Adjacent Ch. Suppression Filter


These filters are used to prevent a single DTV channel from interfering with adjacent DTV channel(s) reception.

Utilizing “High Q” components, the model 3271AB fully suppresses the undesired channel without degrading adjacent channels.


  • Typically provides > 20 dB of isolation between adjacent DTV channels.
  • Ideal for use in those “fringe” receive areas where adjacent channel signals co-exist (e.g. translator sites).
  • Broadband Performance – Receive all other DTV channels VHF (2-13) & UHF (14-51) – excluding the undesired channel.
  • Available in Plate Mount or Rack Mount configurations.
  • Standard – 75 ohm impedance with F Female connectors.
    Optional – 50 ohm impedance with N, SMA or BNC F Female connectors.
