1. A radio frequency (“

  • RF”

    ) signal amplifier, comprising;

    an RF input port;

    a power divider network having a plurality of active RF output ports;

    an active communications path connecting said RF input port to said plurality of active RF output ports, said active communications path including an upstream diplexer, a downstream diplexer and a power amplifier between said upstream diplexer and said downstream diplexer;

    a first filter functioning as a MoCA rejection filter and coupled between said power divider network and said RF input port;

    a passive RF output port;

    a passive communications path connecting said RF input port to said passive RF output port; and

    a MoCA pass filter coupled between a first node and a second node, wherein said first node is located upstream of said passive RF output port along said passive communications path and the second node is located downstream of the first filter along the active communications path, the MoCA pass filter configured to pass signals in a MoCA frequency band and to not pass signals in the upstream and downstream frequency bands of a service provider.
