4. System Operation
This section describes the operation of the DBS-30500 satellite system. It does not focus on the
operation of the receiver, except where it pertains directly to the operation of the DBS-30500 satellite
system. For questions about your satellite receiver, please refer to the receiver’s operating
instructions.
4.1 Choosing a Location
It is important that your vehicle have an unobstructed view of the southern sky. Trees,
mountains, buildings and other objects can prevent the satellite’s signal from reaching the DBS-30500.
Also, please note that when the DBS-30500 is searching for the satellite signal, the angle at which the
antenna seems to be pointing (perpendicular to the dish) is 23° lower than the actual angle to the
satellite. This is due to the offset of the feed (or LNBF) from the center of the dish, as shown in
Figure 3.
