700MHz clearance occurred at Emley Moor on the 5 Feb 2020, technically it became a Kgroup but alldecent B group aerials will work just as well or even better.
The Leeds local CH moved from 56 to 39, but that is actually better for the B group !

Atemporary 310m mast was in use from May 2018 to to Sept 2023 to enable transmissions to continue whilst the existing mast’s antennas are being modified to prepare for the 700MHz clearance.
See pictures of its construction on thisthis MB21 link, and a video of its dismantling onthis BBC news link.

Emley Moor tower is the tallest free standing structure in the UK at 328m (a.g.l), that’s 1084 ft. The Shard (2012) is “only” 310m high.
Incidentally,how high is high ? Andhow long would it take for a spanner, dropped off Emley tower, to hit the ground ? ! ?

The veryfirst Emley Moor transmitter was a125m steel lattice tower* built in 1956 to broadcast ITVon the old 405 lineVHF system. As such it worked in tandem with the originalHolme Moss mast, which transmitted the BBC channel on VHF, only one programme remember because BBC2 didn’t start till 1964. Duplicated transmitters were/are also used atSutton Coldfield / Lichfield,Crystal Palace / Croydon andPontop Pike / Burnhope amongst others. BBC2 started625 line UHF transmissions -in colors ! - from the second (ill fated) Emley mast in 1967.
As a matter of interest the short lived 1966 mast (see below) never transmitted BBC1 at all and only transmitted ITV onVHF because BBC1 and ITV did not start transmitting on UHF - in colour - until November 1969 (i.e. after the Emley Moor UHF transmitter had collapsed, see below).

*This 1956 structure was rebuilt atCraigkelly in 1971 to provide UHF TV to SE Scotland.

The next transmitter, built in 1966, was a cable stayed mast [the same design asBelmont built by BICC. This mast was even taller than the present structure at385m, but this infamously blew down in March 1969. One theory was that a weak point in the design was found wanting by the unprecedented weather, possibly due to the wind setting up oscillation in the structure. Others speculated that there was so much ice on the cable stays that the weight broke them, after that the mast was doomed.... It had only been up for 3 years ! A 61m temporary mast was bought in and this replacement mast began transmitting just 3 days and 23 hours later, impressive......Later a taller204m interim mast was sourced from Sweden and a team of Polish riggers were bought in to erect it. It was rumoured they were the only people who were willing to work in the winter conditions prevailing at the time ! This taller temporary mast was in use within a month, even more impressive……

The present Emley Moor tower started transmissions on the 21 Jan 1971 and it is an elegant tapered concrete structure. In fact, to many people, Emley is iconic and fully deserving of the Grade 2 listed status it received in 2002. Emley Moor transmitter was originally owned by the ITA (Independent Television Authority) then it was sold off to NTL and finally to Arquiva (sic). This area of high ground is perfect for RF (Radio Frequency) transmission and bothHolme Moss andMoorside Edge transmitters are visible (SW and WNW respectively) from the site.

As one travels North on the M1 Emley is on the left. Whenever I return back home from a long journey, I find the sight of Emley somewhat comforting, I know there isn’t long to go now ! Incidentally, this stretch of the M1 was opened in 1968, doesn’t time fly.....

Emley Moor’spopulation coverage is the fourth highest of any UK transmitter at about 4 million people and its signals are received in many large towns/cities including Sheffield, Leeds, Bradford, Huddersfield and Doncaster.

Emley Moor transmitter's channels and powers

For the most up to date MUX to channel allocations etc put this postcode HD8 9TFinto the Freeview checker.
Also seeYorkshire region Freeview transmitters.

Emley is a powerful transmitter, in fact it’s the the6th most powerful transmitter in the whole of the UK.
Note the huge power increase after the 2011 digital switchover.

Emley Moor has always been aB group. Technically (since Feb 20) it is aK group though the difference for Emley's channels is so slight as to be immaterial, at least for decent aerials. All aerials on Emley should be horizontally polarised.

You can confirm if you are on Emley if you receive yourlocal Calendar news from Leeds, rather than from Hull (which would be fromBelmont).Ofcom report Emley’s digital output as being essentially omnidirectional, which is somewhat surprising because there are hardly any people living to the SW of it !

Emley Moor hasfifty six (including Sheffield and Chesterfield)repeaters to improve its signal coverage, particularly in the hilly areas of the Pennines.

There is one ”Local” channel allocated to Emley Moor, on CH39 (Feb 2020 on) for a Leeds local TV station.

For Emley Moor we recommend theYagi10K for strongsignal areas, theLog36 orYagi18K for medium signal areas, theYagi18B for outdoor installs in poor signal areas, theXB10B for loft installations in poor signal areas, and theXB16B for those with the most marginal signals. Unless you have a massive loft we’d normally recommend an XB10B for loft installs (over an XB16) due to smaller size of the former aerial. The dimensions and test performance of the aerials can be found on the relevant buy pages.

Emley Moor television transmitter, all 1084ft of it...... The structure may look solid* but according to someone who works there it sways in the wind and this can sometimes induce sea sickness to those working in the microwave link room Picture below) when gales are about ! Incidentally the structure is designed to withstand winds of up to 150 mph.

* The foundations consist of a solid concrete annulus of 8.2m width and 6.1m depth with a thickness of 4.3m and that’s a lot of concrete.......

See Emley’s heightin relation to other transmitters.

Emley Moor TV transmitter as you’ve never seen it before.......

The ring marks in the concrete will be noted, this is where theshuttering was used to build the structure. Because the tower is tapered the shuttering’s diameter had to be reduced each time a new (higher) section was added.

The whole structure weighs 11,200 tons.

Note that Emley Moor is not a “mast” because it’s a self supporting structure, it’s actually a “tower”. Masts arecable stayed, likeWinter Hill for example.

Top of Emley Moor transmitter showing the microwave link room, also note the spiral structure at the top to deflect wind upwards.

The link room is at 262m and one (of the two) lifts goes straight to this level. Despite this it still takes seven (seven ! ) minutes to do so. The other lift provides engineers access to all the different levels, but you could always use the ladder(s), with a total of 865 rungs......

It’s a tall building that can have (only) it’s head in the clouds.....
This picture was taken from near theNational Coal Mining Museum which is definitely worth a visit, and it’s free !

A temporary mast was erected at Emley Moor (between May 2017 and May 2018) in order to allow the700MHz clearance work to proceed on the original tower’s transmitting arrays without interruption. It was up for longer than anticipated but finally dismantled from early Sept 2023. The power output was due to be the same as the original mast, but the radiation pattern was actually slightly more omni directional !

A temporary mast was also used atSutton Coldfield andRowridge (amongst other sites) during the digital switchover.

The temporary mast just looks taller because of the photo’s perspective, in actual fact the original tower is slightly higher (at 328m to 324m).

There’s tall and there’s tall....

Well Emley Moor is pretty high, to be honest I wouldn’t really want to clean the windows on the microwave link room (picture above), but Belmont is taller (385m as originally built) and the “Taipei 101” [509m] overshadows both of them....

The three of them are pictured in scale, more or less, on the right.

Until the Burj Dubai (828m) was completed in Jan 2010 the Taipei 101 in Taiwan was the tallest building in the world, and it’s bleedin’ huge. My wife, our lad and I went up it and unsurprisingly the lifts are the worlds fastest (at 38mph) and it only took 37 seconds to get to the 89th floor !

Incidentally we only went to Taiwan because we got a cheap flight to Australia via Taipei and we broke the journey there, but we really liked it. It’s a fascinating country (a cross between Japan and China ? ) but the best thing about it is the people have got to be some of the friendliest I’ve ever met, and there are plenty of McDonald’s for the kids….

Emley Moor transmitter’s Channel Allocations

The channel guide below also includes the same data forBilsdale,Belmont,Waltham,Sutton Coldfield,Chesterfield,Sheffield, Idle, Keighley and Beecroft Hill. This information can be useful for suggesting alternative transmitters should Emley prove problematic.
The channel allocation guides can also be very useful in the diagnosis of co-channel interference problems and can also be invaluable if you are trying to find a spare channel for amodulated output (e.g. for a Sky box or CCTV system) to be added to your TV setup/distribution system without suffering from co-channel.
