4x3-1, 2, 4 Reverse Configuration Module with Auxiliary Reverse RF
Injection
Signals from the right side of the amplifier (Ports 4 and 5/6) are combined and
routed to a reverse transmitter (XMTR 4). Signals from Port 1 are routed to XMTR 1.
Signals from Ports 2/3 are routed to XMTR 2. An RF signal from an external source
can optionally be injected at Ports 3/6 and coupled with the reverse RF input from
Port 1 and routed to XMTR 1.
Install modules as follows:

Transmitter dedicated to Port 1 in XMTR 1

Transmitter dedicated to Port 2/3 in XMTR 2

