Pointing
After entering the installation parameters, you can begin the process of pointing the
antenna at the satellite. Using the proper azimuth, elevation, and tilt coordinates
obtained from the LUI, you will point the antenna in the general direction of the
satellite to obtain initial acquisition of the satellite signal.
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 SQF of the
received SNR pointing signal appears on the DAPT2 display as a numerical value
from 31 to 255, indicating you are locked onto the correct satellite. This value is
then used to find the peak signal level.
After locating the satellite, you use the fine Az/El adjustment mechanism to
fine-point the antenna using the DAPT2 or DAPT3. 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 DAPT2 or DAPT3 to validate and record the pointing
measurements.
