You can do this externally by putting in a bias-tee in the RF line prior to input to the USRP. I've personally used the following from MiniCircuits:


Or if you want to take a more risky route, on the DBSRX daughterboard there is header to input a DC voltage. I'm trying to do the same thing (GPS with the DBSRX & USRP), and am not going to risk frying something at this point. Hope this helps.
