and distribution amps. With the pre-amp, i'll be adding a piece of
hardware to the antenna, and then plugging something into the wall
inside my house that will run current up the coax to power the amp?
Is that how it works?
Yes. The power supply for pre-amps generally run 12-20V up the coax to the
amp mounted on the antenna mast.
