5.2.2 How to install Antenna
1. Take a caution when antenna is installed on High Speed Vessel
Generally the head of High Speed Vessel will be up float when ship is in full speed.
Due to this, in case the Antenna being installed in even level and trim (angle of
②hip ② ②③em while ①④nning) being ove① 1/2 of ve①③ical beam wid③h
(θ), ③he Echo f①om
this target is hardly displayed as image because the front of the ship is off the beam
range that causes the electric wave reflecting from the target becomes weak. In
opposition, at the stern of the ship the wave reflecting from the sea surface
becomes strong. It will not affect the image at the port and starboard side of the
ship.

2. Caution while the Antenna is installed in Yacht
It is apt to be sliding in slant toward the counter windy side while the yacht is
navigating when the wind is blowing to the extent. In case the slanted angle being
over 1/2 of beam width, the electric wave reflecting from the target becomes weak
since the ship structure is off the range of beam and Echo from this target is hardly
displayed as an image. In opposiiton, the opposite side of the wind, surface
reflecting becomes strong since the electric wave contacting sea surface becomes
strong. But it will hardly affect the images of fore and after side of ship.
Therefore, in case Ya

recommended to install the mounting bracket in order that antenna may be slanted in
right and left side according to the angle of slant.
