Does anyone have a diagram for a basic notch filter that will block out a cable tv channel (3 or 4) so i can insert my own signal into the line for local viewing? Channel 3 or 4 would be the target to get rid of, 60-70 MHz range. I've never made a filter and google searchs have been void from good infomation.
One thing to note, I also have digital cable and a cable modem. I'd like to not tick either of them off ;-). I found the following paragraph about the cable modem's freq's,
"To deliver data services over a cable network, one television channel (in the 50 - 750 MHz range) is typically allocated for downstream traffic to homes and another channel (in the 5 - 42 MHz band) is used to carry upstream signals."
The filter would have to leave
