2.10 Setting the Skew Angle
(European Systems Only)
To optimize channel reception, the antenna's LNB skew angle
must be adjusted. Refer to your satellite service provider for the
proper skew angle for your selected satellite service and
geographical location. You can also find the proper skew angle
from the ADCU, as long as a GPS is providing data to the ADCU
or the vessel's correct latitude and longitude are entered into the
ADCU. Refer to "Antenna Status Data Screens" on page 82 for
details on viewing the ADCU-calculated skew value.
Adjusting the LNB Skew Angle
1. Turn off the power to the antenna unit.
2. Remove the radome and set it aside in a safe place.
3. Loosen the two wing screws securing the LNB
within the choke feed as illustrated in Figure 2-37.
Skew Labels
4. Refer to the LNB skew angle labels on the end of
the LNB and on the LNB choke feed (shown in
Figure 2-38) and adjust the LNB as necessary to
match as closely as possible the skew angle
provided by your service provider or the ADCU.
5. Retighten the wing screws.
6. Reinstall the radome. Align the six radome screw
holes with the inserts in the baseplate, insert the
#10-32 screws and tighten. Install a protective
plastic screw cap over each screw.
