MATV / RF Filters & Traps

  • MATV filters & traps are NTSC channel / frequency standard, 75 ohms impedance with F-type female connector
  • Customizing is available. Please inquire for other frequency, connector, or impedance standards. Example configuration: PAL / BNC / 50 ohms.
  • Production graphs are provided for many filters & traps to illustrate typical frequency response
  • To refer to CATV or Broadcast channel or frequency - see NTSC Freq. Chart


Used to pass a desired TV channel or segment of TV/RF spectrum (from 40 to 860 MHz) and reject out of band frequencies. Adjacent and semi-adjacent models available.

Attenuation of signal at specific frequency (4 to 900 MHz). Use to suppress an interfering carrier, and other applications. Models available with multiple notches, indoor and outdoor housing.

  • Fixed frequency
  • Trap with switch
  • Tunable notch

Band rejection filters with non-adjacent channel selectivity, designed for off-air antenna systems. Use to attenuate specific TV channel or RF signal band. Typical stopband: specify from 15dB to 30dB.

Back to the top


Designed to pass desired frequencies in lower segment of TV spectrum and reject frequencies in upper segment. Custom specifications available.

Designed to pass desired frequencies in upper segment of TV spectrum and reject frequencies in lower segment.

Combiners consist of individual bandpass filters joined together at common port. Combines multiple single-channel sources into one output, or, separates broadband signal into individual channels: TV & FM

Back to the top


Three port devices consist of a highpass, lowpass joined together at a common port. Combines or isolates two signal bands, e.g., VHF (0-230 MHz), UHF (470-860 MHz)

Injectors consist of a bandpass, bandstop joined together at a common port. Used to network off-air antennas, or combine a single channel with a broadband signal.
