THE ANGUS TRANSMITTER provides the main UHF service to the Tayside area of Scotland.  It is sited on Balcalk Hill, near the village of Tealing, approximately six miles north of the centre of Dundee.

The station is also the main DAB radio transmitter for the region with BBC National FM radio transmitted from nearby Forfar.

Angus is the most southerly of the main UHF transmitters in the North-East Scotland ITV1 franchise area, formally known as Grampian and currently STV North.

TRANSMISSION STRUCTURE

Transmissions from Angus are carried on a 229.5m (753-ft) triangular cross-section lattice stayed mast, which is held in place by twelve stay-lines secured at ground level by six anchoring blocks.

UHF COVERAGE

The Angus station provides coverage up to a radius of 25-40 miles (depending on direction) and principally serves the city of Dundee, most of Angus County, plus parts of Fife and Perthshire.  

To the direct north and west, the signal from the station is mostly curtailed by the Cairngorms and Grampian mountain ranges, a region which is almost entirely dependent on relays of both Angus and Durris for television coverage.

To the south, the Angus signal crosses the Tay Estuary into North-East Fife, reaching St Andrews, Leuchars and Ladybank.  Here, the Lomond Hills provide a natural cut-off for most of the signal, preventing it from extending significantly into Central Fife.

As a result of these natural barriers, there is no significant overlap from Angus into areas served by either the Craigkelly or Durris transmitters.

 

CHANNEL FIVE

Due to lack of a suitable frequency combined with the station's positioning near the North Sea (providing the potential to interfere with European stations) Angus never carried Channel Five.  A service was however broadcast from Tay Bridge (a UHF relay of Angus) which provided sufficient power to serve those with suitable aerials in the Dundee area.

DIGITAL SWITCHOVER

Re-engineering of the Angus mast in preparation for Digital Switchover took place principally in the latter half of 2008 with the replacement of both the main GRP-cylinder-encased analogue UHF aerial and the original Digital Terrestrial four-level circular aerial.  (See UHF Aerials for images).  

The two stages of the switchover process took place at Angus as follows -

4 August 2010 - Stage 1 (DSO1) 

  • Shutdown of BBC2 analogue on Channel 63
  • Shutdown of Mux1 on Channel 68
  • ITV1 analogue moved for remainder of service from Channel 60 to ex-BBC2 analogue Channel 63
  • Launch of PSB1(BBC A) multiplex on Channel 60

18 August 2010 - Stage 2 (DSO2)

STATION HISTORY

Angus was built by the Independent Television Authority (ITA) for two main purposes, the immediate objective being the provision of improved ITV 405-line VHF coverage to an area that neither the existing ITA transmitters at Black Hill and Durris were serving effectively.  Based on the respective levels of coverage provided by these distant transmitters, both Scottish Television and Grampian Television laid claim to the Angus transmitter, with the ITA settling in favour of the latter.

The site of the new transmitter was close to that of the Forfar station, which the BBC had opened in July 1964 to overcome a similar issue of poor coverage in the Dundee area.  This was to be the last significant example of the ITA siting a 405-line transmitter close to an existing BBC station.

From the 750-ft mast and fully automated transmission facility, the Angus station came into full service on 13 Ocober 1965, operating as a relay of the Durris transmitter and broadcasting on VHF Channel 11 at a peak output of 50kW (vision e.r.p).

The second and ultimately primary function of the Angus transmitter was to provide UHF coverage to Tayside plus areas of Fife and Perthshire, in which capacity the station was designated a main transmitter site.  In accordance with established practice, BBC2 was the first UHF service to be installed, bringing colour television pictures to the area for the first time from 28 July 1969.

UHF transmitters for BBC1 and ITV followed in 1972, whilst Channel 4 came into operation in November 1983.
