 === Receive (RX) Chains ===
-There are 2 receive (RX) chains connected to the USRPs at all times. No filtering is done on the RX chains, so any frequency can be monitored provided it is within the specifications of other system components (900 Mhz – 6 GHz for large node sector, 1.7-6 GHz for medium node). Only the connections to the USRP 2974 have low-noise amplifiers (LNA) connected due to the low maximum input power raing (-15 dBm) of the USRP N310 receive chains and the close proximity of the TX and RX antennas. All the RX2 ports of the USRPs are connected to the receive antennas as follows:
