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): 40°, 50°, 60°, 70°, 80°, 220°, 230°, 240°, 250°, 260°, 270° at 0 dB attenuation.

Deepest restriction(s): 140°, 150°, 160°, 170° at 11 dB attenuation.
