C 14-1 Channel Elimination Filters CEF-750

     The CEF-750 is a professional quality, channel elimination filter. This filter is designed to remove one 6 MHz wide television channel, permitting another channel to be reinserted onto the now vacated channel. Attenuation of greater than 52 dB can be obtained on both visual and aural carriers with only negligible loss to adjacent channel carriers. This results in clean removal of any channel (50 to 312 MHz) and provides a means for substituting local origination or a desired channel for an unwanted channel. The CEF-750 is housed in a single height, 1.75" high, rack mountable, aluminum chassis and is completely bidirectional, allowing the input and output connections to be interchanged.
