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): 130°, 140° at 0 dB attenuation.

Deepest restriction(s): 210°, 220°, 230°, 240°, 250°, 260°, 270°, 280°, 290°, 300°, 310°, 320° at 12 dB attenuation.
