I don't think there are 2 transmitters too. They would have to transmit
simultaneously and that would mean interference on the receiver side. So
the transmitter is switched to the antenna which had the better signal
during the last reception period. That is the best choice because usually
the signal quality for one antenna doesn't change very fast.
