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 S3 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 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.
4.1.7 Type of Multiswitch Used
(North American Systems Only)
An active (not passive) multiswitch must always be used to
connect the TracVision S3 system to multiple IRDs. Refer to
Section 2.3.6, “Connecting the Antenna RF Signal Cable to the
IRD”
for directions on proper multiswitch/multiple IRD
cabling.
