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): 30°, 40°, 50°, 60°, 120°, 130°, 140°, 150°, 210°, 220°, 230°, 240°, 250°, 290°, 300°, 310°, 320°, 330° at 0 dB attenuation.

Deepest restriction(s): 0°, 80°, 90°, 100°, 180° at 2 dB attenuation.
