2.4.3.4. SU Antenna Alignment
Antenna alignment can be done with GigAccess™ Unit Manager software tool. The tool runs on
PC with Windows operating system. In general, low gain antenna (such as omni antennas) do not
required alignment due to their very wide radiation pattern. High gain antennas have a narrow
beam width and therefore require alignment procedure in order to optimize the link.
Instruction hereunder can be done after completion the connection of the AU and SU outdoor
units to their indoor Outlet.
Please perform the following steps in order to align the antenna:
1. Attach data cable from the PC to the SU Indoor Outlet data port. It is possible to attach
special provided cable marked “data only” to a vacant Outdoor Unit port.
WARNING! Do not attach standard CAT 5 cable from the Outdoor Unit directly to the PC.
Connecting the PC directly to the Outdoor Unit may cause damaged to the
Ethernet NIC in the PC.
2. Start “GigAccess Unit Manager” application.
3. Press on the “Start Session” button (“S” symbol)
4. Select the SU from the popup address window
5. Select “Installation” at the left menu tree
6. Rotate the antenna until you get maximum RSSI with minimal PER shown on the right bars
see the installation window in the Unit Manager Tool (Figure 10-3).
WARNING! Do not stand in front of transmitting antenna. Rotate the antenna from the rear side.
7. Secure the antenna by fastening the mounting screws.
2.4.3.5. Antenna Polarization
The SU antenna polarization must be the same as in the AU antenna. In most applications, the
preferred orientation is vertical polarization. Above ground propagation of the signal is better when
it is polarized vertically. To verify antenna polarization, refer to the assembly instructions supplied
with the antenna set. (The polarization of integrated antenna is marked on the backside).
2.4.4. Sealing
The outdoor unit must be sealed against rain with the rubber grommets.
