Plan the Antenna Installation

2
Before you begin, consider the following antenna
installation guidelines:
• The antenna must be mounted outside the
radar's beam pattern.
IMPORTANT!
Do not mount the antenna at the same level as
the radar because the radar's energy will
overload/damage the antenna's LNB.
• Minimize blockage. The antenna requires a
clear view of the sky to receive satellite TV
(see Figure 3). 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 4). Also make sure it is flat, level
(within ±1°), strong enough to support the
antenna's weight (61 lbs (28 kg)), and rigid
enough to withstand vibration.
• Select a location that is as close as possible to
the intersection of the vessel's fore-and-aft
centerline and midships.
• The antenna must be located within 100 ft
(30 m) of the ACU.
