Radar to stop aerial collisions

• Prevents planes and helicopters colliding with
  high-tension lines, wind-turbines,
  telecommunications masts, etc.
• A mast fitted with radar and data equipment is
  installed near the obstacle

  when an aircraft is 30 seconds away if it
  approaches to within 20 seconds a VHF transmitter
  is activated and an auditory signal is dent to
  the pilot.
