# Angus transmitting station

The Angus transmitting station is a broadcasting and telecommunications facility, situated approximately five miles due north of Dundee, between the villages of Charleston and Tealing, Scotland (grid reference NO394407). It includes a guyed steel lattice mast which is 229.5 metres (753 ft) in height. Mounted at the top are the UHF television antennas, contained within a GRP shroud. These antennas have an average height above Ordnance Datum of 547 metres (1,795 ft). It is owned and operated by Arqiva.

## History

It was constructed in 1965 by the ITA, having been chosen as a suitable site for high power colour UHF transmissions.
The construction contract was given to J. L. Eve Construction in April 1963, to be built at Harecairn by early 1964, for the Tayside area, but not Dundee, which had a separate relay station.
The relay station was built by Laird Brothers, of Forfar, to open in the summer of 1964.
The site would open in October 1965, with ITV on Channel 11. It was built at Balcalk Hill.

### Opening

The first broadcasts began on VHF channel 11 in black and white, from 13 October 1965 A new television production site in Dundee, was to be later built.

### Transmission

Trade testing of BBC2 in colour began on Monday 14 July 1969, to go into full service on Monday 28 July 1969 on channel 68.
BBC1 in colour began from Saturday 2 October 1971, for 300,000 viewers, six months early.
In May 1972, the ITA announced that ITV would broadcast in colour from September 1972. ITV would go colour from Saturday 30 September 1972.

## Coverage area
