6.4 Mounting surface
A horizontal, solid and steady surface is very important. Make sure that the
surface does not have any irregularities!
Furthermore, please take into consideration that the weight of the antenna unit
is 40 lbs. (18 kg) or more. Therefore, the surface has to be strong enough to
carry the antenna unit, even during the most challenging maritime conditions.
6.5 Planning the cable paths
Before starting the installation, you should check which walls are suitable and
if existing openings can be used for the cables.
All openings have to be sealed in order to avoid any water penetrating.
The control unit should be placed as close as possible to the receiver. The
maximum length of the cable is 3 meters. Refer to Appendix E for data con-
cerning appropriate cable types.
6.6 Power supply
The antenna unit can be connected directly to any ship’s power supply net of
12/24/32 volts DC. The circuit fuse should be rated for min. 5 amperes and
max 7.5 amperes! (See appendix G “Technical Specifications”).
The power distributor must be idle while working on the ship’s supply net
or you may short circuit the system.
If the negative side of the supply voltage of the antenna unit has no connection
to the boat ground, make sure a potential compensation between boat ground
and the ground point of the antenna unit is made.
6.7 Drillings
To avoid any damage to the mounting surface it is recommended that you
start out with drilling a smaller hole, using a 3.5-4 mm bit before drilling the
correct hole size. Use an 8.5-9 mm bit to drill 4 mounting holes for the M8
screws included. To drill the holes in the correct positions, please refer to the
included template.
