Several spare protective caps are provided.
2.2.1 Setting the Skew Angle
(European
Systems Only)
The Antenna LNB skew angle must be adjusted to optimize
channel reception. Refer to your satellite service provider for the
proper skew angle for the selected satellite service and
geographical location.
Adjusting the LNB Skew Angle
1. Turn off the power to the Antenna Unit.
2. Remove the radome and set it aside.
3. Loosen the two wing screws securing the LNB
within the choke feed as illustrated in Figure 2-5.
4. Refer to the LNB skew angle labels on the end of
the LNB and on the LNB choke feed (pictured in
Figure 2-6) 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.
