•  The antenna unit is generally installed either on top of the wheelhouse, on the radar mast, 

or on a suitable platform. Locate the antenna unit in an elevated position to permit 
maximum target visibility. 

•  A line of sight from the antenna unit to the bow of the ship should hit the surface of the 

sea in not more than 500 m or twice the ship’s length, depending which value is smaller, 
for all load and trim conditions. 

less than 500 m or twice the ship’s length

•  Mount the antenna unit so that any blind sectors caused by objects (mast, etc.) are kept 

to a minimum. No blind sector should exist in arc of the horizon from right ahead to 22.5

° 

aft of the beam to either side (see Figure 1 below). Also, individual blind sectors of more 
than 5

°, or the total arc of both blind sectors of more than 20°, should not occur in the 

remaining arc (Figure 2). Note that any two blind sectors separated by 3

° or less are 

regarded as one sector.
