Antenna Pointing
NOTE: The Reflector contains a 22 degree offset look angle for the 1.0/1.2 and 21 degree angle for the
.90m. Therefore, when the reflector aperture is perpendicular to the ground, the antenna is actually
looking 22 degrees, or 21 degrees for the .90, in elevation. All mount hardware should be firm, but not
tight..
1. Adjust the reflector up or down in elevation by turning the two 1/2” hex nuts at the Clevis until the
desired elevation is measured (taking reading from the face of the reflector).
Elevation of Satellite above horizon = Measured angle from face of reflector minus 22 or 21 respectfully.
2. Azimuth Adjustment: With the electronics set to acquire the satellite, rotate the antenna in azimuth until
the satellite is found. Roughly obtain the strongest signal and tighten the hardware on the Pipe Brackets.
5. Patriot recommends the use of cross pol nulling using a spectrum analyzer during TX/RX installations.
After tightening the azimuth and elevation hardware, peak the co-pol signal using the spectrum analyzer.
Then rotate the feed assemble roughly 90 degrees to obtain a cross pol null. Fine tune the null. The scale
on the feed horn can be used with the tick mark on feed holder top or the seam between feed holder top
and bottom. The tick mark and seam are 90 deg. apart. Note that changes may be necessary to the
resolution and video bandwidth to bring the signal above the noise floor. Note the angle of optimum cross
pol null. Rotate the feed back exactly 90 degrees and tighten the feed clamp.
4. Tighten all mount hardware
NOTE: If signal is not found on first pass of Azimuth, adjust elevation up or down in 2 deg increments until
signal is found.
3. Peak the satellite signal by fine adjustments made in both azimuth and elevation until the optimum
signal is achieved.
Note: With Azimuth hardware snug (loose enough to allow adjustment), turning the Azimuth bolt allows 3
deg fine adjustment.
