Antenna Alignment Tool

point in the approximate direction of the remote SGT-LD-5-23 antenna and assists the user to easily
align the local antenna to achieve maximum signal strength.

To use “Antenna Alignment Tool”, follow the steps below:
Open “Peer-to-Peer Setup” and select “RF1” or “RF2”. Enter the MAC address of the remote
bridge and click on the Apply button. Then click the “Align Antenna” button and the “Antenna
Alignment Tool” window will popup.
Set the target RSSI (e.g. -70dBm) and click “Start” button.
Wait about 5 seconds; the antenna alignment starts and performs alignment every one second.
Fix the local antenna and adjust the remote antenna elevation and horizontal direction. During
the adjustment, observe “Current RSSI” in the local SGT-LD-5-23. The value will refresh every 1
second. Fix the remote antenna when it reaches your expectation. Usually, a RSSI between
-60 and -70dBm indicates rather good signal strength.
Adjust the local antenna after fixing the remote one. During the adjustment, observe the
“Current RSSI” in the remote SGT-LD-5-23. Fix the local antenna when it reaches your
expectation.
During the antenna alignment, the SGT-LD-5-23 will issue beep sound to indicate current RSSI.
Frequency of beep indicate the following RSSI:
