Before you begin, consider the following antenna
installation guidelines.
• 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.
• Consider the distance between your antenna
and any radar. KVH requires that you do not
mount the antenna on the same level as the
radar, because the radar’s energy may
damage the LNB. Most radar transmitters
emit RF energy within an elevation range of
-15º to +15º (see Figure 4). Therefore, mount
the antenna outside of this elevation range
and at least 3 ft (1 m) away from the radar.
• Make sure the mounting surface is wide
enough to accommodate the antenna’s base
(see Figure 5). Also make sure it is flat, level
(within ±1°), strong enough to support the
antenna’s weight, and rigid enough to
prevent antenna vibration.
• Select a location that is as close as possible to
the intersection of the vessel’s fore-and-aft
centerline and midships.
• Be sure to mount the antenna near enough to
the TV-Hub to allow you to connect the 100 ft
(30 m) coax cable between them, while still
maintaining sufficient slack in the cable.
NOTE: If you need to use a longer cable, use a RG-11
(75

) cable that does not exceed 200 ft (60 m) in
length (see “Prepare the RF Cables” on page 7 ).
Be sure to follow the guidelines below.
Damage caused by an improper installation is
not covered under KVH warranty.

Never place the antenna in the beam path of

energy may damage the antenna or impair its
performance.
