Note As work takes place on various digital transmitters (to prepare for the DSO)
you may experience reception 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).

Keighley transmitter is a steel lattice tower about 51m high which is situated on the hill a couple of miles North of the town from which it take`s its name. The site height is 303m giving an average aerial height of 354m.
Keighley is vertically polarised and was originally a C/D group but to accommodate
Digital / Freeview it is now wideband. Having said that only MUXES 5 & 6 are out of band
so you should find that the other 4 MUXES are receivable without changing your C/D group antenna. Furthermore C/Ds often pick up signal quite well below their designed for band,
so reception of MUXES 5 & 6 may still be possible, see Keighley`s graph.
Analogue power output is 10kW on the four main channels (there is no analogue C5) and Digital power is 100W.

Keighley & Keighley Town`s Frequencies/Channels

Back to the top of aerialsandtv.com Keighley Transmitter

The transmitter is a repeater (or relay) off Emley Moor, that is to say it receives its signal from Emley, then remodulates it before retransmitting it into the Aire valley which would otherwise be shielded from a decent signal.

DSO is due to occur for both transmitters in September 2011 and it has been confirmed by Ofcom that Keighley will be returning to a C/D group.

Both Keighley and Keighley Town`s frequencies are given on the Channel Allocation Guide. The latter also provides the same information on the potentially co-receivable transmitters of Emley Moor, Bilsdale, Idle, Skipton, Beecroft Hill, Wharfdale and Heyshaw. This can be most useful for identifying co-channel problems and possible alternative transmitters. Note how all the transmitters frequencies "dove tail" together. Keighley transmits at full power to the SW with good signals from SE to NW but transmissions to

the NE are very attenuated. The Channel Allocation Guide 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.

The hill on which Keighley transmitter stands over looks the Aire valley along which the Leeds to Liverpool canal (completed in stages between 1774 and 1816) and the Railway

line to Skipton runs. The line was originally built by the Leeds & Bradford Railway and opened from Leed/Bradford to Shipley in 1846 and on to Skipton (via Keighley) in 1847.

The line passed into the hands of the Midland Railway and this section eventually became part of the route to Carlisle via the virtuoso Settle to Carlisle railway. Perhaps Keighley is most famous these days for being the terminus of the well known Keighley & Worth Valley Railway, this was originally opened by the Midland in 1867 and it became one of the first preserved railways in 1968.

Keighley Town is a repeater (situated on top of the flats on Parkwood Rise) which receives its picture from Keighley, thus it is a repeater off a repeater ! Keighley Town only transmits the basic 4 channels on analogue (at 6W) and it is a vertically polarised A group.

After DSO, in September 2011, Keighley Town will only transmit the three basic PSB MUXES, not all six of them. Click here for the aerials we recommend for Keighley Town.

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 antennas can be found on the

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

Note the use of a Log Periodic as the receiving antenna.

Note that MUXES 5 & 6 are out of the original C/D group of the transmitter. That said, even these two MUXES would be receivable to those in decent signal areas.
