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