Is it possible to use both the antennas of USRP as receive antennas? For  
example TX/RX should work on frequency f1 as a receive antenna and RX2  
should work on frequency f2 as another receive antenna. Also, USRP  
should  
be able to collect data from both the antennas simultaneously. How can I  
approach this problem

Thanks and Regards,  
Sumedha
