Antenna Alignment
Usually, low gain antennas do not require alignment due to
their very wide radiation pattern. High gain antennas,
including the integral antenna of DS.11 units, have a narrow
beamwidth necessitating an alignment procedure in order to
optimize the link.
Check the antenna alignment by using the RSSI bar on the
bottom panel of the
RB-DS.11 unit.
 To align the antenna:
1. Confirm that the units at both ends of the link are
receiving power.
2. Synchronize the units by aligning the antennas at the
central and remote sites until maximum signal quality is
obtained. Check the signal quality RSSI bar on the
bottom panel of the RB-DS.11. The first LED lights red
to indicate that the unit is working. The remaining nine
LEDs light green to indicate the signal strength. The
stronger the signal, the more LEDs are lit. Rotate the
antenna to the left or right until you reach the point of
maximum RSSI reading. Make sure that at all times the
front of the antenna faces the general direction of the
BU-DS.11.
