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): 150°, 160° at 0 dB attenuation.

Deepest restriction(s): 30°, 40°, 50°, 60°, 70°, 240°, 250°, 260°, 270°, 280°, 350° at 27 dB attenuation.
