FILTER HIGH PASS 258 MHZ

The return path blocker filter is used to prevent interference in the DOCSIS cable modem network. The filter is typically installed at the star point of the antenna network on one or more outputs to prevent noise interference in the DOCSIS 3.1 return path frequency range of 0–204 MHz from reaching the distribution amplifier. This noise can disrupt or block the operation of DOCSIS 3.1 cable modems throughout the entire building or even over a larger area. With the blocker filter, the interference can be confined to a single output, allowing most modems in the building to function properly. After installing the blocker filter, DOCSIS modems will no longer work at the antenna points or in the daisy-chained outlets connected to that output. DOCSIS is a broadband internet connection operating over a cable TV network.
