Audio/Video RF Modulator with Antenna Pass-Through
I just got one of these. If the antenna is connected, the channel created from my CCTV DVR goes away. I had to connect an old cable-antenna switch, and you have to do only one or the other. I have a rooftop antenna with an amplifier.
In this case, your "CCTV" channel is likely the same as or too close to the frequency of one of the off-air channels. Try setting the modulator to an alternate channel.

Distribute CH 2-69 and a/v modulated signal at same time
I want to connect my over the air antenna and y/w/r a/v to the rf modulator and have it transmit both the ch 2-69 & ch 4 signal at the same time since the rf output will go to 2 bedrooms and I person may want to watch the modulated signal in 1 bedroom while the person in the 2nd bedroom wants to watch the regular TV channels. Will your modulator do this. The one I have now blocks the antenna input whenever the yellow rca cable is plugged in and it's feeding device is turned on.
It's worth a try, but generally, this series of modulators is designed for a "through put" of one signal at a time. These are good units--cost effective and send a good signal, but at a show site, they can be a handful. And a bedroom is every bit like a show site. You can always get a second unit and "Y" the inputs to both if the one is not flexible enough. The pro units are expensive.

Do I understand this to mean I could output my cable box to this unit and send the signal other tv's in the house without the need for additional cable boxes?
Yes, but you still need to run a cable to the other TVs in your house with a splitter/amplifier.
