Plan the Antenna Installation
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
“No-Transmit Zones (Optional)” on page 25
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.
Figure 4: Blockage from Obstruction
Prevent Electromagnetic Interference
Maintain a minimum distance of at least 5 ft (1.5 m)
between the KVH antenna and any GPS/GNSS, cellular, or
VHF antennas or other electromagnetic-sensitive
equipment to avoid interference. Also maintain a minimum
distance of at least 1 ft (30 cm) between the KVH 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 transmit frequency/power,
transmitter beam properties, and the reflective properties
of nearby surfaces, consider the following general
guidelines:
•
Mount the KVH 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 5 ft
(1.5 m) away from the transmitter. If mounting the
antenna directly above or below the radar, minimum
distance is 3 ft (0.9 m).
Figure 5: Avoiding RF Interference
IMPORTANT!
The interference guidelines provided in this manual
cannot possibly account for all equipment variables
and vessel conditions. Therefore, KVH recommends
testing the KVH antenna at the chosen mounting
location with the other vessel equipment in operation, if
possible, prior to finalizing the installation. If
interference occurs, relocate the antenna.
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.
