Chapter 3 • Pointing the antenna by using the DAPT3
1039429-0001 Revision D
A SQF value of 31 or greater indicates acquisition of the correct satellite
beacon.
16. Wait for the SQF reading to settle on a value then use the appropriately sized
wrench for the specific antenna to adjust the antenna azimuth and elevation.
See the guide specific to the antenna you are installing for in-depth
instructions about making these adjustments.
Continue until you achieve the highest possible SQF value.
Note: The tone from the DAPT3 will be louder and the cadence will quicken
as the beacon is acquired.
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.
17. When the signals are peaked, tighten the azimuth and elevation bolts
completely.
Note: Because slight movement of the antenna occurs during lockdown,
always measure the signal peak value after locking down the antenna.
Registration
Important: If the BUC uses an external power supply, at this point you must
reinstall the modem with the Enable TX Voltage checkbox
unchecked on the input parameters screen. See step 11 of
Entering installation parameters on page 28. Once you have
reinstalled the modem, proceed to step 3. If the BUC does not
use an external power supply, continue to step 1.
1. Press Advance (3) for Yes or Toggle (2) to return to pointing validation mode.
If you press Advance (3), the DAPT3 prompts you for confirmation that you
want to save the results, with the message:
