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): 130°, 140°, 150°, 160° at 0 dB attenuation.

Deepest restriction(s): 0°, 10°, 310°, 320°, 330°, 340°, 350° at 19.98 dB attenuation.
