5.7.1.4. Finely Adjusting the Direction
Step 1: Horizontal direction
As shown in Figure 5-41, loosen the hexagonal socket head bolts (a) and (b) securing the
mounting bracket and swing the antenna left or right. Adjust the antenna direction so that the
receive level indicates the maximum value, and finger-tighten the bolts (a) and (b).
Step 2: Vertical direction
As shown in Figure 5-42, loosen the hexagonal socket head bolts (c), (d), (e) and (f) securing
the mounting bracket and tilt the antenna up or down. Adjust the antenna direction so that the
receive level indicates the maximum value. Tighten the bolts at a point showing the maximum
receive level (tightening torque: 8.5N•m).
Tighten the bolts in order of (f), (d), (e) and (c) and make sure that the point showing the
maximum receive level is maintained. This concludes the procedure for vertical-direction
adjustment.
Step 3: Horizontal direction
Finely adjust the horizontal direction by slightly loosening the bolts (a) and (b) again. Once
again, locate the point where the receiving level reaches the maximum value and hold that
point. Finally, tighten the bolts (a) and (b) (tightening torque: 8.5N•m) while making sure that
the point showing the maximum receiving level is maintained. This concludes the procedure
for horizontal-direction adjustment.
The figures show examples of horizontal polarization setup.
