Tier trap filter to block a small band to enable one or two channels with own content (channel S16 & S17). The HSF 265 blocks the frequency range of 251 up to 293 MHz to make frequencies 265-279 MHz free for other use. The blocked frequency range is in the DOCSIS band of Ziggo (former Ziggo regions). This means the filter blocks a part of the internettraffic of Ziggo. We recommend to use two HSF 265 in a row to ensure the best result. See the wiring diagram for the correct installation. Also available in a version with other usable channels (channel S30 & S31) with a blocked frequency range in the DOCSIS band of the former UPC regions (HSF 374: article number 695004729).
