Obtaining sufficient dip angle
Raise the antenna position above on-board obstacles to avoid shadow zones. Dip angle is the angle
between a horizontal line and the line of sight from the antenna to the obstacle. By maintaining a dip
angle greater than 5 degrees, you may be able to prevent mid- and long-distance shadow zones. The
radar can't detect objects below its line of sight.

Mounting the radar antenna
It may be easier to install the antenna by fabricating a mounting base, as shown below, but you can
also install the antenna directly to a rigid, flat surface, such as the roof. Pay attention to the water
drain tube at the bottom of the antenna.
