KVH Industries LF - Manual (Page 9)

1 Introduction
1.1 Digital Satellite Television
DIRECTV ® , DISH Network ™ , and ExpressVu systems transmit
digital audio and video data from land-based transmitters to a
satellite “parked” above the equator. Each satellite relays the
signals in spot beams covering the continental United States.
TracVision LF/SF automatically identifies, locks onto, and
receives signals from the appropriate satellite. TracVision SF is
designed for stationary use only; TracVision LF works while your
vehicle is at rest and in motion.
1.2 System Overview
A complete satellite TV system includes the TracVision LF/SF
connected to an IRD (satellite TV receiver) and a television set. A
desktop or laptop computer is used to conduct diagnostics. The
complete system is illustrated in Figure 1-1. System specifications
and a wiring diagram are provided in Appendices A and B,
respectively.
