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): 310°, 320°, 330°, 340° at 0 dB attenuation.

Deepest restriction(s): 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, 190°, 200°, 210°, 220°, 230°, 240°, 250°, 260° at 20 dB attenuation.
