Belmont Transmitter                                               OS Grid Ref TF 218 836

Note As work takes place on various digital transmitters (to prepare for the DSO)
 you may experience problems, e.g. with certain MUXES disappearing.
First try rescanning your set top box and if this fails to work check on Transmitter work  
or phone reception advice on 08700 100 123 (BBC) or 0844 881 4150 (ITV).

Belmont television transmitter is situated 18 miles ENE of Lincoln and is a "guyed mast". Built in 1959, it`s the tallest structure in the UK at 385m (1270ft). Think about it, that`s nearly a quarter of a mile in height ! As a comparison, the tallest building in Britain is
Canary Wharf and that is only 244m high. At 500kW (analogue) Belmont is very powerful, though C5 is only broadcast at one tenth of this power.
Digital at between 4 to 10kW. MUX2 is now transmitted at 20kW, some sources still quote 10kW but our tests indicate that it is higher power than the others !
MUX 3 & 4 are 10kW and MUXES 1, 5 & 6 are at 4 to 5kW.
Belmont`s coverage area is huge because the topography around Lincolnshire is so flat and this explains why it only has five smaller relays (or repeaters) to improve coverage in poor reception areas within its coverage area. Even in Sheffield (55miles away) many of those with clear views East (see Topography map) can use Belmont if Crosspool and Emley are problematic.  In terms of population it serves around 1.5 million including the towns/cities
of Hull, Lincoln, Nottingham, Peterborough, Grimsby and Mansfield.
The transmitter is Horizontally polarised and was originally an A group.
Unfortunately it has gone wideband to accommodate C5 and Digital/Freeview although
MUX1 (the main BBC channels) is on channel 30 and so those with an A group aerial
should receive that particular MUX OK. Those requiring all the digital channels will almost certainly need their antenna changing, see Belmont graph.

Belmont, all 385m of it, from one of the outer anchor points. There are three sets of the

latter and each one has two stays thus giving the six stay levels of the mast.

Belmont is the only transmitter with this number, unsurprisingly as it is the tallest.

Belmont actually has an internal lift but there is a rumour that an accident (serious but not fatal) has caused it`s use to be reassessed...... During a recent conversation with one of

the team of painters who maintain the structure he revealed that a hoist is used the ascend the first 500 ft but from then on it`s a ladder. He said it takes him an hour and a half to

reach the top (remember he`s got to carry all his paint and safety gear) but only 20 minutes to get back down again !                                                          Picture Justin Smith ATV

transmission signals up the mast.                                          Picture Justin Smith ATV.

Belmont`s channels in relation to the UHF TV band and the gain curves of the aerials

we recommend for it.   DM Log    Log40     XB10WB     XB16WB

Note the channels out of the original A group of the transmitter including analogue C5, so if you get the latter then you already have a wideband aerial ! Also note that Digital MUX 1 is

Within the original A group so would be receivable without an wideband.

For Belmont`s frequencies see its Channel Allocation Guides below, for before

and for after the DSO

Belmont`s Pre DSO Channel Allocations (above)

Also check Belmont`s five smaller relays

 

Belmont`s Post DSO Channel Allocations (below), apart from its other uses this guide shows clearly that Belmont will remain a wideband (for two of the six MUXES) after DSO.

Note the gaps in the table below for channels 31 to 35, 37, 39 to 40 and 63 to 68, they`re reserved for “other uses”....

For Belmont`s frequencies see its Channel Allocation Guides for before and after the DSO. The guides also include the same information for some of the other transmitters in Belmont`s coverage area, namely Tacolneston, Sudbury, Sandy, Waltham,

Sutton Coldfield, Nottingham, Chesterfield, Sheffield, Emley Moor, Bilsdale and Olivers Mount. This data can be very useful in the diagnosis of co-channel interference problems. The Channel Allocation Guides can also be invaluable if you are trying to find a spare

channel for a modulated output (e.g. for a Sky box or CCTV system) to be added to your

TV setup/distribution system without suffering from co-channel.

Ofcom reports that CH30, CH57 & CH60 are essentially omnidirectional, CH48 has a slight notch at 100 degrees, and CH66 & CH68 slight attenuation to the East.

DSO is due to occur for Belmont in July 2011. Rather surprisingly it has been

confirmed that Belmont will  stay a wideband at DSO. However the main PSB MUXES (plus MUX 4) will be receivable on an A group.  

Those situated to the West of Belmont (including the Sheffield area) may find that during certain weather condition they can suffer from co-channel interference as their aerials are pointing towards the continent. If you are on Belmont and suffer this type of co-channel you may find the use of an attenuator helps alleviate the problem.

In addition to it`s TV output Belmont transmits BBC National FM (at 16kW), BBC Radio Lincoln (94.9MHz at 6kW and DAB Radio at 10kW).

We recommend the DM log for strong signal areas, the Log 40 for medium signal areas,

the XB10WB for poor signal areas and the XB16WB for those with the most marginal signals. The dimensions and test performance of the aerials can be found on the

relevant tables. The prices of the aerials are on the Sales page.
