1. An entry adapter for allowing external signals to be conducted between an external network and an internal client network, allowing client signals to be conducted in the internal client network, and blocking the client signals from being conducted from the internal client network to the external network, the entry adapter comprising:

  • a first port configured to allow external signals to be received by the entry adapter;

    a second port configured to be connected to a subscriber device, so as to allow the external signals to be conducted to the subscriber device;

    a plurality of third ports each configured to allow the client signals to be conducted to the internal client network, wherein the external signals comprise cable television (CATV) signals having a frequency between 5 MHz and 45 MHz or between 54 MHz and 1002 MHz, and the client signals comprise Multimedia over Coaxial Alliance (MoCA) signals having a frequency between 1125 MHz and 1525 MHz;

    a first splitter configured to receive the external signals from the first port;

    a frequency band rejection device configured to receive the external signals from the first splitter and to allow the external signals to proceed from the first splitter to the plurality of third ports, and to block the client signals from proceeding from the plurality of third ports, through the frequency band rejection device, and to the first port;

    a second frequency band rejection device electrically connected to the first port, wherein the second frequency band rejection device is configured to block the client signals from being communicated to the external network;

    a second splitter configured to receive the external signals from the frequency band rejection device, wherein the second splitter is configured to split the external signals from the frequency band rejection device and distribute the external signals received from the frequency band rejection device to the plurality of third ports; and

    a passive signal path extending from the first splitter to the second port, wherein the passive signal path does not extend through any splitters between the first splitter and the second port, such that a strength of the external signal is not diminished between the first port and the second port to an extent that would interfere with communication between the external network and the subscriber device, and wherein the passive signal path does not include any powered signal conditioning components; and

    an active signal path extending from the first splitter to the frequency band rejection device, wherein the active signal path includes one or more powered signal conditioning components.
