RN2483 LoRa® - If the RF signal pin is not used, does it require any termination?

If the connection RF signal for a low band and pin 25 is not required, is it OK just to leave it disconnected, or does pin 25 require an electrical termination?

If you don't use the lower frequency band (433 MHz) in your application, it won't be switched on, thus so you can leave this pin open.
