If no tone is heard, the initial alignment is not satisfactory. It is
recommended to use the Giganet’s optical viewfinder for initial alignment.
In this case, loosen the azimuth bolts, adjust azimuth and tighten in the
position where the highest tone is heard. If this does not help, adjust
elevation and then azimuth. See directions below.
Tip
We recommend that two people perform this installation and alignment procedure, one
at each ODU site, with some method of communications between them.
3.9.14.1. Azimuth Alignment
■ Loosen the nuts shown in the following figure and rotate the antenna
and mount, pointing it to the location of the opposing antenna.
■ Slowly sweep the antenna in azimuth using the azimuth adjustment
nuts.
■ If the desired signal is not found, increase or decrease elevation setting
and repeat the azimuth sweep.
