Adding in your own private analog TV channel to your TV Antenna signal - UHF RF modulator

- Adding in your own private closed-circuit analog cable TV channel to your TV Antenna signal - UHF RF modulator. Some recent viewer questions prompted me to re-visit this handy little UHF TV modulator I reviewed a couple of years ago. It turns out that it will pass through a digital over-the-air (OTA) TV antenna signal just fine, preserving the HD broadcast picture. An antenna can be combined with the video/audio from any RCA (AV composite) line-level (also known as baseband) source to make your own in-home cable TV channel, playing your own content on one or more TV's in your home (with the use of a coaxial splitter).

I remember installing one that was a transmitter on uhf analog. It was one of the early ones and it would transmit a hundred feet!
I wonder if this could be used as a low power analog transmitter just by attaching a small whip antenna to the RF output?
It can but many countries don’t allow that.
@@NorthcoasterHobbyTrue, it's probably not "Part 15" compliant.
@@NorthcoasterHobbycan this setup be added to a home security system self monitoring?
@@robertshade8631 Possibly. You could connect a camera signal to the modulator and view your camera on a UHF TV channel.
@@NorthcoasterHobby I’m going to try that because my diy home security system has experienced frequent video loss.I have been unable to determine the source.
Is there a tool to convert digital TV frequency signals to analog? so that analog tube TV can directly read that frequency signal, or is there a similar tool?
The best bet is to use a digital converter box. It receives a digital signal and converts it to analog out on channel 3 or 4 from the coaxial RF out port.

@@NorthcoasterHobby nahh man, it's the same as using an STB, I want it to directly change digital TV signals to analog like old TV which still broadcast analog, so 40 channels can be changed directly from the tube TV remote, maybe there's no equipment for that 😅, because it has to be decoded also
@@YYG_K I think you’d need a whole system of modulators to make that happen. Sort of what they would do for a hotel or hospital.
I picked up several of this type for a reasonable cost. They were advertised as "digital" but that meant that the channel number was digital.... Doh! Oh well, waiting for the real digital ones to come down in price. Could be waiting a while.
The digital ATSC modulators are very expensive. I like the nostalgia of an analog TV channel.
I’m going to get this thing and then put it on my I2jr.
Was just told be Spectrum installer, they no longer use and are not allowed to use distribution amps of any kind. I asked what if customer has many splits and need amplification, he said no. They just ajd. gain on pole feed. I guess it's on customer to get their own amp?
I guess. Here in Canada I have a relative who subscribes to cable. They were having signal issues (5 TV’s) and the technician was able to solve the issue but said he would install a ‘booster’ (presumably an amp) if problems persist. Depends on the company I suppose.
This modulator is for use with over the air TV signals, not cable however.
Maybe they are afraid of leakage, poor shielding or this guy didn't know what he's talking about too. I have 10 splits fairly equal and need 15db maspro amp at source to offset 3.5db loss per split and all is good. Using roof RCA 705ANT. Installed roof beacon on top flashing red for a novelty.@@NorthcoasterHobby
I'm new about this. Can i plug in my Satelite box into this device at downstairs, and then tune the channel on my TV upstairs without cable attach? Where will the RF in and out attach to? All to satellite box?
It’s not wireless. The RF out attaches to a coaxial cable that connects to a TV. Then it tunes to a specific channel on the TV. How will you control the satellite receiver from upstairs? You’d need a remote extender for that.
In general all frequencies work but I observed that if you connect your modulator to you antenna on RF IN port on some frequencies you may have interferences on RF OUT. For example if you use it UHF frequencies especially from 790 - 862 MHz the picture look terrible uue to 4G LTE and my antenna has a filter built ,on 82.25 MHz same problem beacuse of FM broadcast, even on VHF High Band 174 - 230 MHz For North America you may have problems also on VHF Low Band. Also never select a frequency where a digital channel is already broadcasting otherwise you will get nothing, so it is better to select a frequency from midband: 112 - 174 MHz or hyperband: 240 - 470 MHz. But if there is no antenna connected all frequuencies work fine. This is what I tested on European RF Modulator.
My analog modulator is a DIGITQUEST RF STEREO MODULATOR it has the full frequency band: 48 - 862 MHz. It can work everywhere in the world, the default sound mode is B/Gfor most countries, but if you want to use it in North or South America you should switch to M/N, for China is D/K and for United Kingdom, South Africa is I. Suport all video formats, PAL, PAL60, NTSC, SECAM.
I mentioned in the video to select a frequency that is not being used for broadcast.
D/K also for Mongolia, Kazakhstan, Russia, Ukraine, Czech Republic, Poland, Vietnam, also K in French overseas and former French colonies in Africa.
System J/M for Japan, South Korea, Taiwan, Myanmar, and the Philippines.
I'm sure there's a HDMI in version, or ethernet from a camera, but maybe not.
There are.
I hope you can test the atsc 3.0 GT media device it's only 60$.
I’m looking into it. I don’t have any NextGen TV stations here. I see you got one. What do you think about it?
How waas your experience with this particular modulator? I'm thinking about getting this one cause my current has really awful sound
@@mrowa_wn I have had no problems with it at all.👍
You said that “I would suggest get an uhf modulator that gives you more channels than that” in other video but you got 1 channel. Why? You had always 3 channels.
I meant that the UHF modulator gives you a wider range of UHF channels to modulate to, ie: channels 14 and above. Whereas most modulators sold only modulate to VHF channels 3 or 4.
Cool
Is there a way to remotely use this in one location and send through internet connection to another location? Example to eatch my local channels in another state when working on the road
Not that I’m aware of.
Is it possible to link multiple modulators through the rf inputs and end up with a single output signal?
Or do you have to use a splitter/combiner?
You could use a combiner (called a diplexer), or get a modulator like this to make 2 or 3 channels:

@@NorthcoasterHobby Thanks for the reply :)
I bought one of these but there’s no sound output. The sound works if you connect the RCA cables directly to a TV but not the coax from the modulator
@@owensanto4004K Check the sound carrier frequency. It might be on the wrong setting.
@@NorthcoasterHobby thank you so much! That worked
@@owensanto4004K 👍
Looking at the RF frequency chart/code table, those display codes actually match the channel numbers and frequencies for System I (UK, Ireland, Hong Kong, etc): en.wikipedia.org/wiki/Television_channel_frequencies#United_Kingdom,_Ireland,_Hong_Kong,_Macau,_Falkland_Islands_and_Southern_Africa
I've no idea why they'd do that, but at least it does NTSC!
Makes sense, thanks for clarifying this!
Also PAL-M (Brazil), and PAL-N (Argentina, Paraguay, Uruguay). NTSC-J works fine for Japanese UHF TV frequencies, tested with VGA TO VIDEO CONNECTED WITH HDMI TO VGA
2:07 the same thing they switched from analog to digital and then from standard definition to high definition?
The HD broadcast channels will pass through the modulator with no issues. The analog to digital transition took place in the US in 2009.
@@NorthcoasterHobbywhen in the us digital channels were created it was standard definition but then it was high definition.
@@LuckyMTS Digital channels can be standard or high definition.
What device are you using to make RUclips videos? I think you have a iPhone.
@@LuckyMTS Yep.
Can you use portable lcd tv?
@@LuckyMTS Yes.
@@NorthcoasterHobbyyou made that video back in 2021.
@@LuckyMTS The difference between this video and that video is that in this video I showed how to connect the TV antenna so that the modulator combines your TV antenna signal along with your modulated channel, as opposed to using a separate diplexer to combine the signals. I felt that was something I neglected in the first video so I thought I would revisit.
