Notes:
 1)   Gain variation in elevation shown for the azimuth angle of 0°.
 2)   The x—axis represents the elevation angle and spans from —180° to +180°. Each major axis
      division line represents 20° ofelevation.
 3)   The y—axis represents the antenna gain. Each major axis division linerepresents 2 dB of
