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): 200°, 210°, 220°, 230° at 0 dB attenuation.

Deepest restriction(s): 100°, 110°, 120°, 130°, 290°, 300°, 310°, 320°, 330°, 340° at 30 dB attenuation.
