6.6.2 Procedure for Aligning Directional Antennas

After setting up the equipment, follow these steps for aligning directional antennas connected to the
bridging access points. At each location, a technician performs the procedure. Align one antenna
first, and then align the other. As the technicians position the antenna and run the RF Link Test,
they need to communicate with each other using two-way radios or cell phones. Other equipment
you may need is covered in 6.6.3: Additional Suggestions on Antenna Alignment.
1. Attempt to point the antennas toward each other so that the access points communicate with
each other through a wireless access point operation. Information on verifying the wireless
access point operation is covered in 6.3: Preparing for the RF Link Test.
2. Make sure the Rate Control on the RF Configurations screen is set to
rates (Figure 6-15). This is recommended for access points that are performing a bridging
function.
3. If antennas are over a mile apart, set the
the appropriate distance setting. Type in the closest whole number in miles that matches the
distance between antennas. This setting allows for the timing delays for distances over 1 mile.
