Offer the ODU (with pre-fitted mounting bracket) to the bracket strap
and affix using the captive M8 bolt. Tighten to ensure the assembly
grips, but can be adjusted on the pole.
Adjust the elevation and azimuth of the unit to achieve an approximate
visual alignment (does not apply to connectorized ODUs). Tighten both
bolts to the required torque settings of 14 Nm (11 lb ft).
Connect the ODU ground cable to the to the supporting structure
grounding point, within 0.3 meters (1 ft) of the ODU bracket and on the
same metal (if necessary, remove paint and apply anti-oxidant
compound first).
CAUTION
Do not attach grounding cables to the ODU mounting bracket bolts,
as this arrangement will not provide full protection.
To prevent corrosion and possible loss of ground continuity,
weatherproof the grounding point.
