1.2.1 TracVision Cruiser Components
The Antenna Unit includes the antenna positioning
mechanism, signal front end, power supply and control
elements. These include antenna drive controls and
mechanisms, the cable wrap subassembly, antenna gyro
sensor, power conditioning and regulating circuits, and the RF
detector. The antenna is a parabolic dish mounting a dual port
low noise block (LNB) converter with built-in preamplifier. A
molded ABS radome encloses the baseplate and is secured in
place with standard fasteners. Liquid-tight (watertight) fittings
located on the back of the baseplate join the power, signal, and
control cabling to below-decks units.
1.2.2 Integrated Receiver Decoder
The IRD receives satellite signals from the Antenna Unit for
signal decoding, processing and channel selection, and sends
the signals to the TV set for viewing. Messages are sent from
the IRD to the Antenna Unit and messages are received from
the Antenna Unit for display on the television screen. The IRD
also provides the interface for the user to activate authorization
for reception. Please refer to the User’s Manual provided with
your selected IRD for complete operating instructions.
Multiple IRDs may be connected to the Antenna Unit to
provide satellite signals to a number of TV sets. When two
or more IRDs are connected to the same antenna, an active
multiswitch must be installed between the Antenna Unit and
