Chapter 5. Installing Outdoor Unit (ODU)
5.1 General Requirements
5.1.1 Antenna Mounting Requirements
You need to procure or fabricate a suitable mounting plate and pole to support the ODU (Outdoor Unit).
Consider the following factors to select the mounting method:
• The physical size of the unit (770 mm (30.3 inches) high by 845 mm (33.3 inches) diameter).
• The weight of the unit (About 33.6 kg (74.1 lbs) for Primary or 32.5 kg (71.7 lbs) for Secondary).
• The mechanical resonance of the system excited by wind : 5 Hz
• The system operates in primary-secondary mode. Ensure there is < 20 m (10 m or 20 m Inter-dome cable
kits are available to purchase separately) separation between the primary and secondary antenna.
• The preferred installation orientation is East to West.
• Ensure the antenna is levelled ±1° in elevation and ±10° from the True North axis.
• The mounting method should be able to preserve antenna pointing calibration under wind load and
protect safety of life and safety of property.
