Tip
It is sometimes difficult to identify the opposing site. For this reason, it is sometimes
helpful to have someone at the opposing site use a reflecting device, such as a hand-held
mirror, to reflect sunshine towards you. The Giganet optical viewfinder can help in
initial antenna alignment.
6. Insert the azimuth spindle (J) into hole (K) and tighten in place.

7. Mount Giganet optical viewfinder on the antenna (optional). Locate the
opposite site through the viewfinder and loosely tighten the bolts.
8. Attach the ODU to the mount assembly using the four latches on the
ODU (L). See the following figure.
Warning
To verify proper sealing, confirm existence of a rubber O-ring on the
antenna, as shown in the following figure.
Setting Polarization
Polarization is determined by the orientation of the ODU. If the handle of the
ODU is facing up or down then the polarity is vertical. If the handle of the
ODU is to the side then the polarization is horizontal.
Tip
For easy installation and best weather immunity, mount the ODU so that the connectors
are facing down.
