hi @endnode, thanks for your answer.

No, this is not supported out of the box, you can get only simple LOW/HIGH GPIO signal before/after radio event which might work well for Power Amplifier or Low Noise Amplifier (therefore this feature is called PA/LNA). However all nRF5x chips have only single radio peripheral HW block and single antenna input. You can see it pretty clearly in the specification as well as several Q&S on this forum (e.g. here). You can still probably use that to control multiple RF switches because you should be able to fork that PA/LNA signal through PPI to multiple GPIO ports. However there is no example so it's up to you or your FW developer.

(also it's questionable if your solution with 4 directional antennas is better then two or even one omnidirectional antenna but I hope you have that modeled and measured...)
