Is this expected ?
Missing 20dB sounds like maybe you have the other antenna port
selected. Have you tried swapping antenna ports or using a call to
set_rx_antenna() to explicitly select your antenna port?

Also, the USRP2 has no VGA in front of the ADC -- the only gain control
you have is the WBX itself, which is a total range of 31.5dB, AFAIR.
