Call for Price

These filter series’ consist of a combination of “brickwall” channel deletion components and lowpass (or highpass) components. Each combination results in a “brickwall” lowpass (or highpass) filter assembly for adjacent QAM channel operation.

The primary application is to delete an existing group of contiguous channel programs for the purpose of reinserting new programming (i.e. – cameras, educational programming, etc.), while preserving adjacent QAM channel programming.
