Update: I can not change the antenna ports. They are soldered to the board. So I have to buy an adapter. I have Black Pearl with RPA-SMA male(with the pin) and Immersion Rc Fatshark 5.8ghz Antenna Set V2 SMA-male. Is there any way possible to remove the antenna port(RPA-SMA) on Black Pearl and insert RPA-SMA female? Or do I have to buy an adapter?
