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).^[1] It includes a guyed steel lattice mast which is 229.5 metres (753 ft)^[2] 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).^[3] 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 first broadcasts began on VHF channel 11 in black and white, from 13 October 1965

Coverage area

It covers parts of the Dundee City council area, eastern Perth and Kinross, southern Angus and north and east Fife. Reception is also possible in much of north and east Edinburgh and the coastal areas of East Lothian, as far along as the town of Dunbar.^[4]

Analogue and digital

15 November 1998 – 3 August 2010

Digital terrestrial television was first transmitted from the Angus mast from 15 November 1998 using the frequency gaps between the analogue TV broadcasts. To limit interference to the analogue transmissions, power output on the digital multiplexes was low.

4 August 2010 - 17 August 2010

On 4 August 2010, BBC2 was switched off on UHF 63 and STV was switched from UHF 60 for its final weeks of service. Multiplex 1 on UHF 68 was closed and replaced by BBC A on UHF 60 (which had just been vacated by analogue STV). BBC A was transmitted at full power (20 kW) and in 64QAM, 8k carriers mode from the start.

Digital

18 August 2010 to 16 April 2013

Following the completion of analogue TV shutdown on 18 August 2010, Angus transmitted all of its higher powered multiplexes at 20 kW for PSB 1, 2 and 3, and 10 kW for COM 4, 5 and 6. From this date the frequency allocation was:

Frequency	UHF	kW	Operator	System
730.000 MHz	53	20	Digital 3&4	DVB-T
738.000 MHz	54	10	SDN	DVB-T

770.000 MHz	58	10	Arqiva A	DVB-T
786.000 MHz	60	20	BBC A	DVB-T
794.000 MHz	61	10	Arqiva B	DVB-T

17 April 2013 to 26 November 2019

Due to the clearance of the 800 MHz band, Arqiva B was moved from UHF 61 to UHF 49 and BBC A gained a negative offset. Also during this time, COM 7 and 8 and the Local TV multiplex launched.
