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 3-8 lists the connection between the RMCs and the RF splitters in a 120° STSR Metrocell with one RF Frame. Table 3-9 lists the connection between the RMCs and the RF splitters in a 120° STSR Metrocell using three RF frames.
