Abstract:
The present invention concerns an apparatus for protecting a satellite reception system from strong terrestrial signals. A high Q tunable trap is used to help reject strong ATSC signals or other signals that may be present on the input coaxial cable of a satellite receiver that operates in a single-wire multi-switch (SWM) environment.
