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): 60°, 70°, 300°, 310° at 0 dB attenuation.

Deepest restriction(s): 150°, 160°, 170°, 180°, 190°, 200°, 210°, 220° at 20 dB attenuation.
