This unit features two RF input connectors (3 & 4), to allow mixing signals coming from two different systems or subracks. When only one of the two inputs is
used it is advisable to terminate the unused input port with a 75 ohm load (ref 4061). As with all T.0X units, this amplifier is powered via the 24 Vdc power bus.
The unit combines and amplifies input signals in the 54-862 MHz frequency band.
