4.1.4 Satellite Coverage Issue
TracVision LF/SF will provide outstanding reception throughout
the entire coverage area for your satellite television service of
choice. However, signal quality can be degraded as you approach
the fringe coverage areas. Refer to your satellite television service
manual to check the viable coverage area.
4.1.5 Vehicle Turning During Startup
(TracVision LF only)
If the vehicle turns during the 60-second startup and
initialization sequence that occurs immediately after turning
on the power to the TracVision LF unit, the antenna gyro will
record that variable motion as “standing still.” This may cause
the antenna to track improperly. To solve this problem, turn the
TracVision LF off for at least 10 seconds. Turn the system back
on, making certain that the vehicle is either motionless or
traveling in a straight line for the 60 seconds immediately
following power-up.
4.1.6 Incorrect or Loose RF Connectors
As part of preventive maintenance (described in Section 5,
“Maintenance”) KVH recommends checking the antenna unit
cable connections. A loose RF connector can reduce the signal
quality. Refer to Section 2.3.2, “Connecting the Antenna to the IRD,”
for directions on proper antenna unit to RF cabling.
4.1.7 Type of Multiswitch Used
An active (not passive) multiswitch must always be used to
connect the TracVision LF/SF system to multiple IRDs. Refer to
Section 2.3.2, “Connecting the Antenna to the IRD,” for directions on
proper multiswitch/multiple IRD cabling.
4.1.8 Stationary Use Only
(TracVision SF only)
The TracVision SF antenna was designed for stationary use only.
As such, the antenna will track the desired satellite while your
vehicle is parked, but not while the vehicle is in motion.
