5. INSTALLATION
This chapter covers installation. Installation
mainly consists of the following:
• siting and mounting the display unit and
the antenna unit
• connection of the signal cable and the
power cable
• establishing the ground
• connecting optional equipment, and
• adjustments.

5.1 Antenna Unit Installation

Mounting considerations
When selecting a mounting location for the
antenna unit keep in mind the following
points.
• Install the unit on top of the wheelhouse
or on the radar mast on an appropriate
platform. It should be placed where there
is a good all-round view with, as far as
possible, no part of the ship’s superstruc-
ture or rigging intercepting the scanning
beam. Any obstruction will cause shadow
and blind sectors.
• Locate the unit at least two meters away
from a direction finder antenna to prevent
interference to the direction finder.
• In order to minimize the chance of pick-
ing 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. Ob-
serve the minimum compass safe dis-
tances to prevent deviation of a magnetic
compass:

and power boat are shown in Figure 5-1.
