Radiation pattern
Canterbury - Maxted Street publishes the strongest DAB signal for this station with a shape on record — where it is carried elsewhere too, this is not necessarily theirs.
Radiates most strongly toward the north (0°), 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.
