 To align the antennas:
1. Slowly move the site B antenna azimuth axis (the elevation axis
should be locked) until you see the best signal on the SA Lock the
azimuth axis.
2. Slowly move the site A antenna azimuth axis (the elevation axis
should be locked) until you see the best signal on the SA.
3. Lock the azimuth axis.
4. Slowly move the site B antenna elevation axis (the azimuth axis
should be locked) until you see the best signal on the SA.
Lock the elevation axis.
5. Slowly move the site A antenna elevation axis (the azimuth axis
should be locked) until you see the best signal on the SA.
Lock the elevation axis.
6. Repeat steps 1 to 4 until the reading on the SA is equal or as close
as possible to the calculated receive signal (for Rx Power Level, see
Expected Signal Level for AIND radios).
7. When the SA reads the expected receive signal, the antennas are
aligned and there is an indication of a good link between the sites.
8. Tighten the antenna azimuth axis and elevation axis.
9. Stop the CW function. The NMS will restart the system.
10. Connect WinLink-AIND unit to the external antenna. See WinLink™
Installation and Operation Manual for details. The operational link
is shown in Figure 2-1.
11. Configure WinLink™ NMS at both sites to operate at the pure
channel frequency found in the RF survey. WinLink™ is now ready
for operation.
Configuring the Link
1. Run the Installation Wizard in the WinLink™ Manager Software to
set the configuration of the link. Configure the link in accordance
with the parameters calculated in the Link Budget Calculator.
2. WinLink™ has a unique identification number, the SSID. Each side
of the link looks for its partner with the same SSID. Therefore both
sides of the link must be configured with the same SSID.
3. The WinLink™ link is now ready for operation.
Evaluating the Link
With the link operating at a pure channel as determined by the
RF survey procedure, the recommended performance threshold of an
WinLink™ link is the following:
