Checking LED Activity
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 f r om the W eb UI Configuration>APs>Antenna Properties
view, or from the CLI using the antenna-property command. Determine the appro-
priate gain for your antenna by checking the following chart.
