Keighley transmitter is a steel lattice tower about 51m high which is situated on the hill and 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. It was originally a C/D group for the analogue channels and still is for all 6 digital MUXES, see Keighley`s graph.
Keighley`s power output is 2kW for all its digital output.
Before the switchover it was only 100W !
For Keighley we recommend the DM log for strong signal areas, the Log36 for medium signal areas, the Yagi18CD or 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.
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 occurred at Keighley between the 7 and the 21 of September 2011.
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-
There are no interleaved spectrum channels allocated to Keighley in the latest scheme.
A slight chance exists of more TV channels being transmitted between CHs 31 and 37, These can by picked up be (decent) C/D group aerials but it must be admitted that an E group (or wideband) aerial would work better.

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.
Also see basic digital fault finding.
Switchover occurred at Keighley in September 2011.
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.

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.
Keighley Town was installed top of the flats on Parkwood Rise in 1979. It is a repeater which receives its picture from Keighley, thus it`s a repeater off a repeater ! Keighley Town only transmits MUXES 1 to 3 (the PSBs), not all six of them. All of its digital output is within the original A group. Location of Keighley Town transmitter

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.
On the left is Keighley Town transmitter`s receiving antenna whilst on the left is a picture of its transmitting array. Both are found on the top of the flats on Parkwood Rise.
Note the use of a Log Periodic as the receiving antenna.
