RAK831 and antennas
Hello, I see that the RAK831 has one SMA and 2 IPEX connectors, marked TX_DEV and RX_DEV.
Can I remove the default SMA antenna and connect 2 external antennas to TX_DEV and RX_DEV
or do I need to do some modification on the board for this kind of setup?
Then you may need to modify the capacitance of the two places：
