CEF-750 Channel Elimination Filter
The Blonder Tongue CEF (Stock Number 4446) is a professional quality, 750 MHz channel elimination filter. This filter is designed to remove one 6 MHz wide television channel, permitting another channel to be re-inserted 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, CH 2-38) and provides a means for substituting local origination or a desired channel for an unwanted channel. The CEF750 has a passband to 750 MHz and is completely bidirectional, allowing the input and output connections to be interchanged.
