RF Modulator Question

[Thread7]

I want to send the screen from my computer to several TV's in my house. I picked up a cheap RF modulator and set it to channel 3 and it works. However, whenever I have the yellow video cable plugged into the modulator, it blocks all my CATV channels (digital and analog). Any suggestions on what I need to get for this to work? (Different modulator, diplexers, splitters, notch filter, etc.)

Thanks.

Better modulator that can be set to a channel not occupied by a cable channel. Can't use a notch filter as cable box data and high-speed internet work on the channels below channel 2.

You might have to go above channel 100 to find a clear channel.
