3-4 | Cyber Hardened IBUC 2, IBUC 2e, IBUC 2G, IBUC R, IBUC G Operations Manual: Installation
Test Equipment
Terrasat recommends the equipment or its equivalent listed in Table 3.1 for
installation and system alignment.
Site Considerations
The ODU is designed to be mounted on or near the antenna. Locate and install the
antenna according to instructions supplied by the antenna manufacturer. Choose an
area that is free of interference from motors or other electrical equipment and that has
a clear line of sight from the antenna to the satellite. Use size 3/0 or 4/0 AWG
(American Wire Gauge) stranded copper wire to ground the Cyber Hardened IBUC 2,
IBUC 2e, IBUC 2G, IBUC R or IBUC G to the antenna frame and to the lightning
protection ground rod. For higher power units with an external power supply, Terrasat
recommends using an isolation filter to reduce power line interference.
Mounting Considerations
Optional mounting brackets are available to aid mounting on most antennas. The ODU
must be mounted such that:
• The IBUC has sufficient support to minimize the effects of antenna sway in strong
winds.
• The fan intake and exhausts are free from any obstructions.
• The heat fins have air movement across them.
Throughout installation and during any polarization, azimuth or elevation adjustment,
ensure that cables and waveguide are not crimped or pinched. Ensure that there is
adequate slack in the cable.
