The ODUs, are designed for direct antenna attachment via a 9500 MXC-specific
mounting collar supplied with the antennas.
ODU polarization is determined by the position of a polarization rotator fitted
within the antenna mounting collar (the ODU installed such that there is correct
waveguide port alignment between the ODU and its antenna).
A remote ODU mounting kit is also available as an option. These may be used to
connect an ODU to a standard antenna, or to a dual-polarized antenna for
co-channel link operation.
The ODU assembly meets the ASTME standard for a 2000 hour salt-spray test,
and relevant IEC, UL, and Bellcore standards for wind-driven rain.
ODU Data
There are two ODU options:
• ODU 300ep
• ODU 300hp
Both share the same RAC profiles, which means they operate to the RAC 30V3,
RAC 40, RAC 3X and the IDUs.
• Within their band limitations the ODU 300ep and ODU 300hp are over-air
compatible.
• ODUs are fixed for Tx High or Tx Low operation.
• ODUs are frequency-band specific, but within each band are capacity
independent up to their design maximums. Main ODU performance
characteristics are summarized in Table 4-1.
