Before commencing installation ensure you have the correct unit for
your application. Raytheon Marine cannot be responsible for incorrect
operation due to incorrect unit specification. Always state which
model you have when making any communication with Raytheon or a
registered service agent.
The sensor is designed to receive the signals emitted from the satel-
lites in a direct path. Ideally, the antenna unit should be mounted
horizontally in a location that is open and clear of any masts, search
lights, or other structures that could block the line-of-sight reception
of the antenna unit. The height of the GPS sensor is not as important as
the sensor having a clear view horizon to horizon for optimum signal
reception. In fact, the lower the antenna can be mounted and have a
clear view to satellites, the better. The more stable the antenna, the
easier it is to track satellites lower to the horizon.
When mounting the GPS receiver flush to a deck surface avoid areas
where the unit will be walked on or where it may become a tripping
hazard.
The GPS sensor should be separated by at least 3ft (1m) from other
communication antennas and should not be mounted in the direct path
of a Radar's antenna beam.
While planning the location for the receiver, consider finding a
convenient pathway for running the interconnecting cable which will
connect the GPS receiver to the GPS display unit or to the rest of an
integrated system. Ideally the cable should be run in a manner so that
it can be 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 much as possible to prevent interference
pick-up.
Mounting on the mast of a sailboat is not recommended
