1.1 Antenna Unit
Mounting considerations
• 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.
(a) On bridge (b) Common mast (c) Radar mast
• 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.
MOUNTING
Figure 1-1 Mounting methods
• 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.
• T o 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, 2.15 m, Steering compass, 1.60 m.
• Do not paint the radiator aperture, to ensure proper emission of the radar waves.
• The signal cable run between the antenna and the display unit 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
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:
1. For the XN20AF, XN24AF, attach two guide pins to the underside of the an-
tenna radiator.
2. Remove the waveguide cap from the radiator bracket. The cap may be discarded.
3. Coat the waveguide flange with anticorrosive sealant as shown in Figure 1-2.

4. Coat fixing holes for the antenna radiator with anticorrosive sealant.
5. Grease the O-ring and set it to the O-ring groove of the radiator flange.
6. Set the antenna radiator to the radiator bracket.
7. For the XN20AF, XH24AF, coat hex bolts (M8X40, slotted washer head, 8
pcs.) with anticorrosive sealant and use them to loosely fasten the antenna
radiator to the antenna unit chassis. For the XN12AF , coat hex bolts, flat washers and spring washers with anticorrosive sealant and use them to loosely fasten the antenna radiator to the antenna unit chassis.
8. For the XN20AF, XN24AF, remove two guide pins (inserted at step 1), and
then tighten fixing bolts.
CAUTION
Be sure to remove the guide pins.
Injury may result if the guide pins loosen
and fall.

Fastening the antenna unit to the mounting platform
The antenna unit may be assembled before hoisting it to the mounting platform.
However, do not hoist the antenna unit by the radiator. Always hoist the unit by its
housing. When using a crane or hoist, hoist the unit by the hoist rings which should
be fastened to the bolt fixing covers of the antenna housing.
CAUTION
DO NOT hoist the antenna unit by the
radiator; lift it by the hoist rings. (Be sure to
remove rings after hoisting the antenna unit.)
Hoist

1.2 Display Unit
Before mounting the display unit
If Gyro Converter GC-8 (option) is to be used, install and setup the GYRO CONVERTER Board before mounting the display unit, because of the difficulty involved
in doing it after the display unit is installed. Instructions for installation and setup of
the board are in Chapter 4.
Mounting considerations
When selecting a mounting location, keep in mind the following points:
• Select a location where the display unit can be viewed and operated conveniently and where the screen can be viewed while facing towards the bow.
• Locate the unit out of direct sunlight and away from heat sources because of
heat that can build up inside the cabinet.
• Locate the equipment away from places subject to water splash and rain.
• The display unit is very heavy. Be sure the mounting location is strong enough
to support the weight of the unit under the continued vibration which is normally
experienced on the ship. If necessary reinforce the mounting location.
• Determine the mounting location considering the length of the signal cable between the antenna unit and the display unit. (The signal cable comes in lengths
of 15, 20 or 30 meters; maximum 100 meters).
• Leave sufficient space on the sides and rear of the unit to facilitate maintenance. Also, leave a foot or so of “service loop” in cables behind the unit so it
can be pulled forward for servicing or easy removal of connectors.
• A magnetic compass will be affected if placed too close to the display unit.
Observe the following compass safe distances to prevent deviation of a magnetic compass: Standard compass, 1.40 m, Steering compass, 1.05 m.

4. "Initializing" appears during restoring. It takes about 90 seconds to restore the
default settings, after which the normal display appears.
3.3 Adjusting Video Signal Level
When the signal cable is very long, the video amplifier input level decreases,
shrinking target echoes. To prevent this, confirm (and adjust if necessary) video
amplifier input level.
1. Connect an oscilloscope to TP6 on the INT Board (03P9252) in the display
unit.
2. Transmit on the 12 nm range.
3. Adjust R21 on the INT Board so the value of TP6 is 4 Vpp. (For remote display, adjust R134 on the INT Board.)

3.4 Heading Alignment
You have mounted the antenna unit facing straight ahead in the direction of the
bow. Therefore, 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.
