Determining the Radar Mounting Height

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

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

2 Use this equation to determine the mounting height of the radar based on the distance you measured in the

previous step:

(Distance (mm)

(Distance (in.)

× 0.222) - 6 = height (in.)

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.

× 0.222) - 150 = height (mm)
