Pattern values are treated as dB attenuation. The outer ring is the lowest attenuation / strongest direction; radius uses field-strength scaling: 10−dB/20.

Best bearing(s): 10°, 20°, 30°, 180°, 190°, 200°, 210° at 0 dB attenuation.

Deepest restriction(s): 100°, 110°, 120°, 280°, 290°, 300° at 14 dB attenuation.
