UKTX in numbers

What Ofcom's published data — and, where a sweep has run, our own model of it — actually add up to.

Installations, by band

2,904 site rows across four bands [V]. A site row is one entry in Ofcom's data, not one physical mast — a mast carrying television and FM from the same structure is two rows here, joined on the transmitter page but counted once per band.

Radiated power, by band

42,498 kW published across every service, summed straight from Ofcom's ERP figures [V] — FM as the sum of its horizontal and vertical planes, where a station radiates both.

Output Areas, by best-serving DTT transmitter

Of 238,877 Output Areas the television sweep covers, these 15 transmitters are each the single strongest signal in the most of them [I] — modelled, not measured, and optimistic by an amount that is measured separately.

How the record is joined together

811 pairs of site rows are recorded as the same physical transmitter, 746 of them on verified evidence [V] — an identical grid reference, or positions within 50 m — and 65 on inferred evidence [I], a position within 400 m and a matching name. Nothing else on this site merges two source rows into one mast.

How current the data is

Ofcom date FM, DAB and medium-wave records individually; television carries no per-record date at all, so its currency is Ofcom's file as a whole, not a span. [V]
