I just bought one of these modulators. You can broadcast on UHF channels 14 to 83. The trick is setting the modulator on channels 65 to 136. This is because channels 14 to 64 on the modulator are the cable channels. Channels 7 to 13 (VHF high) has the best signal if you don't have an antenna booster. For maximum clarity on just about any channel you'll need an antenna on both the TV and modulator along with a booster. I didn't try it on UHF on all channels, but on VHF high 7 through 13 is almost perfect with just an antenna without a booster on the modulator and had just an antenna splitter on the TV in the next room. Picture and sound was slight grainy but still almost perfect. To know what your UHF channel is, you will need to take your UHF channel and subtract it from the channel number on the modulator. That will tell you how many numbers to add to find your UHF channel. Example: If you're on channel 14 UHF your modulator needs to be on channel 65. The difference is "51". Subtract 65 from 51 and that will be your UHF receiving channel which is 14. Same goes if you want channel 83 or anywhere on the UHF analog spectrum. It is 51 from the number indicated on the modulator from 65 on up. Actually if your television goes slightly past channel 83, you would be receiving on channel 84 or 85 UHF; if they really did exist. Channel 134 is UHF 83. 134-51=83. 136-51=85 and 135-51=84. Remember that channels 14 to 64 on the modulator is the analog cable band.

I was able to get my setup to work on VHF Channel 6 because of this video, and now I can watch/listen to anything I want anywhere in my house. Thanks man!
Back before analogue was switched off, the RF in, was for your main antenna, or for the RF output from a VCR to pass-through to your TV. Most would leave that unused today. The modulator's RF out, should connect directly to the antenna socket on the back of the TV inself, though nice it has enough RF power output to work with an antenna transmitting the signal.
That's the real purpose of the device. Plug an antenna into the RF in, plug your camera/DVD player into this device like he showed, then the RFout goes into a splitter with coax going throughout your house. Now everyone can watch that camera you hooked to the modulator on channel 12 anywhere in the house. Daisy chain a few modulators together by running the RF out of one modulator into the RF in of another, and you have a cable system. The fact that you can put the output into an antenna is a happy accident.
Nice. I just picked up a 1978 Panasonic TR-3000p portable tube tv that runs on d cell batteries, going to get this and “stream” video from my tv or video camera. Haha hell yeah
I think you need to connect the antenna to the rf in and rf out connects to your coax throughout your house that connects to the rf input to your tv's. That way you have a good strong signal to the tv. Depending on the signal you might need a fixed attenuator.
also try hooking up an fm transmitter to the rf in on the box using a coax cable to connect the fm out and to uhf box in then use that antenna I suggested in the comments below pretty cool lol
is there a tutorial for this box anywhere? i got it hooked up, but the closest i can get is taking away the static noise from having no signal😅 if it helps i have it hooked up to a RCA AU-097Y portable TV from 1975 directly with a 75 Ohm to 300 Ohm UHF/VHF/FM Matching Transformer Converter.
Im pretty sure the rabbit ears amplify what they pick up, and put out the coax, not what comes up the coax and out the wires. They usually require power too. I would try a pair of plain rabbit ears instead, also extending the antenna on the TV would increase signal too.
Your transmitting on a receive only aerial, the built in amplifier is not meant for transmitting, put a bypass switch so you can use it for transmitting or use a coat hanger
I forgot to mention that with the VHF low band 2 through 6, channel 6 is also 87.7 on FM radio so if you are broadcasting on VHF channel 6; you will also hear the audio on 87.7MHz. Even if you want to use 87.7MHz for FM; from my understanding you will need to have some kind of video signal being that is also on channel 6 VHF low. This modulator will work for both FM and low power TV transmitting in your home if you use channel 6 and 87.7MHz. Just remember that your sending antenna will need to be within the FCC Part 15 limits being it is an unlicensed broadcast. NOTE: If your area uses channel 6 and 87.7MHz by another low power station. DO NOT USE this frequency, even if the signal is weak. It MUST be pure static and snow to ensure no signal conflicts. Some states are using analog channel 6 for FM broadcasting. Not sure how long this will continue.
Isn't the reason you can't get the RF input to work because there aren't any analog broadcast stations in your area? Near downtown Orlando I can get one on rare occasions.
I was trying with the coax off a vcr and it should have worked because it has a modulator for rf just one no where near powerful enough for over the air signals.

After you get one of these you will need an AV to HDMI converter, because these HD modulators only support HDMI, so you have to convert the composite video. These converters are extremely cheap so you don't have to worry about that, the thing is to get the modulator.
