THE
ALIGNMENT PROCEDURE
Performing
the fine-alignment procedure can be a one- or a two-person task
depending on how far the PC is from the antenna. If the antenna is
close enough for the person aiming the antenna to hear the
computer speaker (or if you can connect a remote speaker to the PC
and place the speaker next to the antenna), you can use the tones
generated by the PC as a reference. Otherwise, it is best to have
a second person watch the computer monitor as it displays the
signal strength meter information. If two people are performing
the procedure, one person can view the computer monitor and
provide feedback to the person aiming the antenna as to how well
the signal is being received.
- Run
Microsoft Windows 95, 98 or Windows NT Workstation on your
computer, click on the Start button, then select Programs >
DirecPC > Antenna Pointing. After a short delay, the
Antenna Pointing screen displays.
- Verify
that the displayed state and city information is correct, then
click on the Next button. The computer displays the azimuth,
elevation and polarization parameters. The signal strength
program starts and the computer beeps steadily.
- Stand
behind the antenna reflector, grasp the outer edges of the
reflector and, while looking at the Alignment Mark, adjust the
azimuth one eighth inch towards the center pencil mark that
you made on the mast in Step 4 (the front of the antenna moves
to the right and the Alignment Mark moves to the left). Let go
of the antenna and count slowly to ten while listening for a
change in tone from the PC. You must provide the DirecPC
adapter enough time to track and register the signal strength.
You are aiming at a target 22,300 miles away. The key to
success is to make small adjustments - never more that one
eighth inch of azimuth as measured on the mast - and to wait ten
seconds between adjustments to give the DirecPC Adapter the time
it needs to lock on to the satellite signal.
- If you
are receiving a signal, go to step 11. If no signal is present
and the alignment mark has not yet moved to the leftmost
pencil mark on the mast, return to Step 8.
- If there
is no signal after the antenna has been moved 1 1/2 inches
from the right most pencil mark to the leftmost pencil mark,
there may be an error, see the note below. If you are
following the "Mast not plumb" instructions in the
note on Page 1, add one degree of elevation and return to Step
5.
Note: If you are still unable to acquire the
satellite signal after sweeping through the full 1 1/2" as
measured on the mast, perform the following quick checks:
- Verify coaxial cable connections at the LNB and along the
cable to the DirecPC Adapter.
- Verify that there are no obstructions blocking the signal
(for example, trees)
- Verify that you copied the azimuth, elevation, and
polarization values correctly and set the elevation properly
on the antenna.
- Verify the azimuth by moving 15 feet in front or behind the
antenna and take another compass reading (metal near the
compass (like a car or even a belt buckle) can give a false
reading).
