For Emley Moor we recommend the DM log for strong signal areas, the Log36 for medium signal areas, the Yagi18B for outdoor installs in poor signal areas, the XB10B for loft installations in poor signal areas, and the XB16B 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 tables.
Emley Moor`s population 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.
There is one interleaved spectrum channel allocated to Emley Moor, CH 56 (which is more or less within the B group) for a potential Leeds local TV station. It must be admitted that at CH56 a B group may be a little down in gain on some widebands, but it should still be working reasonably well up there. This may not apply to some cheap crappy B group Contract aerials.
In addition, there are two planned lower power HD MUXES to be transmitted (in the CH 31 to 37 gap) on CHs 32 and 34. Both of these channels can be picked up by decent B group aerials.
Note, due to the new phenomenon of MUXICAL chairs you may experience problems with certain MUXES disappearing. First try rescanning your TV / set top box, do it manually if possible. If this fails to sort it check on transmitter work or call the reception advice phone numbers.

Switchover occurred at Emley Moor in September 2011.
We are more than willing to give advice to those actually purchasing from us. Could those only seeking information please just find the answer somewhere on this site, or ring an aerial installer local to them, or call the reception advice phone numbers.

Incidentally, how high is high ?
And how long would it take for a spanner, dropped off Emley tower, to hit the ground ? ! ?
The very first Emley Moor transmitter was a 125m steel lattice tower* built in 1956 to broadcast ITV on the old 405 line VHF system. As such it worked in tandem with the original Holme 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 at Sutton Coldfield / Lichfield, Crystal Palace / Croydon and Pontop Pike / Burnhope amongst others. BBC2 started 625 line UHF transmissions 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 on VHF.
* This 1956 structure was rebuilt at Craigkelly in 1971 to provide UHF TV to SE Scotland.
The next transmitter, built in 1966, was a cable stayed mast [the same design as Belmont] built by BICC. This mast was even taller than the present structure at 385m, but this infamously blew down in 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 taller 204m 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. Just like the previous transmitters it is situated about half way between Huddersfield and Barnsley. This area of high ground is perfect for RF (Radio Frequency) transmission and both Holme Moss and Moorside Edge transmitters are visible (SW and WNW respectively) from the site. Emley Moor was originally owned by the ITA (Independent Television Authority) then it was sold off to NTL and finally to Arquiva (sic).
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 is a powerful transmitter, in fact it`s the the 6th most powerful transmitter in the whole of the UK. Note the huge power increase after the digital switchover.
You can confirm if you are on Emley if you receive your local Calendar news from Leeds, rather than from Hull (which would be from Belmont). 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 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 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.......
Emley Moor TV transmitter as you`ve never seen it before.......
The ring marks in the concrete will be noted, this is where the shuttering 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.
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......
Emley Moor by night. Note the red glow, of the top navigation light, on the cloud just above the transmitter. Picture dedicated to my wife who was getting impatient as I farted about with exposure settings etc....
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, but Belmont is taller (385m as originally built) and the “Taipei 101” [509m] makes them both look like midgets....
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 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. It`s like a huge National Trust property in that everyone is so nice to everyone else !

If you`ve found this site informative and, hopefully, interesting as well,
The channel guide below also includes the same data for Bilsdale, Belmont, Waltham, Sutton Coldfield, Chesterfield, Sheffield, Idle, Keighley and Beecroft Hill. This information can be useful for suggesting alternative transmitters should Emley prove problematic.
