6.1. Overview 

(1) 

Proper installation of Radar ensures the performance and safety of it during operation and facilitates the 

maintenance and repair of it, you should carefully pay attention to the proper of installation accoding to the 
instruction. 

(2) Antenna should be installed as high as possible after considering its weight. 
(3) Indicator should be installed inside Wheel House in order make observation efficiently. 
(4) 15m standard cable should be used between Antenna and Indicator.

6.2.2. 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 ship’s stem while running) being 
over 1/2 of vertical beam width (θ), the Echo from 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. 

Therefore, in case the ship that of trim is over 1/2 of vertical beam width (θ), it is recommended to install 
the Antenna in slant toward the ship’s stem. 

 

(2) Caution while the Antenna is installed in Yaucht 

 It is apt to be sliding in slant toward the counter windy side while the yaucht 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.    It will hardly affect the images of fore and 
after side of ship. 
Therefore, in case Yaucht that of slant is over 1/2 of vertical beam width (θ), it is recommended to install the 

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

CAUTION

 

  The  specialist  from  Head  Office  or  Local  distributor  should  carry  out 

installation work. 

 Installation works carried out by unauthorized person can cause out of 

order, performance failure Electric shock.

 

CAUTION

 

 The place where there is no big obstructions on the level of ship’s fore 

and afterside. 

  If  there  is  a  obstacle  on  the  same  level  of  Antenna,  it  may  cause  a 

virtual image. 

 Especially when the virtural image appears on ship’s fore and after side, 

it will be difficult to observe and hardly forecast the danger. 

  The  place  where  there  is  a  near  Funnel  can  cause  the  decrease  in 

performance,  the  defect  dueto  haet,  therefore  it  should  be  installed 
away from such Funnel as far as possible. 

  Please  keep  in  mind  that  Direction  finding  Antenna  and  VHF  antenna 

should be far away from Radar Antenna. 

(Please avoid the situation from tying up said cables with Radar one)
