Determining the Radar Mounting Height

NOTICE

If you plan to install the radar on a roof or hard top, you should install it high enough to avoid interference from the surface.

  1. Based on the shape of the roof, complete an action:
    • Measure the distance from the intended mounting location to the furthest front corner of a rectangular roof 1.

    • Measure the distance from the intended mounting location to the front apex of a curved roof 2.


    Measuring the location of the dome on the roof with callouts
  2. Use this equation to determine the mounting height of the radar based on the distance you measured in the previous step:

    Graph to determine the appropriate height of the radar with callouts

    (Distance (mm) 3 × 0.222) - 150 = height (mm) 4

    (Distance (in.) 3 × 0.222) - 6 = height (in.) 4

    For example, if the mounting location is 2 m (6.6 ft.) from the corner of the roof, this is how you would complete the equation to determine the mounting height after converting to mm (or in.):

    (2000 mm × 0.222) - 150 = 294 mm

    (78 in. × 0.222) - 6 = 11.3 in.

  3. Install a riser or other fixture so the base of the radar is equal to or higher than the distance you calculated in the previous step.
