2.2.4.3  Alternating Mode 
This mode is used to sequentially alternate between up to 5 fixed sectors in azimuth and tilt angles. 
When covering a 360° area around the radar, it is recommended to use either one of the following: 
  To optimize coverage: use 5 sectors spaced at 72° intervals, with a minimum duration of 12 
seconds per sector 
  To minimize scan time: use 4 sectors spaced at 90° intervals, with a duration of 11 seconds 
per sector
