Align Antennas

After wireless bridge units have been mounted, connected, and their radios are operating, the antennas must be accurately aligned to ensure optimum performance on the bridge links. This alignment process is particularly important for long-range point-to-point links. In a point-to-multipoint configuration the Master bridge uses an omnidirectional or sector antenna, which does not require alignment, but Slave bridges still need to be correctly aligned with the Master bridge antennna.

•Point-to-Point Configurations – In a point-to-point configuration, the alignment process requires two people at each end of the link. The use of cell phones or two-way radio communication may help with coordination. To start, you can just point the antennas at each other, using binoculars or a compass to set the general direction. For accurate alignment, you must connect a DC voltmeter to the RSSI connector on the wireless bridge and monitor the voltage as the antenna moves horizontally and vertically.

•Point-to-Multipoint Configurations – In a point-to-multipoint configuration all Slave bridges must be aligned with the Master bridge antenna. The alignment process is the same as in point-to-point links, but only the Slave end of the link requires the alignment.

The RSSI connector provides an output voltage between 0 and

3.28VDC that is proportional to the received radio signal strength. The higher the voltage reading, the stronger the signal. The radio signal from the remote antenna can be seen to have a
