The TW-4400-HD is a dual LNB launch amplifier. It works as equally well in 950 to 1450MHz dual distribution systems asit does in dual wideband and Ka/Ku 250-2150 systems. Signals may feed both halves of the amplifier. Each amplifier output can work independently from each other to provide a 30 dB max gain. Power may enterthe amplifier from “Out A” or ”Out B” port. TW-4400-HD includes an external DC plug-in supply to power the amp locally. Unregulated power passes to the LNB inputs to enable trunk line power.
