Lennox Hearth G8 - Manual (Page 27)

• The mounting surface should be flat and strong
enough to carry the complete assembly (85 lbs/
38.6 kg). To prevent warpage to the antenna
baseplate, 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.
• Be sure to account for the height and base
dimensions (see
Figure 2-2 on the following page).
Also be sure to leave enough space outside the
access hatch to allow a technician to remove the
seven hatch screws and perform maintenance
through the hatch.
• Maintain at least four feet (1.3 m) separation
between the antenna and any magnetized
materials, large ferrous masses, cranes, engines,
derricks, other antennas, cables carrying high
amperage direct current, or battery banks. Take
extra care when mounting the antenna on a steel
vessel; use an aluminum, brass, plastic, or wood
(NOT steel or iron) platform to position the
antenna at least four feet (1.2 m) above and six feet
(1.8 m) away from the steel surface.
• Be alert for devices that change their magnetic
characteristics when in use, such as CRTs
(computer and TV screens), radar magnetrons,
electric winches, loudspeakers, windshield wipers,
and other devices with DC motors. The antenna’s
internal sensor cannot compensate for changing
magnetic fields created by these devices.
Radar Concerns
The TracVision antenna must be kept out of line with nearby
radars, as their energy levels (from both the main beam and its
side lobes) may overload the antenna’s front-end circuits. In an
ideal installation, the antenna is mounted four feet
(1.2 m) above
and four feet (1.2 m) 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 TracVision dome (i.e., at least 8 to 10 feet
(2.4 to 3 meters)), the TracVision antenna can be placed below the
radar as there will be little chance of signal blockage.
