Transmitters

7 transmitters, strongest first. TII is the transmitter identifier a receiver can report, which is how you tell which one you are actually hearing in a single-frequency network.

Radiation pattern

Its strongest transmitter with a published pattern, Crystal Palace. Other transmitters of this ensemble may shape their signal differently.

Radiates most strongly toward the south-west (210°), as published by Ofcom.

More detail

Each ring is 10 dB of attenuation below the pattern's own peak; the outer rim is the peak itself and anything 30 dB down or deeper is drawn at the centre rather than off the edge of the chart, so a very deep null reads as “weak” and not as a hole in the picture. The shape says which direction radiates harder relative to the mast's own peak, not the absolute field strength there or how far it reaches — that is what the coverage map and the postcode lookup are for.
