INSTALLATION AND SETTING
1.4 Rev. E
1.2.3 Interaction with sea and false echoes
Considerations of interaction with the sea imply that the radar antenna should
be only as high as necessary to clear major objects, and as high to be
consistent with other requirements regarding acceptable horizon and target
detection range. The location of the antenna should minimize sea clutter
returns and the-number of multi-path nulls.
1.2.4 Cables and grounding
The cables and the grounding should comply with the following:
Cable screens, especially coaxial cable screens, should be installed in
accordance with manufacturer's documentation.
The cables should be kept as short as possible to minimize attenuation of the
signal.
All cables between antenna and radar System units should be routed as directly
as possible, consistent with consideration for other equipment, in order to
reduce electromagnetic interference effects. Cables should not be installed
dose to high-power lines, such as radar or radio-transmitter lines.
Crossing of cables should be done at right angles (90°) to minimize magnetic
field coupling.
All outdoor installed connectors should be waterproof by design to protect
against water penetration into the cables.
Cables and microwave transmission lines should not be exposed to sharp
bends.
Cables and microwave transmission lines should be installed with sufficient
physical separation, as defined in the manufacturer's documentation.
