SP03-12500 (DC mains) 000-089-390SP03-12501, SP03-12505 Spare Parts
• The antenna unit is generally installed either on top of the wheelhouse or on the radar mast,
on a suitable platform. Locate the antenna unit where there is a good all-round view.
• No funnel, mast or derrick should be within the vertical beamwidth of the antenna in the bow
direction, especially zero degrees ±5°, to prevent blind sectors and false echoes on the radar
picture.
• It is rarely possible to place the antenna unit where a completely clear view in all directions is
available. Thus, 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 a direction finder clear of the antenna unit to prevent interference to the
direction finder. A separation of more than two meters is recommended.
• To lessen the chance of picking up electrical interference, avoid where possible routing the
signal cable near other onboard electrical equipment. Also avoid running the cable in parallel
with power cables.
• A magnetic compass will be affected if placed too close to the antenna unit. Observe the
following compass safe distances to prevent deviation of a magnetic compass: Standard
compass, 1.70 m (FR-2115-B), 2.10 m (FR-2125-B), Steering compass, 0.90 m (FR-2115-B),
1.20 m (FR-2125-B).
• Do not paint the radiator aperture, to ensure proper emission of the radar waves.
• The signal cable run between the antenna and the display is available in lengths of 15 m
(standard), 20 m, and 30 m. Whatever length is used it must be unbroken; namely, no splicing
allowed.
• The antenna base is made of cast aluminum. To prevent electrolytic corrosion of the antenna
base, use the seal washers and corrosion-proof rubber mat.
• Deposits and fumes from a funnel or other exhaust vent can adversely affect the aerial
performance and hot gases may distort the radiator portion. The antenna unit must not be
mounted where the temperature is more than 70°C.
• Leave sufficient space around the unit for maintenance and servicing. See the antenna unit
outline drawing for recommended maintenance space.
1-1
1.1.2 Assembling the antenna unit
The antenna unit consists of the antenna radiator and the antenna unit chassis, and they are
packed separately. Fasten the antenna radiator to the antenna unit chassis as follows:

3.4 Heading Alignment
You have mounted the antenna unit faci ng str ai ght ahead i n the di r ecti on of the bow . T her efore,
a small but conspicuous target dead ahead visually should appear on the heading line (zero
degrees).
In practice, you will probably observe some small bearing error on the display because of the
difficulty in achieving accurate initial positioning of the antenna unit. The following adjustment
will compensate for this error.
