Aligning connectorized antennas
When aligning antennas deployed with a connectorized ODU, it may not be possible to
hear the alignment tone emanating from the unit. In this case it may be necessary for a
second installer to assist in the operation. Alternatively, it may be possible to extend
the tube on the supplied stethoscope to give a longer reach.
NOTE
Fine antenna alignment can sometimes be achieved by tightening and
loosening the bolts on either side of the antenna mounting bracket, rather
than trying to turn the whole bracket on the mounting pole.
CAUTION
Finally tightening the antenna mountings may cause the antenna alignment
to be altered, due to distortion in the mounting bracket caused by action of
tightening. It is recommended that the installation tone be left turned on
(armed) during this process so that any movement can be noticed and
counteracted by tightening the other side of the bracket.
Aligning dual polar antennas
The procedure for aligning dual polar antennas is the same as that for aligning
integrated units, as described in
