2. 3 Selecting location
This illustration shows the importance of a proper location for the antenna unit.

Note that criteria such as an unobstructed view to the satellite and a strong mounting surface are
met. Furthermore, no sources of interference, e.g. radar equipment or other antennas, such as
mobile communication antennas, should be installed nearby the Marine TV antenna unit. A mini-
mum distance of 8-12 ft. (2-3 meters) has to be observed in order not to affect the picture quality.
Although the radome is sealed, it is recommended to avoid direct waves and bilge water!
The antenna unit has to be installed so that no superstructures will obstruct the sight to the satel-
lite! Please note, that the elevation angle depends on the geographical location of the boat and on
the selected satellite!
☛
Equally important for a good installation are the conditions of the mounting surface and the
lengths of the different cables. See section2.4, 2.5 and 2.6.
2. 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.
2. 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 F for data concerning appropriate cable types.
2. 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 H “Tech-
nical 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.
2.7 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.
