Aligning the antennas
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™ 1000-AIND unit to the external antenna. The opera-
tional link is shown in
11. Configure WinLink™ 1000™ NMS at both sites to operate at the pure
channel frequency found in the RF survey. WinLink™ 1000™ is now
ready for operation.
Configuring the Link
1. Run the Installation Wizard in the RADWIN Managerr Software to set the
configuration of the link. Configure the link in accordance with the
parameters calculated in the Link Budget Calculator.
2. WinLink™ 1000™ has a unique identification number, the Link Name.
Each side of the link looks for its partner with the same Link Name.
Therefore both sides of the link must be configured with the same Link
Name.
3. The WinLink™ 1000™ 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™
1000™ link is the following:
There are cases when there is no line of sight, but still the link is of an
acceptable quality.
Troubleshooting
If the link is not within the acceptable limit as defined in the previous sec-
tion,

Link, check the following:
Verify that both antennas have the same polarization (horizontal/
vertical).
Check all the WinLink™ 1000-AIND cable connectors for faulty con-
nections.
Verify that there are no obstacles in the Fresnel zone of the antenna
path such as large buildings, trees, etc.
Use a spectrum analyzer with suitable sensitivity to measure the sig-
nal at the distance between the sites.
If nothing improves the receive power level, check the overall link.
