Waveguide Directional TV Combiners

Rev : 01 | Rev date : 18 Dec 2020

The narrowband input corresponds to the bandpass resonant frequency, whereas the wideband input can be any other channels in the applicable UHF band. Modules are connected together to provide a multi-channel combiner. The order (number of poles) of the filters will determine the channel spacing required for given channels, and also the mask, if any that may be provided.


Each combiner module features

  • Compact size, small foot print
  • Floor and ceiling mountable
  • Wideband, high performance couplers for plug and play style expandability and flexibility
  • Highest power rating for size/class
  • Lowest loss for size/class in all sizes
  • Temperature stabilized
  • Adjacent channel operation
