Sorry, but the CM0707 is not an amp, it is a power supply for the original 7777 and 7778 preamps. More exactly, it is a power supply/power inserter.

There is no amplifier shown in the circuit diagram, only a power supply and power inserter. The power inserter is in the upper right corner, consisting of inductor L and capacitor C2 which allow the power for the preamp and the TV signals to share the same coax line to the preamp mounted near the antenna.
