analog Switchoff (ASO), or Digital Switchover (DSO)) beginning in 2006 and is now complete in many countries. The advantages of ''digital'' terrestrial television are similar to those obtained by digitising platforms such as cable TV, satellite, and telecommunications: more efficient use of limited radio spectrum bandwidth, provision of more television channels than analog, better quality images, and potentially lower operating costs for broadcasters (after the initial up ...

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Channel Frequencies
The following tables show the frequencies assigned to broadcast television channels in various regions of the world, along with the ITU letter designator for the system used. The frequencies shown are for the analogue video and audio carriers. The channel itself occupies several megahertz of bandwidth. For example, North American channel 1 occupies the spectrum from 44 to 50 MHz. See Broadcast television systems for a table of signal characteristics, including bandwidth, by ITU letter designator. VHF Americas (most countries), South Korea, Taiwan, Burma (Myanmar) and the Philippines During World War II, the frequencies originally assigned as channels 13 to 18 were appropriated by the U.S. military, which still uses them to this day. It was also decided to move the allocation for FM radio from the 42-50 MHz band to a larger 88-106 MHz band (later extended to the current 88-108 MHz FM band). This required a reassignment of the VHF channels to the plan curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County Longford
County Longford ( gle, Contae an Longfoirt) is a county in Ireland. It is in the province of Leinster. It is named after the town of Longford. Longford County Council is the local authority for the county. The population of the county was 46,634 at the 2022 census. The county is based on the historic Gaelic territory of Annaly (''Anghaile''), formerly known as Teffia (''Teathbha''). Geography Most of Longford lies in the basin of the River Shannon with Lough Ree forming much of the county's western boundary. The north-eastern part of the county, however, drains towards the River Erne and Lough Gowna. Lakeland, bogland, pastureland, and wetland typify Longford's generally low-lying landscapes: the highest point of the county is in the north-west - Carn Clonhugh (also known as Cairn Hill or Corn Hill) between Drumlish and Ballinalee in the parish of Killoe, at . Cairn Hill is the site of a television transmitter broadcasting to much of the Irish midlands. In the list o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
