UKTX
Television, FM and DAB, from Ofcom's published data
Type a postcode to see which transmitters reach it, or look up a mast directly.
What this is
A reference for UK broadcast transmitters, built entirely from published data. Every television, FM, DAB and medium-wave transmitter Ofcom list, with the channels, frequencies, powers and heights they publish, on one page per mast — which the source files themselves do not do, because television and radio are listed separately and share no site identifier.
2,193 masts, between them carrying 3,831 television multiplex transmissions, 2,095 FM services, 1,385 DAB ensembles with 24,286 station listings, and 95 medium-wave services.
Or look something up by name
Freeview channels — which multiplex carries a channel, and therefore what else disappears with it. Radio stations — every transmitter carrying a station across FM, DAB and medium wave, which is a join Ofcom's three files do not publish. DAB ensembles — the full station line-up of each one. Television regions — why the next village gets different news.
265 channels, 1,358 radio stations, 175 DAB ensembles and 30 television regions have a page.
What makes it different
Reception predictions here are modelled, and the page says so next to the number, along with how far the model has been checked and where it is known to be wrong. See the method. Plenty of sites will confidently tell you the wrong transmitter serves your postcode; the useful thing is not another confident answer but a stated one.
The radio side is better than the television side, which inverts the usual priority. That is not a choice — it is the data. Ofcom publish radiation patterns and RDS identifiers for radio and almost nothing equivalent for television, so FM and DAB predictions here are directional where television's are not.
