Receive cabling

In the reverse path, the receive signal from the main antenna of each sector is connected to the A-input of the Receive Multicoupler (RMC) through the receive port of the duplexer of that sector. The diversity antenna connects directly to the B-input of the RMC. Distribution of the reverse path frequencies is accomplished by RF splitters within each RF frame.

Table 3-14 lists the connection between the RMCs and the RF splitters in a 60° STSR Metrocell with two RF Frames. Table 3-15 lists the connection between the RMCs and the RF splitters in a 60° STSR Metrocell using four RF frames.
