10.2.3 Sensitivity of the Alignment Adjustment
When performing the RF alignment of the antennas it cannot be over emphasized that you must
rotate the adjustment nut(s) 1/10
th
of a turn at a time between taking RSL readings (allow time for
the RSL reading to update). Table 10-3 shows how many degrees the antenna will move when the
adjustment nut(s) is rotated through one full turn. Error! Reference source not found.Table 10-1
shows that the beam width of the typical antenna is often less than the amount of movement available
with one full turn of the aiming adjustment.
