What to do if COMBA Antenna shows DL Input Power Overload Alarm?
If the COMBA Antenna DL Input Power Overload Alarm occurs, test the DL input power of the MU. If it exceeds +32dBm, reduce the source output power or add an external attenuator with a suitable attenuating value.
How to fix COMBA Antenna Over-Temperature alarm?
If the COMBA Antenna experiences an Over-Temperature alarm, ensure the environment temperature is within the supported range (0~40? or -20~50?). For harsh environments, apply climatic protection to the system.
What causes COMBA Antenna DL Output Power Overload Alarm and how to resolve it?
If the COMBA Antenna displays a DL Output Power Overload Alarm, it might be because the output power exceeds the threshold (39dBm for MRU). To resolve this, decrease the gain to reduce the output power.
