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): 260°, 270°, 300°, 310°, 340°, 350° at 0 dB attenuation.

Deepest restriction(s): 130°, 140°, 150°, 160° at 22 dB attenuation.
