experience problems, e.g. with certain MUXES disappearing. First try rescanning your
TV / set top box (do it manually if possible), but if this fails to work check on transmitter work
or call the reception advice phone numbers. Also see basic digital fault finding.
its site height is 303m, giving an average aerial height of 354m. It started transmissions in
1972 and the tower is a couple of miles North of the town from which it takes its name.
Ofcom quote Keighley`s maximum population coverage as being about 225,000, but that
includes households which may well be on another transmitter with overlapping coverage.
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. Though this
may not apply to some cheap crappy Contract aerials.
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
The frequencies given are for the analogue channels, for (most) digital MUXES add 3MHz.

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.
Keighley has one interleaved spectrum channel, CH 56, allocated to it which is within the
previously announced post DSO 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-
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-
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.

Technically it is only Keighley Town`s receiving antenna that is visible here though !
Keighley`s channels in relation to the UHF TV band and the gain curves of the aerials
we recommend for it. DM Log Log40 DY14WB XB16E
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.
Also see other relevant C/D group curves.
For Keighley we recommend the DM log for strong signal areas, the Log 40 for
medium signal areas, the DY14WB for poor signal areas, and the XB16E for those with
the most marginal signals. The dimensions and test performance of the aerials can be
found on the relevant tables. If requiring a “high gain aerial” in the loft we recommend
the DY14WB over the XB16 because of the former aerial`s smaller size.
Keighley Town was installed in 1979 and is a repeater (situated on top of the flats on Parkwood Rise) which receives its picture from Keighley, thus it`s 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, but they will still be within the original A group.
