Signal Directors
Signal directors are used in the High Gain Dual and Low Gain Dual system amplifiers only. One
signal director is required per amplifier to route and/or split forward RF signal to the Auxiliary output
port(s). The signal director is available in splitter, DC-8, or DC-12 configurations for splitting the
Auxiliary path signal to feed both Auxiliary ports, or as a jumper for routing all signals to a selected
port.

Note: The GainMaker plug-in signal director produces loss in the forward signal path only. The signal director
is physically located inboard of the forward/reverse diplex filters in the forward path of the amplifier. Therefore,
there are no reverse path losses associated. Auxiliary port reverse input pad values must be selected
accordingly during system design when using the splitter, DC-8, or DC-12 signal director in a station.

System Trim
A plug-in system trim may be used to counter the frequency response effects of some passive
devices in the coaxial plant. A mid frequency, single dip trim (Model MSD-1NGF) is available for all
870 MHz GainMaker amplifiers. The System Trim part number is 714446.
