Antenna Gain Recommendations

The OAP180 auto-adjusts the power level sent from the radio to the antenna, so that the
EIRP emitted from the antenna is the value defined by the controller (100mW by default).
You can increase this setting if you are compensating for signal loss from long inexpensive
cables connecting external antennas. (Configure a false/low dBi antenna gain to trick the
radio into supplying more transmit power to that antenna, which would then make up for
the cable loss.) You may also need to decrease the EIRP from 100mW to 30mW for a
device that only transmits at 30mW. The Antenna Gain values can be changed from the
Web UI Configuration>APs>Antenna Properties view, or from the CLI using the antenna-
property command. Determine the appropriate gain for your antenna by checking the
following chart.

Function
When power is applied, this LED initially turns amber, then blinks
green when the system power check is applied, and then is a steady
green when power is on.
The 11bg connection LED blinks amber when radio packets are
being transmitted and when the radio is beaconing. If there is traffic
over the air on this radio, the blinking rate increases.
The 11a connection LED blinks green when radio packets are being
transmitted and when the radio is beaconing. If there is traffic over
the air on this radio, the blinking rate increases.
The Ethernet Link LED blinks green when a link has been detected
and is in use.
