Hello Ifran,

https://docs.nordicsemi.com/bundle/ug_nrf21540_ek/page/UG/nrf21540_DK/hw_rf_measure.html

You connect the RF from your radio to the TRX pin with a cable and then select which ANT1 or ANT2 pin you want to have the amplified signal out on. Maybe I'm not understanding your question correctly, so please share what sort of kits you have and what you are trying to do.

Best regards
