Feed Adjustment  (Polarity tuning)

1.  Adjust the Feed to the appropriate skew angle
using the provided scale reference.

NOTE:  Refer to the chart below for polarization
angle.  Elevation and polarity are both dependent
on site azimuth and the difference between satel-
lite and site longitude.

NOTE: Some satellites have a slant angle with re-
spect to the satellite belt angle. Contact the satel-
lite operator for details.
