Plan the Antenna Installation
2
Before you begin, consider the following antenna
installation guidelines:
• Minimize blockage. The antenna requires a
clear view of the sky to transmit and receive
satellite signals (see Figure 2). The fewer
obstructions, the better the system will
perform.
• Make sure the mounting surface is wide
enough to accommodate the antenna's base
(see Figure 3). Also make sure it is flat, level,
strong enough to support the antenna's
weight (60 lbs, 27.2 kg), and rigid enough to
withstand heavy vibration.
• Select a location that is as close as possible to
the intersection of the vessel's centerline and
midships.
• Select a location that is well above any areas
accessible to passengers and crew to reduce
the risk of RF radiation exposure.
• Do not mount the antenna at the same level
as the radar because the radar's energy might
overload the antenna. Ideally, you should
mount the antenna 4 ft (1.2 m) above the
radar, outside the beam path of the radar.
• Avoid placing the antenna near any other
onboard antennas to prevent potential
interference.
