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): 50°, 60°, 320°, 330° at 0 dB attenuation.

Deepest restriction(s): 80°, 120°, 170°, 210°, 220°, 250°, 300°, 350° at 3 dB attenuation.
