Reason for Additional Antenna gain in Commissioning file while using Rx DivSharing.
In the RF Module the Rx Signal that is available at the Rx01 port of the RFM is already amplified (+29db) in case of most RF Module Variants. Hence we have a diff of 29db between the Ant1RxM and Ant2RxDiv(in this case-supplied from Rx01 of other RFModule) & we ‘compensate’ this by Informing the SW that there is a gain already in the ANT2 Port !
