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°, 70°, 160°, 170°, 180°, 190° at 0 dB attenuation.

Deepest restriction(s): 250°, 260°, 270°, 280°, 290°, 300°, 310°, 320°, 330°, 340° at 8 dB attenuation.
