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°, 250° at 0 dB attenuation.

Deepest restriction(s): 0°, 50°, 90°, 130°, 140°, 170°, 180°, 270°, 320° at 4 dB attenuation.
