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): 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 350° at 0 dB attenuation.

Deepest restriction(s): 160°, 170°, 180°, 190°, 200°, 210°, 220°, 230°, 240° at 4 dB attenuation.
