Selecting a position for the ODU (connectorized)
If the ODU is connectorized, select a mounting position that gives it maximum protection
from the elements, but still allows easy access for connecting and weatherproofing the
cables. To minimize cable losses, select a position where the antenna cable lengths can be
minimized.
Mounting the ODU
To mount the ODU, proceed as follows:
1
Attach the ODU bracket strap to the pole using 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 integral safety loop (Figure 5-1) to hoi
st the ODU up to the bracket,
observing the precautions described in Checks and safety precautions on
page 5-
4.
3
When the ODU is in position, use the safety loop as a fixing point to secure a
permanent safety lanyard from the supporting structure to the ODU, as a
precaution against mounting failure.
4
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.
5
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).
