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 antenna should take into
account the vibration requirements defined by IEC 60945.

• 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.
• Eliminating
the
communications 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 antenna 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 this
manual.
5) After installation
After you have completed the installation work, check and test the
installation work with customer(s) and confirm with each other.
