1. INSTALLATION
1-2
• Do not install the antenna where extreme winds may strike the port and starboard
sides of the antenna.
• Install the antenna unit away from interfering high-power energy sources and TX ra-
dio antennas.
• Keep the lower edge of the antenna unit above the safety rail by at least 500 mm.
• Install two antenna units as shown in the
right figure.
• No funnel, mast or derrick shall be within the vertical beamwidth of the antenna unit
in the bow direction, especially zero degree ±5°, to prevent blind sectors and false
echoes on the radar picture.
• It is rarely possible to place the antenna unit where completely clear view in all di-
rections is available. Therefore, you should determine the angular width and relative
bearing of any shadow sectors for their influence on the radar at the first opportunity
after fitting.
• Locate the antenna of EPFS clear of the radar antenna to prevent interference to
the EPFS. A separation of more than two meters is recommended.
• A magnetic compass will be affected if the antenna unit is placed too close to the
magnetic compass. Observe the compass safe distances on page ii to prevent in-
terference to a magnetic compass.
• Do not paint the radiator aperture, to ensure proper emission of the radar waves.
• Ground the unit with the ground wire (supplied).
• Deposits and fumes from a funnel or other exhaust vent can affect the aerial perfor-
mance and hot gases may distort the radiator portion. Do not install the antenna unit
where the temperature is more than 55°C.
• Leave sufficient space around the unit for maintenance and servicing. See the an-
tenna unit outline drawing for recommended maintenance space.
Note: For more information, please refer to IMO SN/Circ.271 “Guidelines for the in-
stallation of shipborne radar equipment”.
