yes, note the following:

* if you receive only, then TX/RX is the receive antenna port.
* if you transmit and receive, then RX2 is the receive antenna port.

the switching is done automatically by the fpga's ATR registers.

yes, same for wbx and rfx series. You can do full duplex.

The main difference as far as antenna switching is concerned is that the
UHD lets you select the RX antenna when doing a receive only. The same
rules above apply when transmitting.
