2.1 SELECTING THE INSTALLATION

POSITION

1) Physical selection criteria

• Install the antenna at the center of the mast on the keel line.

• If the antenna cannot be installed at the above position for some reason, the amount of

deviation must be minimized. And, reinforce the mount base and the platform and take
precautions to protect the antenna from vibration and impact at the installation position.

• To avoid the radiating section coming in contact with other installed objects while it is

rotating, ensure that there is at least 200 millimeters from the swing circle (turning radius) to
other installed objects (Fig.1). The swing circle of the JMA-5300MK2 radar's antenna is as
shown in Table 1.

• Avoid having a rope or signal flag from winding around the radiating section thereby

preventing it from rotating.

• Avoid the effects of dust and heat caused by smoke from a chimney.

• When determining the appropriate antenna height and installation location, take into

consideration the reduction of vibration, the strength of the hull and the antenna mount base,
and maintenance properties.

• Provide for maintenance space: platform, safety link, hand rail, steps, etc. The lower edge

of a radar antenna should be a minimum of 500 mm above any safety rail.

• When installing the scanner, select a location where there are the fewest structural objects in

the surrounding area so that the capability to drive the motor will not be depressed by the
non-equability wind which is likely to rotate the scanner.

2) Electrical selection criteria

• The installation height of the antenna relates to the maximum detection distance. The

higher, the better. However, if it is too high, radio wave energy greatly attenuates above the
antenna's vertical beam width (the point -3dB from the peak of the main lobe). As a result,
it is difficult to detect a close-in target. Sea clutter also increases. Determine the
installation height by taking into consideration the weight, maximum length of the cable, and
maintenance after installation.

• If the installation height of the antenna is low, it is difficult to detect a long distance target.

The ship's mast, derrick, and chimney interfere with radiating beam causing the range that
cannot be viewed on the radar display to increase.

Generally, the lowest antenna installation position is supposed to be on the A-B line shown in

Fig.2.
In the case of the JMA-5312/5322 type radar, 2θ equals 20°.
In the case of the JMA-5332 type radar, 2θ equals 25°. Specifically, the antenna position is

normally elevated so that the chimney and the shrine-gate type mast do not interfere with

radiating beam.
The A-B line, or L line of sight from the radar antenna to the bow of the ship should hit the

surface of the sea in not more than 500 m or twice the ship length, depending which value is

smaller, for all load and trim conditions.

• If it is considered that sufficient installation height cannot be provided when the antenna is

installed directly on the roof of the wheelhouse, use a mounting rack or radar mast (FIG.3).
Normally, when the antenna installation height is less than 2 meters from the roof of the
wheelhouse, provide a mounting rack assembled at an angle frame to install the antenna.
When the antenna installation height is 2 meters or higher from the roof of the wheelhouse,
provide a cylindrical radar mast to install the antenna. Consider the convenience of the
service staff who take care of installation, maintenance, adjustment, and repair of the
antenna by providing adequate footholds to the mounting rack and the radar mast.

• When installing the antenna, select a location where there are the fewest structural objects in

the surrounding area so that false images which interfere with target detection will not be
generated by signal reflection from other antennas, deck structures, and cargo. Only as a
guide, note that structural objects should not exist within the range of the vertical beam
width (Fig.4).

Vertical beam width of X-band: Approx. 20° (±10.0° when the height of the radiating
section is 0°)
Vertical beam width of S-band: Approx. 25° (±12.5° when the height of the radiating
section is 0°)

Fig.4 Antenna and the surrounding structural objects

• When installing two or more scanners, scanners in close proximity should have a minimum

vertical elevation separation angle of 20 and a minimum vertical separation of 1m where

possible, so that those scanners do not enter each other's vertical beam width range.

Fig.5 Installing two or more scanners

• To avoid interference with other equipment and to prevent radio noise from generating, do

not place the VHF antenna, GPS antenna, and INMARSAT's dome within the range of the

vertical beam width.

• Keep a record of installation height data. The data is necessary for the initial setting of the

display unit.

• Minimize the blind sector, and ensure the adequate view angle so that the blind sector does

not exist in the range 22.5° from side to rear (Fig.6). Specifically, ensure a sufficient view

field in the straight front (relative bearing 000°).

• Individual blind sectors of more than 5º, or a total arc of blind sectors of more than 20º,

should not occur in the remaining arc, excluding the arc in the above condition (Fig.6).

22.5°

Individual blind sectors of more than 5º, or
a total arc of blind sectors of more than 20º,
should not occur in the remaining arc.

• For radar installations with two radar systems, where possible, the antennas should be placed

in such a way as to minimize the blind sectors.

• Magnetron which has strong magnetic force is included in the antenna. Install the antenna

at least 6 meters away from nautical instruments including magnetic compasses and
chronometers.

* If there is a concern that structural objects existing within the vertical beam width may

generate false images, equip the structural objects with a radio wave absorber. (There are
two types of absorbers: broadband type having no specific resonant frequency and
narrowband type which can absorb a band with a specific frequency. Use those where
applicable.) Furthermore, it is effective to install a metal reflector, which reflects radio
waves upwardly, between the antenna and a structural object so that the radar's radio wave
will not directly come in contact with the structural object.

When the structural objects exist in the surrounding area of Scanner unit, the false echo may

appear. The sector blank function is effective to reduce the signal reflection from the
structural objects. Because it can stop transmission. Therefore, it may reduce the false
echo appearance.

