Power supply hookup
You will need to have a cable line running back into the house which has a power adapter plug on the end (supplied with amp) which goes into a normal power outlet. In my case I had an unused line going into the basement from the junction box so I just hooked up the power adapter to the end of that cable line which was already near a power outlet.
If you do not have an existing line which can be repurposed then a new entry point through the foundation/wall will have to be drilled and a new line ran.
I did see improvement even by just putting the amplifier inside the house on the line running to my main TV but the maximum benefit comes from improving all lines before the signal splits. In many cases the splitter is inside the house so its easier to attach the power supply line.
