Setting the LNB Skew Angle (Linear Versions)
To optimize satellite signal reception, linear TracVision M5/M7
systems require adjusting the skew angle of the antenna’s LNB (low-
noise block) whenever you change your geographic location or change
which satellites are set up for tracking. Before setting the skew angle,
be sure to determine the correct skew angle for your selected
satellite(s).
TIP: Sky Mexico subscribers can also refer to Figure 1-4 on page 8 for the
approximate skew setting for the PAS-9 satellite.
Determining the Skew Angle
Follow the steps below to determine the skew angle for the selected
satellite(s).
1. Connect a PC to the maintenance port, as described in
“Connecting a PC to the Maintenance Port” on page 27.
Then type the following commands in the
HyperTerminal window.
2. Type
