Additional information
˿
If the roadway is frequently used by tall vehicles, consider
choosing a higher mounting height to help avoid occlusion.
˿
Don’t use an oset of less than 6 ft. (1.8 m). Also, the sensor can
be up to 230 ft. (70.1 m) from the road, but don’t go out that far if
you can avoid it; it could lead to decreased accuracy.
˿
For best results, choose the mounting height in the Height
column in the table. If you can’t, just keep it somewhere in the
acceptable range.
Occlusion and multipathing
These are two problems you might face while using a radar
detector.
Note. Some
countries, such as
the UK, have their
own variant of these
mounting guidelines
due to dierences
in road layouts and
trac profiles. Please
consult with your
local Wavetronix
oce to ensure
you are installing
to the correct
local guidelines.

Recommended
Warning. Choosing
a mounting
height outside
that range could
negatively aect
sensor accuracy.
