- low pass filter for internet
- Posted by m. lamphier on October 27th, 2004
Anyone recommend a source for buying a low-pass filter to allow cable
internet through (<30MHz or so) but block cable TV (>50MHz or so)? I
can find lots of high pass filters for sale (e.g. Radio shack) but
hard to find sources for low pass. Something designed for cable
TV/internet prefered.
thanks

You don't want to do that. Cable modems operate in two directions, with one
direction below the TV channels and the other at a considerably higher
frequency. If you use a low pass filter, your cable modem will no longer
work.
Why do you want to filter it?

Cable internet service requires both an uplink channel (<40 MHz) and a
downlink channel (330 - 1002MHz, typically around 700 MHz). Digital
cable channels use the 330 - 1002MHz range, as do analog cable channels
42 and higher.
