Installation
54-0159 Rev. G
•
The antenna unit should not be too high off the
water (a height above the waterline no more than
half the vessel length).
•
Make sure that the mounting surface is rigid so
that it cannot flex when the vessel vibrates. If
necessary, add a strength member to the mounting
site to stiffen it.
Radar Concerns
The TracVision antenna must be kept out of line with nearby
radars, as their energy levels may overload the antenna’s front-
end circuits. In an ideal installation, the antenna is mounted four
feet above and four feet away from the radar (measured from the
center of the antenna dome to the center of the radar).
The best placement for the TracVision antenna is above the radar.
However, if there will be a significant horizontal separation
between the radar and TV dome (i.e., at least 8 to 10 feet), the
TracVision antenna can be placed below the radar as there will be
little chance of signal blockage.
