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°, 80°, 90°, 100°, 110°, 250°, 260°, 270°, 280°, 290°, 300° at 0 dB attenuation.

Deepest restriction(s): 0°, 160°, 170°, 180°, 190° at 2 dB attenuation.
