4.1.4 Dew or Rain Pooling on Dome
Dew or rain can occasionally pool on the top of the radome.
While this moisture will usually be dispersed when the vehicle is
in motion, it can disrupt the signal while the vehicle is at rest.
This issue can be minimized with two approaches:
1. Spray the dome with hosed water to remove the
dew from the dome surface.
2. Periodically apply liquid dish detergent to the
dome surface. Wipe the full-strength detergent on
the dome and allow it to dry. This treatment will
provide a film that will help moisture bead up and
roll off the dome.
4.1.5 Outside Satellite Coverage Zone
TracVision L3 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.
4.1.6 Vehicle Turning During Startup
If the vehicle turns during the 60-second startup and
initialization sequence that occurs immediately after turning
on the power to the TracVision L3 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
TracVision L3 off for at least 10 seconds. Turn the system back
on, making certain that the vehicle is either motionless or
travelling in a straight line for the 60 seconds immediately
following power-up.
4.1.7 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 2.3.6, “Connecting the Antenna RF Signal
Cable to the IRD” for directions on proper Antenna Unit to
RF cabling.
