1. A filter circuit having a frequency response, the filter circuit comprising:

  • a pass band filter portion disposed along a signal path between a provider-side port and a user-side port, the pass band filter portion configured to pass a provider bandwidth comprising a spectrum of frequencies carrying media content, and attenuate a home network bandwidth comprising an open spectrum of frequencies carrying personal data content; and

    only one multipath interference mitigation leg operatively branched from only the user-side port of the signal path and terminating to a ground, the only one multipath interference mitigation leg configured to decrease multipath distortions in the home network bandwidth by improving a return loss characteristic at the user-side port;

    wherein the frequency response is characterized by an insertion loss characteristic between the provider-side port and the user-side port, the insertion loss characteristic being less in the provider bandwidth than in the home network bandwidth;

    wherein the frequency response is further characterized by the return loss characteristic at the user-side port being more than 10 decibels (dB) in the home network bandwidth; and

    wherein the open spectrum of frequencies in the home network bandwidth is distinct from and is higher than the spectrum of frequencies in the provider bandwidth.
