x If it is considered that sufficient installation height cannot be provided when the antenna is
installed directly on the roof of the wheelhouse, use a mounting rack or radar mast (FIG.3).
Normally, when the antenna installation height is less than 2 meters from the roof of the
wheelhouse, provide a mounting rack assembled at an angle frame to install the antenna.
When the antenna installation height is 2 meters or higher from the roof of the wheelhouse,
provide a cylindrical radar mast to install the antenna. Consider the convenience of the
service staff who take care of installation, maintenance, adjustment, and repair of the
antenna by providing adequate footholds to the mounting rack and the radar mast.

x When installing the antenna, select a location where there are the fewest structural objects in
the surrounding area so that false images which interfere with target detection will not be
generated by signal reflection from other antennas, deck structures, and cargo. Only as a
guide, note that structural objects should not exist within the range of the vertical beam
width (Fig.4).
Vertical beam width of X-band: Approx. 20q (r10.0q when the height of the radiating
section is 0q)
