Local transmitter information

TransmitterWe are based in Hull, East Yorkshire and the vast majority of our customer’s receive their aerial signal from the Belmont Transmitter which is near Louth in Lincolnshire a distance of approx 40 miles away, some customers to the west of Hull receive their signal from the Emley Moor Transmitter, West Yorkshire.

Television reception nationally is transmitted on a band between 470-862MHz or channels 21-69 to make life easy, this band was divided into 3 groups:

A group 21- 34
B group 39-53
C/D group 48-68

This was to avoid reception problems in overlapping areas. Belmont customers historically used a group A aerial, Emley Moor a group B. The TV channels are now transmitted across the whole band 21-69 so a new installation would usually use a wideband aerial capable of picking up 21-69

From this information a customer who receives from Belmont with an old group A aerial will only pick up the bottom third of the band – this will allow them to receive analogue BBC1, BBC2, ITV1, CH4 and the lowest digital multiplex (channel 30); which will give digital BBC1, BBC2, BBC THREE, CBBC CHANNEL, BBC NEWS, BBC RED BUTTON.

Customers who get reception from Emley Moor generally fare better as most of the digital channels can potentially be picked up with a B group aerial.

The only option if you receive from Belmont and have an old A group aerial is to have it replaced if you wish to receive all the digital channels.

Analogue CH5 from the Belmont transmitter is transmitted on channel 56 which is in C/D group, from this, there is a sweeping generalisation that if you receive from the Belmont Transmitter and you can pick up CH5, then that indicates that you have a wideband aerial and you are fully ready for the digital switchover, if only it was that easy; though a good picture on CH5 from Belmont indicates that you don’t have a group A aerial it doesn’t guarantee digital reception.

Digital reception has some pros and cons, on the plus side we have more channels and reliable picture on the minus side if we don’t receive enough signal we have picture break up (pixelation), sound distortion and missing channels.

The key to a successful installation is to receive enough signal on all the digital multiplexes
