2.7.3 C-Band Outdoor Unit
The C-Band ODU is mounted on the feed support arm of a wide variety of parabolic
antennas ranging from 1.2 to 3.1 meters in diameter. The ODU interfaces other
components by two coaxial cables. The C-Band LNA, OMT, and feed horn assembly are
mounted at the focus of the antenna. The ODU directly interfaces to the IDU.
Refer to Table 2-33 for C-Band ODU specifications.

Note: Excluding any center point of any connector.
The unit will pass data without SYNC loss at 64 kbit/s, QPSK 1/2
rate when subjected to a shock of 10g’s at 10 sec (half sine) on x,
y, and z axes. The unit will survive a shock of 40g’s at 10msec on
x, y, and z axes in non-operating mode.
Note: Without mounting cradle.
