The 6211LP/HP are a series of lowpass and highpass filters that are factory assembled networks, consisting of channel deletion filters and custom designed lowpass and highpass filters. The combination results in a "brickwall" filter eliminating blocks of channels while preserving adjacent channels of interest. The primary applications include deleting blocks of channels for re-insertion purposes, while maintaining the integrity of close adjacent channels. These networks allow for maximum use of existing cable spectrum. The operating temperature for the 6211 series is from 13 C to 33 C.
