Each Tailwind 500 system requires an IF Multiplexer Unit (IMU). To equip your
system with HD-receiving capabilities in the CONUS region, an IFMU-1000 and at
least one RDUC-4000 also need to be added to your system’s architecture.
One IMU and one IFMU-1000 are needed per system and can support multiple
RDUC-4000 configurations. Sample block diagrams are available upon request to
provision space and wiring for the IFMU-1000 and RDUC-4000, which are expected
to be available in mid-2019.
