5.3 Installing the GPS Receiver

The Raystar 120 GPS Receiver is designed to receive the signals emitted
from the satellites in a direct path. Ideally, the unit should be mounted
horizontally in a location that is open and clear of any masts, search
lights, or other structures that could block line-of-sight reception of
signals. The height of the GPS Receiver is not as important as it's having
a clear view horizon to horizon for optimum signal reception. In fact, the
lower the unit can be mounted and have a clear view to satellites, the
better. The more stable the unit, the easier it is to track satellites lower to
the horizon.
The Raystar 120 can be mounted on a pole. Alternatively, you can use the
supplied surface mount kit.
When mounting the GPS Receiver flush to a deck surface, avoid areas
where the unit will be trodden upon or where it may present a tripping
hazard.
When planning the location for the unit, consider finding a convenient
pathway for running the interconnecting cable between the GPS
Receiver and the display unit or to the rest of an integrated system. Ideally
the cable should be run such that it is hidden from view and, if possible, be
in a direct path to the point of connection. It is important to keep the cable
separated from other shipboard cables as far as possible to prevent
interference pick-up.
Note: Mounting on the mast of a sailboat is not recommended.

could result in cable damage.
3. Screw the supplied brass studs (2) into the underside of the GPS
mounting surface for fixing and, using the template supplied in this
document, carefully drill the two 6mm (0.25in) fixing holes marked.
