Installing Above Deck Unit (ADU)

Chapter 4. Installing Above Deck Unit (ADU)

4.1 General Requirements

4.1.1 Tower Construction Requirements

The antenna is designed to be installed on a cell tower, mostly monopole type but some lattice or guyed

towers or buildings are also in consideration. To accommodate the antennas, the antenna tower must

satisfy the following requirements:

• Ensure that the construction of the tower consists of sturdy, weatherproof, and non-corrosive material

(e.g. stainless or galvanized steel construction pipe).

• The recommended mounting height of the antennas is about 6m above the ground level and each

antenna will, desirably, be mounted approximately 1 m out from the pole.

• Make sure that the tower is free from any substance which may prevent a good electrical connection

with the antenna.

4.1.2 Antenna Mounting Requirements

You need to procure or fabricate a suitable mounting plate and tower to support the ODE (Outdoor

Equipment).

Consider the following factors to select the mounting method:

• The physical size of the unit (770 mm (30.31 inch) high by 730 mm (28.74 inch) diameter)

• The weight of the unit (30 kg, 66.13 lbs)

• The mechanical resonance of the system excited by: wind induced vibration (5 Hz)

• The system operates in primary-secondary mode. To mount dual antennas on a single tower, ensure

there is <100 ft separation between domes.

• The preferred installation orientation is East to West.

• Ensure the antenna is levelled ±1° in elevation and ±5° from the True North axis.
