1.3 Direct broadcast satellite overview
Direct Broadcast Service (DBS) satellites broadcast audio, video and data information
from satellites located 22,000 miles in space. A receiving station, such as the Ocean
Line antennas, should include a dish and satellite receiver to receive the signals and
process them for use by the consumer audio and video equipment.
requires a clear view of the satellite to maximize the signal reception.
Objects such as tall lighthouse, bridges and big ship that block this view will cause a loss
of signal. Heavy rain, cloud, snow or ice may also interfere with the signal reception
quality. If the satellite signal is lost due to blockage or severe weather condition, services
from the receiver will be lost (picture will freeze frame and may disappear). When the
satellite signal strength is again high enough, the receiver will resume providing desired
programming services.

Antenna
The antenna unit houses the antenna positioning mechanism, the LNB
(low noise block) and control elements within a radome. Weathertight
connectors join the power, signal, and control cabling from the
belowdecks units.
Control Box
The Control Box is the system's user interface, providing access to the
system and its functions through an LCD and three buttons. It also serves
as the vessel's junction box, allowing the system to use vessel power, and
supply and receive data to/from the antenna unit.
