Terrestrial television is a type of television broadcasting in which the television signal is transmitted by radio waves from the terrestrial (Earth-based) transmitter of a television station to a TV receiver having an antenna. The term terrestrial is more common in Europe and Latin America, while in the United States it is called broadcast or over-the-air television (OTA). The term "terrestrial" is used to distinguish this type from the newer technologies of satellite television, in which the television signal is transmitted to the receiver from an overhead satellite; cable television, in which the signal is carried to the receiver through a cable; and Internet Protocol television, in which the signal is received over an Internet stream or on a network utilizing the Internet Protocol. Terrestrial television stations broadcast on television channels with frequencies between about 52 and 600 MHz in the VHF and UHF bands. Since radio waves in these bands travel by line of sight, reception is generally limited by the visual horizon to distances of 64–97 kilometres (40–60 mi), although under better conditions and with tropospheric ducting, signals can sometimes be received hundreds of kilometers distant.
Television broadcasting in Greece began in 1966 and this was preceded in 1951 by statute 1963 permitting television broadcasting.
Digital terrestrial television 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 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.
The Crystal Palace transmitting station, officially known as Arqiva Crystal Palace, is a broadcasting and telecommunications site in the Crystal Palace area of the London Borough of Bromley, England. It is located on the site of the former television station and transmitter, operated by John Logie Baird, from 1933.
The Moel-y-Parc transmitting station is situated on Moel y Parc, a hill in north-east Wales at the northern end of the Clwydian range, close to the town of Caerwys and several miles (kilometres) north-east of Denbigh. It was built in 1962/1963 by the IBA to bring 405-line VHF ITV television to North Wales and it has been on the air since 1963. Its original height of 229 metres (751 ft) made it the tallest structure in North Wales and it stands on land that is itself about 335 metres (1,099 ft) above sea level. In 1965, VHF television transmissions from the BBC commenced from the site.
The Llanddona transmitting station ; Welsh pronunciation) is a broadcasting and telecommunications facility, situated at Llanddona, near Beaumaris, on the isle of Anglesey, Wales.

The station lost both its community franchise and the battle to remain on the air on 8 December 2015 and ceased transmission on 20 December 2015 after almost ten years on the air. The station was not replaced.
Digital terrestrial television in Australia commenced on 1 January 2001 in Sydney, Melbourne, Brisbane, Adelaide and Perth using DVB-T standards. The phase out of analogue PAL transmissions began on 30 June 2010 and was completed by 10 December 2013.

The Haverfordwest transmitting station is a broadcasting and telecommunications facility located at Woodstock about 13 km (8 mi) to the north east of the town of Haverfordwest, in Pembrokeshire, Wales. It was originally built by the BBC, entering service in early 1964 acting as a main transmitter for the 405-line VHF television system, and as a repeater for Band 2 VHF FM radio received off-air from Blaenplwyf transmitting station. It is now owned and operated by Arqiva.
The digital television transition, also called the digital switchover (DSO), the analog switch-off (ASO), the digital migration, or the analog shutdown, is the process in which older analog television broadcasting technology is converted to and replaced by digital television. Conducted by individual nations on different schedules, this primarily involves the conversion of analog terrestrial television broadcasting infrastructure to digital terrestrial (DTT), a major benefit being extra frequencies on the radio spectrum and lower broadcasting costs, as well as improved viewing qualities for consumers.
The digital transition in the United States is the switchover from analog to exclusively digital broadcasting of terrestrial television programming. According to David Rehr, then president and CEO of the National Association of Broadcasters, this transition represented "the most significant advancement of television technology since color TV was introduced." For full-power TV stations, the transition went into effect on June 12, 2009, with stations ending regular programming on their analog signals no later than 11:59 p.m. local time that day.

The 45 metre-high (150 ft-high) mast is situated at an elevation of 65.5 metres (215 ft). Thus, the top of the mast has an overall height of 110.5 metres (363 ft) above sea level. Construction of the mast was completed in 1980. As of 2009, the TV transmitter serves approximately 45,000 homes.
The Alltwen television relay station is sited on a hill to the southwest of Pontardawe in the Swansea Valley, at least a kilometre away from the village of Alltwen from which it takes its name. It was originally built in the late 1980s as a fill-in relay for UHF analogue colour television. It consists of a 17 m self-supporting lattice mast standing on Craig Glyn Meirch, a hillside which is itself about 140 m above sea level. The transmitters are beamed northwards and eastwards to cater for those digital terrestrial TV subscribers in the towns of Pontardawe and Alltwen who for reasons of geography can't get a signal from the much bigger and more powerful Pontardawe transmitter. The Alltwen transmission station is owned and operated by Arqiva.
The Mynydd Emroch television relay station is sited on the eponymous hill to the east of Port Talbot. It was originally built in the 1970s as a fill-in relay for UHF analogue television.

The digital television transition in Japan (アナログ放送終了) was the mandatory switchover from analog to digital terrestrial television broadcasting that began in 2008 and continued through early 2012. The switchover itself took place between 24 July 2011 and 31 March 2012, and involved television stations across all five major commercial networks, the entire network of NHK's broadcast transmitters, and television stations that are part of the JAITS group. Japan was the first country in eastern Asia to cease broadcasting television signals in analog.
