Setting the Horizontal or Vertical Polarization
4.
Place a level on top of the electronics package to ensure that the electronic package is horizontally level.
Loosen the antenna attachment bolts, the pivot bolt and elevation adjustment bolt enough to allow the antenna
to be moved.
5.
Adjust the azimuth and rotate the antenna towards the Node. Fine tune the alignment by sighting the Node
using the grooves in the antenna exterior surface. Make sure the electronic package remains horizontally level.
6.
Tighten all bolts enough to keep the antenna from slipping.
Note:
Final mechanical alignment will be made when all the RTU cables are connected and the power
from the NIU is turned on.
