1.2 Examples of installation
lhen several antennas are installed
on the same mast and 2 or more
antenna may request the highest
position.
The best position at the top of
the mast may be given to a loop
antenna for direction measprement
in the HF range since is is vul—
nerable to resonance

examples. Dotted figures are

Antenna Cable
.1 Note for cable setting
Pay following attention to install antenna cable.
Cable is processed and shipped to a specified length when ordered. Avoid to
cut or extend cable. When cable length should be changed. keep the length
of two lines the same. at least within 10 mm.
Cable: RG— 5 8 A/U twin cable
(or. R G —- 5 8 A/'U armored twin cable)
Plug : BNC-P-55U plugs and ll-203-P plug,
Protect cable from heat. leld flange and others before setting cable.
Pay special attention for welding when cable has been set.
Protect cable from mechanical damage. lhen mechanical damage is anticipated.
Protect it with steel or plastic pipe. Otherwi'se. use a‘rmored cable.
Keep enough separation from cables for communication antennat radar cable or
power cable. Lay cable in metallic pipe, e. g. in steel mast, whenever
possible as shown in figures on this page.
Avoid to extend antenna cable in the air or along stays or wires,

Determine the position of main unit /,
with attention to following conditions. 150 mm ur more
(1) Select a suitable location for
the main unit to avoid direct
sunshine, water splash, high Front "'
temperature and strong vibration
(Z) Ample space for operation and
maintenance and good ventilation
as shown on the right is recommended
(3) Keep good separation from noise
sources such as radio transmitter
inverter. radar. eta
(4) Hanging installation to ceiling is
also possible. Use a plate with
enough strength to reinforce the
ceiling so as not to drop the unit

Power connection
Connect to a DC source 10 V ~ 16V. liinus side is grounded inside the main
unit.
Avoid higher voltage or the main unit may be damaged.
Other power source should be specified at the time of order and DC adapter
or AC power source should be used (option)

3 Grounding
Grounding influences to the sensitivity and noise suppression and hence.
good grounding is required to the hull for steel ship with shortest dedicated
grounding line (KIV copper belt, 30mm wide and 0.5 mm thick) and ship grounding
terminals are required.
In case of non—metalic ship, FRP or wood. provide a copper plate, 300 mmx
450 mm or larger at the bottom of ship for grounding.

Recommend to use following Antenna Cable depending on required length
in order to avoid from attenuation.
Antenna Cable: Twin Coaxial Cable
16m or shorter: RG—58A/U
l7~29m : 5D-2V
30m or longer : 8D-2V
Remark: When using 5D-2V or 8D-2V. additional joint cables for both
Cable ends are required as those have langer diameter than
that of RG58A/U.
