Note: * for an explanation of possible cause and their remedies refer to
the following paragraphs
1. Blown fuse, low power or wiring
Check that the in-line quick blow fuse (if fitted) has not blown or the circuit
breaker has not tripped. Replace fuse with one of the same type and rating.
If you have extended the power cable from the antenna unit, check that
there is no power loss. Check the system wiring and connections.
2. Satellite signal blocked
Satellite signals can be blocked or degraded by buildings, other boats or
equipment on your boat. Check to see if the antenna has a clear view of
the sky.
3. Outside satellite coverage zone
Your system will provide excellent reception within the antenna coverage
area for your satellite television service. However, signal quality may
degrade as you approach the edges of this zone.
4. Radar interference
The energy levels radiated by radar units can overload the antenna a
front-end circuits. Make sure that your antenna is installed as described in
page 8; ‘Selection of Installation Site’.
5. Incorrect or loose RF connectors
As part of the regular maintenance recommended by Intellian Technologies,
Inc., all connections should be checked to ensure that they have not
become loose. A loose RF connector can reduce signal quality.
6. Multi-switch interference
If you have multiple satellite receiver (IRD) connected to your system,
make sure that you are using an active not passive multi-switch.
