1.2.1 TracVision L3 Components
The Antenna Unit includes the antenna positioning mechanism,
signal front end, power supply and control elements. The
antenna is a parabolic dish mounting a low noise block (LNB)
converter with built-in preamplifier. The European configuration
includes a single port LNB while the North American system
uses a dual-output LNB. 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 from below-decks units.
