Selecting a position for the ODU (connectorized)
Mount a connectorized ODU in a position that gives it maximum protection from the
elements, allows easy access to the cables, and allows antenna cable lengths to be
minimized. If separate antennas are being deployed, it is not necessary to mount the
ODU at the mid-point between the antennas.
Mounting the ODU
To mount the ODU, proceed as follows:
1
Attach the ODU bracket strap to the pole using M8 x 40 mm or M8 x 70 mm
bolts, M8 flat washers and M8 coil washers. Tighten to ensure the assembly
grips, but can be adjusted on the pole.
2
Use the integrated lifting eye to hoist the ODU up to the bracket, observing the
safety precautions listed in
Checks and safety precautions

.
3
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.
4
Adjust the elevation and azimuth of the unit to achieve an approximate visual
alignment (does not apply to connectorized ODUs). Tighten all three bracket
bolts to the required torque settings of 14 Nm (11 lb ft).
Do not over-tighten the bolts, as this may lead to failure of the assembly.
