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
(within ±2º), strong enough to support the
antenna’s weight (57.6 lbs, 26.13 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.
• Avoid placing the antenna near any magnetic
compasses or other onboard antennas to
prevent potential interference.
Radar/High-Power Radio Transmitters
Although many variables determine the exact
distance required between the antenna and
radar/high-power radio transmitters, including
transmitter beam properties and the reflective
properties of nearby surfaces, consider the
following general guidelines when selecting a
safe antenna location:
• Mount the antenna as far away as possible
from the radar and high-power radio
transmitters.

RF emissions from radars and high-power
radio transmitters may damage the antenna
or impair its performance if it’s improperly
positioned within the beam path.
