Audio/Video RF Modulator with Antenna Pass-Through

For years, RF modulators have been a popular option for distribution of audio and video signals within homes and businesses. Since the transition to DTV, modulators have fallen out of favor due to misconceptions about the new technology. Televisions with built-in ATSC tuners have the capability to scan the entire TV spectrum, searching for signals in the cable TV and UHF bands.

Commonly treated like an off-air broadcast, a locally generated RF signal can be tuned and stored into memory in televisions connected to an RF distribution system. RF modulators can still be an option for distributing audio and video from surveillance systems, commercial CCTV systems, cable and satellite receivers, and DVD or video game consoles.

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.

Asked by: oldermongrel
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.
Asked by: Hurkeybird
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.

Intended Usage?

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?
Asked by: noobster
Yes, but you still need to run a cable to the other TVs in your house with a splitter/amplifier.
