The '''Winter Hill transmitting station''' is a [[broadcasting]] and [[telecommunication]]s site on [[Winter Hill (North West England)|Winter Hill]], at the south eastern boundary of the [[Chorley (borough)|Borough of Chorley]], [[Lancashire]], England, and above [[Bolton]]. It is owned and operated by [[Arqiva]].

==Height==
The original mast at Winter Hill was a {{convert|450|ft|m||order=flip|adj=on}} tower that came into service on 3 May 1956, and carried the programmes of [[Granada Television]] (weekdays) and [[ABC Weekend Television]]. In 1966 services were transferred to a new higher mast erected adjacent to the original tower. The main mast structure is {{convert|309.48|m|ft|}} tall and has a diameter of {{convert|2.75|m|ft}}. During the period of parallel digital and analogue transmissions, the [[Digital terrestrial television|DTT]] [[antenna (radio)|antenna]] attached to the top of the mast brought the overall height to {{convert|315.4|m|ft}},<ref name="ChorleyCC">[http://planning.chorley.gov.uk/PublicAccess/tdc/DcApplication/application_detailview.aspx?caseno=JCBKD6ETO3000 Chorley Council - Planning Applications - Ref: 07/00056/FUL]</ref> however as part of the Digital Switchover plans, this antenna has now been removed, reducing its overall height to {{convert|309.48|m|ft}}.<ref name="ChorleyCC"/> It is one of the tallest structures in the [[United Kingdom]], the tallest being [[Skelton Transmitting Station|Skelton mast]]; however, at {{convert|778.1|m|ft}} above sea level, Winter Hill has the highest television transmitting antenna in the United Kingdom and is higher than [[Green Hill (Lancashire)|Green Hill]], the highest hill in [[Lancashire]].

== Construction ==
[[File:Winter Hill TV Mast.jpg|thumb|250px|A view of the mast from beneath, illustrating the tubular structure]]
Unlike most masts, which are of a lattice design, Winter Hill mast is of a tubular construction. Five other masts in England share this design ([[Belmont transmitting station|Belmont]], [[Bilsdale transmitting station|Bilsdale]], [[Mendip transmitting station|Mendip]], [[Waltham transmitting station|Waltham]] and the original ill-fated structure at [[Emley Moor transmitting station|Emley Moor]]).

Support wires, to hold the mast vertical, are pitched at 120° when viewed from above. These are connected at five heights, giving 15 supports in total. These wires have been strengthened, and {{convert|152|MT|LT|abbr=off}} of dampening chains have been fitted by [[Arqiva]] (then NTL Broadcast) to reduce the oscillations caused by high winds that were a factor in the collapse of [[Emley Moor transmitting station|Emley Moor]]'s original structure in 1969. During 2007 - 2009, the mast was strengthened to allow the installation of the new heavier digital transmission aerials.<ref>[http://tx.mb21.co.uk/gallery/gallerypage.php?txid=271 The Transmission Gallery - Winter Hill]</ref> Its ropes weigh 85 tons, made by [[British Ropes]], with steel from [[Steel, Peech and Tozer]] of [[Templeborough]] in southern Yorkshire. The column weighs 210 tons and has 375 segments, with steel from [[United Steel Companies]] at [[Scunthorpe]] in northern [[Lincolnshire]].<ref>''Times'' Friday 10 September 1965, page 9</ref>

== Maintenance ==
An advantage of the tubular design is that engineers can ascend the inside of the mast and avoid adverse weather, which is a problem on frame structures. Maintaining the outside of the mast is typically performed using a [[bosun's chair]].

The mast has always had a series of red [[aircraft warning lights]] but in October 2006 these lights were substantially brightened making the mast far more visible to passing aircraft. These lights can be maintained from the inside, as the lamps swing inwards for maintenance.

Eight external platforms encircle the mast along its height. These can be accessed from the inside of the mast, and are used to maintain the supporting wires, and the [[Independent Local Radio|ILR]] antennas.

