Abstract

A CATV & MoCA splitter has an input and at least one output that is “CATV & MoCA” and at least one output that is “MoCA only.” The splitter functions as a building block to provide a customizable installation that supplies the needed number of “CATV & MoCA” outputs and the needed number of “MoCA only” outputs. The splitter includes a housing with first, second and third coaxial ports attached to the housing. In one embodiment, the second coaxial port is connected to the first coaxial port via a power divider so that all frequencies presented to the first coaxial port can pass to the second coaxial port, and vice versa. A high pass filter, which passes only MoCA signals, connects the power divider and third coaxial port.
