Do
not
attempt to point the antenna manually by pulling on the feed support
arm. This can cause permanent damage to the antenna. Instead, use the
antenna mechanical adjustments.
You may
gently
maneuver the antenna reflector to coarsely point the
antenna, but only if the Az/El canister bolts are loose enough so that the
reflector rotates easily.
When the demodulator locks onto the satellite beacon signal, the signal quality
factor (SQF) of the received signal-to-noise ratio (SNR) pointing signal appears in
OASIS as a numerical value from 15 to 255. This value is then used to find the peak
signal level. OASIS also displays the target SQF and the maximum SQF attained.
Once the signal level is peaked, you lock the antenna in position.
Registration
After the antenna has been pointed and peaked, you complete the installation
process by using the Registration workflow in OASIS to validate and record the
pointing measurements. See the
OASIS User Guide (1040630-0001)
Entering installation parameters with a wired laptop
After completing physical installation of the satellite modem, connect a laptop to
the satellite modem and access the LUI using an Internet browser. Enter the
satellite and antenna installation parameters. These parameters include:

Latitude and longitude of the antenna site

Satellite name
After you submit these parameters, the satellite modem enters pointing mode. In
this mode, the LUI displays the calculated azimuth, elevation, tilt angle, and antenna
polarization information required for coarse pointing the antenna.
Azimuth measurements are calibrated relative to true north, not magnetic
north.
