Make sure to install the antenna with the drain plug side up as shown in the
following figure.
Figure 3-31 Correct Orientation of Antenna
5. Roughly align the antenna with the opposing site. This may be done by
eyesight, using a compass or with the Giganet optical viewfinder.
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.
6. Attach the ODU to the mount assembly using the four latches on the
ODU (L). See the following.
Warning
To verify proper sealing, confirm existence of a rubber O-ring on the
antenna, as seen in the following figure.
Setting Polarity
Polarity is determined by the orientation of the ODU. If the handle of ODU is
facing up or down then the polarity is vertical. If the handle of the ODU is to
the side then the polarity is horizontal.