== Coverage ==
{{Original research|date=March 2018}}
The station's [[coverage map|coverage]] includes approximately 6.3 million people. The coverage area is for mainly Greater Manchester, Merseyside, Lancashire, Cheshire and southern Cumbria along parts of Derbyshire, Staffordshire and North Yorkshire. Relay transmitters are needed around eastern Manchester, northern Lancashire and the Wirral peninsula. The transmitter also covers the North Wales coastal areas and although not the 'correct' television region, it is the preferred region for some in [[North Wales]], mainly because it carries [[Channel 4]] (as opposed to [[S4C]], however since digital switchover Channel 4 is also available on all Welsh transmitters), [[Channel 5 (UK)|Channel 5]] and a much more powerful{{quantify|date=March 2018}} [[digital terrestrial television|digital terrestrial]] output than the Welsh transmitters. The region's [[ITV (TV network)|ITV]] franchisees, [[ITV Granada|Granada Television]] (weekdays only until 1968) and [[ABC Weekend TV]] (launched in 1956), were on air much earlier than North Wales' franchisee, [[Wales West and North Television|WWN (Teledu Cymru)]] which launched in 1962 (subsequently HTV Wales) giving viewers more choice than they would with the Welsh transmissions. ABC Television lost its franchise in 1968, when Granada Television commenced broadcasting seven days a week. Since the [[Digital terrestrial television in the United Kingdom#Digital switchover|digital switchover]], the Welsh transmitters are broadcasting DTT at a much higher power and Channel 4, and Channel 5 are now included in the line-up. However, because of the terrain and the rough landscapes of North Wales, many have likely stayed with Winter Hill, not least because small local relays only broadcast a limited range of multiplexes with a reduced number of channels.

===Television===

====Digital====
Winter Hill is the principal transmitter for the North West region (formerly Granada ITV region) and in 2009 it became the first in the UK to broadcast digital television in high definition.<ref>{{cite web |url=http://www.ofcom.org.uk/media/features/hdfree|title=Freeview set for HD channels |work= Ofcom|access-date=2008-10-19|archive-url=https://web.archive.org/web/20081019092320/https://www.ofcom.org.uk/media/features/hdfree|archive-date=2008-10-19|url-status=dead}}</ref><ref>{{cite web|url=https://www.theregister.co.uk/2008/10/17/freeview_hd_2009/|title=Ofcom confirms three Freeview HD channels 'by end of next year' • The Register|publisher=www.theregister.co.uk|access-date=2008-10-19}}</ref>

Winter Hill's 700MHz clearance will end on 10 February 2020 when, somewhat surprisingly, Winter Hill will become an A group (excluding MUX 7 which are due to be switched off before the end of 2020 anyway). Because the A group is the opposite end of the band from Winter Hill's C/D, people with original C/D group aerials in poor signal areas may struggle to pick up the signal (see [https://www.aerialsandtv.com/knowledge/transmitters/winter-hill-transmitter#winter-hill-graph Winter Hill graph]).  

Only four of the 70 Winter Hill relays broadcast six digital multiplexes (Lancaster, Saddleworth, Pendle Forest and Storeton). All the others broadcast just the three public service multiplexes BBC A, BBC B and D3&4. Winter Hill also broadcasts a Manchester multiplex on Channel 27{{Citation needed|reason=An up to date source needs citing about the GImux (G_MAN) multiplex|date=January 2021}}.

=====Present channels=====

These were moved around until February 2020 due to the 700MHz clearance.

===Digital television===
The following is a list of the television relays served by Winter Hill, including UHF channels for each multiplex it carries. Only Lancaster, Pendle Forest, Saddleworth and Storeton carry all the main 6 multiplexes and have done so since 1998 when Winter Hill also started broadcasting these channels. Before 2009, the Cornholme, Lydgate, Todmorden, Walsden and Walsden South transmitters in [[West Yorkshire]] also relayed signals from Winter Hill, until this was changed to relay [[Emley Moor transmitting station|Emley Moor]] in 2009.

== Plane crash ==
{{main|Winter Hill air disaster}}
On 27 February 1958, a [[Silver City (airline)|Silver City]] [[Bristol 170 Freighter]] (G-AICS) travelling from the [[Isle of Man]] to [[Manchester]] crashed into Winter Hill (also known as Rivington Moor) several hundred yards away from the mast. Thirty-five people died and 7 were injured. The weather that night was so severe that none of the engineers working in the transmission centre were aware of the crash. Several feet of snow hampered rescue efforts, and a [[snowcat]] vehicle had to be diverted from the [[A6 road (Great Britain)|A6]] to cut a path for emergency vehicles.
