Connects to one of the MRAU REV SECONDARY ports (1 - 3)
via CATV cable.
2 RF SMA cable
(1)
50 RF SMA-to-SMA cable
Connects two RF bands together when there is only one
N-type connector on the RAU.
For cases when there is an N-type connector for each RF band
(700MIMO or PCS/AWS), there will not be an SMA cable.
3 Antenna port(s) 50 N-type connector Connects to an antenna. See Table 3 on page 10.
4 SECONDARY FWD connector F connector port Connects to one of the MRAU FWD SECONDARY ports (1 - 3)
via CATV cable.
(1) The 700 MIMO SRAU does NOT have an RF SMA cable; it has two Antenna ports.
