Two companies, TWW Ltd. and Wales (West & North) Ltd. (WWN), provide programmes for the Authority to broadcast to Welsh viewers. In addition to its responsibilities in South Wales, TWW also covers a wide area in the West of England; it provides programmes for the ITA’s transmitter at St. Hilary, opened in 1958, serving a population of 3.3 million. The technical difficulties of the area covered by Wales (West & North) Ltd. are indicated by the fact that three transmitters are needed in South-West, North-West and North-East Wales to broadcast its programmes to a population of about 1 million. These transmitters opened during 1962-63. ITA Regional Officer: L. J. Evans, Arlbee House, Greyfriars Place, Greyfriars Road, Cardiff. Cardiff 28759.

Southern England: Southern Television Ltd. provides programmes for Southern England from Kent to Dorset, an area which is not easily defined geographically or technically. The ITA’s transmitters at Chillerton Down on the Isle of Wight (opened in 1958) and at Dover (opened in 196O) serve a population of 4.3 million. ITA Regional Officer: Cmdr. G. W. Alcock, O.B.E., R.N. (Rtd.), 3o Portland Street, Southampton. Southampton 29115.

North-East England and Border Regions: The North-East of England, with programmes provided by Tyne Tees Television Ltd., is geographically, technically and socially well defined, consisting basically of the main part of the counties of Northumberland, Durham and the North Riding of Yorkshire. A population of 2.7 million is served from the ITAs transmitter at Burnhope, opened in 1959. Border Television Ltd. serves two nationalities as its area straddles the Anglo-Scottish border, its programmes being broadcast by one transmitter at Caldbeck and another at Selkirk in Scotland (opened 1961) to a population of nearly half a million. ITA Regional Officer: R. J. F. Larimer 32-4 Mosley Street, Newcastle-upon-Tyne. Newcastle 61-0148.

East Anglia: This was the first predominantly rural area in which the Independent Television Authority appointed a programme contractor, Anglia Television Ltd. This area is again both historically and geographically well defined. The topography of the area necessitated the first 1,000 ft. mast erected for the Authority, to serve a population of 2½ million. Programme operation commenced in 1959. ITA Regional Officer: Major General D. A. L. Wade, C.B., O.B.E., M.C., Century Insurance Building, 24 Castle Meadow, Norwich. Norwich 23533.

The Province of Northern Ireland is served by two transmitters. The major one near the principal centre of population, the Belfast area, opened in 1959. The second, at Strabane in the west of the Province, opened early in 1963. Programmes are provided by Ulster Television Ltd. The population served is 1.4 million. ITA Regional Officer: W. H. Wilson, 5 Donegall Square South, Belfast. Belfast 3o818.

South-West England and the Channel Islands: Another geographically well-defined area is the South-West of England, consisting of the peninsula of Cornwall, Devon and parts of Somerset and Dorset.

Black Mountain (Channel 9) and Strabane (Channel 8)

Company: Ulster Television

A large part of Northern Ireland was provided with an Independent Television service in the Autumn of 1959 by the construction of the Black Mountain station near Belfast, close to the BBC’s existing Band I station at Divis. However, West Ulster, which includes the districts of Londonderry and Enniskillen, could not be covered by this station and, clearly, at least one additional station was needed.

The Black Mountain station overlooks Belfast and is 987 ft. above sea level. A 750 ft. mast, the highest permitted by the Ministry of Transport and Civil Aviation due to the proximity of the airport, was erected. It supports a moderately-directional aerial radiating about 100 kW to both the north-west and the south-west, 7o kW to the west and 20 kW to the east. This power-radiation pattern ensures the optimum coverage of the area whilst avoiding harmful interference to the service areas of other stations using Channel 9, notably Winter Hill.

A study of the topography of West Ulster revealed that the unserved area could economically be covered by a single station if a high site near Strabane could be obtained. A site 900 ft. above sea level was found four miles south-east of Strabane and here a station using a 1,000 ft. mast was constructed.

It has a highly-directional aerial radiating about 9o kW in two main lobes to the north and to the south. 10 kW only is radiated to the east and west, but this suffices to cover the areas not served by the Black Mountain transmitter and, at the same time, prevents unnecessary radiation into the territory of the Irish Republic to the west.

The Black Mountain station went into service on 31st October 1959. Strabane began programme transmission during February 1963.
