• If the above condition cannot be satisfied, separate the sensor so that the horizontal
angle to the interfering object is less than 10°. Refer to the table below to determine
minimum separation distance.
CONDITION 2: Locate the GS-100 sensor out of Inmarsat and radar beams
• Locate the GS-100 more than 20° above the top of a radar antenna.
• Separate the GS-100 at least three meters from an open-type radar antenna.
• If the GS-100 absolutely cannot be separated at least three meters from an open-
type radar antenna, install it at least 80 cm above the top of the radar antenna.
• Separate an Inmarsat B antenna from the GS-100 at least three meters.

More than 20°
CONDITION 3: Locate the GS-100 sensor away from communication (VHF, etc.)
antennas
Separate the GS-100 as far as possible from communication antennas.
