RDL-2000 Installation Guidelines

When the alignment sweep has been completed, the measured RSSI value should be

checked against the estimated value obtained from the link budget. If the wireless link is

LOS, the measured RSSI value should be within 5 dBm of the calculated value.

A lower or fluctuating RSSI value may indicate that the antenna is aligned to a sidelobe.

If the RSSI value is much lower than the link budget prediction, this may indicate an

optical LOS or non-LOS path. If the link is non-LOS, a suitable reflecting surface such as

a building or billboard must be used. For non-LOS deployments, it is necessary to install

the link and perform vertical and horizontal sweeps of the antenna to determine if the

required throughput can be achieved.

When the alignment is complete, tighten bolts to 13.5 n-m (10 ft-lbs). Tighten each bolt

in a cross-pattern to minimize shifts in the antenna alignment.
