2.8 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.
Adjusting the LNB Skew Angle
1. Turn off the power to the antenna unit.
2. If the radome is not already removed, 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 2-18.
4. Refer to the LNB skew angle labels on the end of
the LNB and on the LNB choke feed (shown in
Figure 2-19) and adjust the LNB as necessary to
match as closely as possible the skew angle
provided by your service provider.
5. Retighten the wing screws.
6. Reinstall the radome. Align the three radome
screw holes with the baseplate nut holders, insert
the #10-24 screws and tighten. Install a protective
plastic screw cap over each screw.
