Aluminum Case Antenna IDs?

Just for completing the records…

@Karolis, perhaps you could clarify?

Hello, please follow the schematic specs. The table lists frequency ranges for RF IO ports - some of them have different internal matching for lower/higher frequency operation (RX case), where TX can be matched for all operating frequencies.
In Aluminum Case default configuration, the antenna ports are connected to the ports with “lower” frequency matching networks (RX1_L, RX2_L, TX1_1, TX2_1).
