22 i3/i4 Satellite Antenna System – Install and User Manual
Adjusting the LNB Skew Angle (Linear polarization only)
LNB Skew Angle
The LNB skew angle only needs to be adjusted when the target satellite uses
in linear polarization. In order to receive the maximized satellite signal level,
the LNB skew angle must be adjusted according to the calculation of current
GPS location and target satellite.
It needs only to be adjusted when changing from satellite to another, or when
the boat has traveled a significant geographic distance. It should NOT need
to be readjusted if the boat stays in the same location and is operating on the
same satellite.

Polarization of your Intellian i3/i4 antenna must be accomplished manually by
the following steps.

and feed horn.
