Prevent RF Radiation Exposure
Select a location that is well above any areas accessible to
passengers and crew to reduce the risk of RF radiation
exposure. (See
for an illustration of the hazard
area.) If mounting the antenna near an accessible area is
unavoidable, you may configure one or two no-transmit
zones to prevent transmissions in hazardous directions.
(See
“Set Up No-Transmit Zones (Optional)” on page 23
for details.)
Minimize Satellite Blockage
The antenna requires a clear view of the sky to transmit
and receive satellite signals. The fewer obstructions, the
better the system will perform.

Prevent Electromagnetic Interference
To prevent the antenna from interfering with any
electromagnetic-sensitive compasses or equipment,
maintain a minimum distance of at least 5 ft (1.5 m)
between the antenna and any compasses.
Avoid RF Interference
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:
•
Mount the antenna as far away as possible from the
radar and high-power radio transmitters.
•
Do not mount the antenna at the same level as the
radar. Most radar transmitters emit RF energy within an
elevation range of -15° to +15°. Therefore, mount the
antenna outside this elevation range and at least 10 ft
(3 m) away from the transmitter.

IMPORTANT!
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.
IMPORTANT!
Never place the antenna in the beam path of the radar
regardless of distance. Radar energy may damage the
antenna or impair its performance.