Because most radio wave absorbers have poor durability, some must be

Note:

replaced every year. When installing a reflector, the area to the rear of the
reflector becomes a blind sector. Therefore, minimize the size of the reflector.
When the sector blank function set to on, ensure a sufficient view field in the
straight front.

* The above procedures for selecting an antenna installation position are described based on

the radar's antenna. Comprehensively select the antenna position by considering other
antennas' installation procedure manual, hull's structure, strength of the selected position,
and vibration. About compass safe distance, refer to the instruction manual section 11.

3) Confirmation during test run

If the antenna vibrates a lot during test run, try to reduce or prevent vibration by reinforcing

the antenna mount base or using wire stays attached to the radar mast.

4) Others

• The design of the mounting platform for the scanner should take into account the vibration

requirements of resolution A.694(17) and furthermore defined by IEC 60945.

Vibration

Frequency 2 to 13.2Hz

13.2 to 100Hz

Amplitude +/-1mm +/-10%

Acceleration 7m/s2 constant

• All installations should facilitate protection of equipment, including cabling, from damage.

The cables should be kept as short as possible to minimize attenuation of the signal.

• Crossing of cables should be done at right angles(90°) to minimize magnetic field coupling.

2-5

• Eliminating the interference on frequencies used for marine communications and navigation

due to operation of the radar. All cables of the radar are to be run away from the cables of

radio equipment. (ex. Radiotelephone. Communications receiver and direction finder,

etc.) Especially inter-wiring cables between scanner unit and display unit of the radar should

not be run parallel with the cables of radio equipment.

• Cable should not be exposed sharp bends.

• The grounding of equipment units should be carried out according to INSTALLATION OF

SCANNER UNIT.

5) After installation
After you have completed the installation work, make a installation report with your

signature and explain it to the customer, then request him to keep the report on board a ship.

The installation report is now available for download on the our Marine Service Department

website (https://www2.msd.jp).

2.2 INSTALLATION PROCEDURE

1) Precautions for transporting and storing the antenna

• An scanner is a heavy load. Be very careful about handling it.

• Do not allow the scanner fall on its side while it is stored or being installed.

• Do not apply rope to the scanner in the way that squeezes or deforms the radiating section.

• When hoisting the scanner by a crane, do not hoist it by attaching a belt or a rope only to the

scanner's radiating section as shown in Fig.7.

• When lifting the S-band scanner（Fig.8）:

When lifting the scanner with the radiator by a crane, attach a rope (or belt/wire) to four
hoisting eyebolts attached to the scanner's chassis, and then lift the scanner so that a
protector attached on the radiator will be located between the rope and radiator.
Use suitable rope in length so that the distance from the crane's hook to the hoisting
eyebolts will be 2.5m or more.
Use the protector attached on the radiator in factory, an additional protector should be not
used. Because excessive protector will cause damage to the radiator's radome. After
installation of the scanner, remove the protector from the radiator.
If the lifting rope is attached to the scanner's support section located at the bottom of the
radiator, a load is imposed to the joint between the radiator and the chassis, then this will
cause damage.
On lifting the scanner, if the lifting rope (or belt/wire) is short, or a protector is not used, it
will scratch the radiator's radome.
And then, if a thick protector on the radome is used, it causes damage to the radome.

• When lifting the X-band scanner（Fig.9）:

Wrap a cloth around the scanner's support section located at the bottom of the radiator, and
then attach a belt to it to lift the scanner.

2) Installation procedures

a) Maintain a flat level surface on which to install the antenna.

• Use sufficiently thick steel material and reinforcement material for the antenna's

installation surface (mount base) to reduce vibration and impact. Keep the mount base
flat and smooth.

• If there is a partial gap between the mount base and the antenna chassis's legs, work on

the installation surface so that it becomes flat and smooth. If a gap exists and the
antenna is tightly clamped, the chassis will distort and become damaged by vibration.

b) Avoid using vibration-proof rubber and resin

• Do not insert an elastic body, such as vibration-proof rubber or resin, between the mount

base and the antenna chassis' legs. If rubber or resin is inserted, the amplitude of
vibration increases, resulting in the possibility of damage to the antenna. Furthermore,
if installation bolts become loose due to deterioration of rubber or resin, the antenna
may be damaged or fall from its mount.

3) Installation and clamping method

a) Installation direction

• Installation should be done so that the cable gland is oriented toward the stern.

b) Bolts, nuts and tightening torque to be used

• Use stainless steel bolts for the antenna and uniformly tighten all of the bolts using

double nuts for each bolt so that the antenna will not become loose (Table 2).

• Although the length of the bolt will differ according to the thickness of the mount base,

use a bolt long enough so that more than 4 millimeters of thread protrudes beyond the
double nuts after the double nuts have been tightened.

c) Use of washer and corrosion-resistant measures

• At the location where a bolt's head or nut comes in contact with the antenna chassis' legs

and the mount base, insert a plain washer which fits the bolt; and, at the location where
the nut comes in contact with the plain washer, insert a spring washer, and then securely
tighten the nuts (Fig.10).

• To prevent corrosion due to the contacts between different metals, such as the antenna

chassis' legs, installation surface, bolts, nuts, etc., cover the bolt's head and nuts with
sealant (Fig.10).

Fig.10 Use of washer and corrosion-resistant measures

2-9

d) Grounding and corrosion-resistant measures

• Ground the antenna chassis and the installation surface (hull) by using an earth line.

Apply sealant to the connection portion of the earth line to prevent corrosion and
damage by vibration (Fig.11).
