5 Modify the Radio Antenna Type as follows:
•
If attaching quad port antennas, configure all four RF ports with the same antenna type.
•
If attaching triple port antennas, configure ports 1, 2, and 3 with the same antenna type and
configure port 4 (non-active port) to No Antenna.
•
If attaching dual port antennas, configure ports 1 and 2 with the same antenna type and
configure ports 3 and 4 (non-active ports) to No Antenna.
•
If attaching single port antennas, configure port 1to the selected antenna type and configure
ports 2-4 (non-active ports) to No Antenna.
6 Modify Radio Attenuation as follows:
•
Add any attenuation (dBm non-negative) due to cable loss or attenuator added to the line
between AP port and the antenna.
•
Same attenuator loss is assumed and is required for all 4 ports of the radio except when one or
more ports is not connected to the antenna and is properly terminated as describe in next step.
•
The professional installer is responsible for accurately configuring port Attenuation. Never
configure port attenuation higher than the actual attenuation between the AP port and the
antenna.
7 Install a terminator (rf 50 Ohm) on all ports where an antenna is not connected.
