I need some advice on using filters with TV modulators. I currently have 2 four-channel modulators in my house for distributing dvd, camera, and HA displays. I have plain old analog cable so I just put a low pass filter at the cable feed that blocks anything above channel 100 from feeding back to Time-Warner. I then use a block of 16 channels (allowing a for blanks between each modulated channel) above channel 100 for my internal stuff.
My question is this: If I someday decide I want to get digital cable, which uses the frequencies above channel 100, where is the best place to move my block of 16 internal channels and what type of low-pass or notch filter would I use to prevent backfeed to Time-Warner yet not degrade the digital channels?
The "technical" folks at Time-Warner had no clue or advice.
