- RF Modulators: Make your own Private Analog TV Channels the Easy Way. Modulators change a video signal to be usable on an RF channel. Normally modulators work on channels 3 or 4, but UHF modulators are also available to give more flexibility and avoid co-channel interference, as I run into in this video. It’s an easy way to play your own content on a closed-circuit TV channel available only to your televisions.

Best video ever. I got everything I needed in less than 30 seconds. Liked the video on one account, switched accounts then liked it again. Good work. Underrated.
Thank you so much for watching! Glad it helps!
Just picked one up at the thrift store for 3.50 and I was not sure what it did. Seems more handy than I thought. I will for sure hold onto it and maybe try these methods out.
Thanks for the great video.
What a great find for $3.50! Thanks for watching!
Excellent video. I remember these Radio Shack RF modulators and I only wish that I had purchased one when they were available here in Australia. Of course, I can do that also with a VCR. So, all is not completely lost.
watching modern videos through an old manky CRT has got to be the most meta shit ever ong
crt's are much higher quality and cooler than new tvs
@wilko9396 I agree. Modern speakers on tv's are junk. Even my 2006 Magnavox HD Flatscreen has 100x better speakers than a new one.
This video brought back to me a lot of nostalgic feelings of the good old 90s
Thanks! I'm trying to do something similar and you even used the same device I'm using, which helped.
Used to be able to descramble "premium channels" using these back in the day lol
I loved Old Systems
great video!!
Thanks for watching!
epic same b/w mini tv i have i have ordered a cheap box modulator and also found i can use some british> digitalbox RF Out to receive the digi box picture with that.
definitely i cant wait to watch some 1944 and 1960s american dramas on my mini tv from my PC
The video carrier of your RF modulator is AM instead of 8VSB that's why it interferes with the lower adjacent channel which means if your RF modulator is channel 3 it interferes with channel 2 as seen at 6:50 where channel 2 is missing. There are 8VSB RF modulators like those used in cable TV which do not interfere with the adjucent channel.
You mean ATSC modulators? No doubt they work well with today’s digital TV signals, but they are pricey.
@oasterHobby
Even on analog NTSC, there are 8VSB modulators that do not interfere with the adjacent channel and they are used by Cable TV operators.
At 2:54 I have 4 of this F type to jack adapter. I have an outdoor FM antenna and with this adaptor I connect my smartphone to the antenna, all channels come in excellent. You also need an two jack female input to one jack male ouput Y adapter, One input is from the antenna and the other is for the headphones, and the male jack connects to your smartphone.
Nice, they seem like really handy accessories to have.
@@NorthcoasterHobby It's worth for every phone that has FM radio feature. For smartphone there are apps but what happens if the internet connection is unreliable but your favorite radio station is also broadcasting on FM? The F type to jack connecter and the Y adapter and an outdoor antenna are excellent. The headphones don't make a good antenna only for strong FM stations or if your using your phone outside.
@@Nicholas_Chris some phones lock that FM feature out, probably so people have to buy music.
Wowww you explain very well but if I want my channel goes everywhere what can I use for that
You would need multiple
I have the radio shack RF modulator like yours and a small portable tv, what else do I need to pickup over the air content? I unfortunately don’t have any antenna inputs like yours.
You would need a TV antenna (indoor or outdoor- outdoor is better) and a TV with an ATSC tuner (digital) or a digital converter box to connect to an older television. Here is an example of a digital converter box currently available:

Thank you.
@@mikemakin6672 You’re welcome.
Hey, quick question. What material are your radio shack modulators made of? I've been doing some research into finding a decently performant RF modulator, and I've been recommended to pick up an older radio shack one but I was told the metal ones work better than the plastic ones they produced later on. I found a couple of the ones you have on ebay but I'm not sure if those are the plastic ones or the metal ones that are being spoken of. Thanks in advance!
The RF modulator in the video is in a metal case.
Perfect, thank you so much! @@NorthcoasterHobby
@@jessesinclair161 You’re welcome.
I've become numb skulled due to progress. I have everything here and then some but let myself forget how to hook everything up. I love my smart tvs but due to becoming disabled earlier than anticipated, and now on an extremely low fixed income compared to my work income, I had to cut cable tv out. I'm so glad I suffer from the love of nostalgia and saved everything in impeccable condition. Who knew we'd be having such difficult times as we're seeing today? The Walking Dead knew!
I wonder if you can use an antenna that is connected into an rf port and send the signal to a new tv.
I’m trying to build an N64 that connects to the tv through antenna by using the mult port RF adapter and a booster for the antenna so I can make a wireless N64. Problem is I like crts but the loud ringing is just horrible.
The converter box has its own rd output on it. No need for the extra modulator.
Unless your TV tuned down to 55 Mhz
I know this is a 10 month old video but I’m hoping you can answer my question, I have a 80s Korean made portable TV. With only a headphone jack port on top, will that work with the coax cable 3.5mm head and RF modulator?
If the headphone jack is the antenna input, then yes.

@@NorthcoasterHobby thank you! after seeing yours I understand what kind of adapter I’d need. My external antenna point is the old style with the two screws, similar to old speakers for receivers and turn tables. Google is an amazing thing one search and I found the adapter from the two little metal forks to a coax cable head.
Hiya..can you tell me what volts and amps the adapter is for you little memorex? mine isn't displaying full screen, I'm think maybe my adapter is too weak
Hi, sorry for the late reply. The adapter is 12V DC 1.0 Amps.
@@NorthcoasterHobby ah thanks that's exactly what I thought
@@Limousine08 You’re welcome.👍
Hi! I need a device that converts the signal from RF to CVBS (RCA). Do you know such a device?
I’ve never seen a device like that.
Would this work if my rf adapter is broken off on my TV?
No, it would need to be fixed.
These are really easy to find at thrift store..
I found a general electric one at a thrift store lol
They are...
Found a couple RCA brand today at a thrift store, for $3 each.
Every time I got to good will I see them
I think it’s because when people had old tvs back in the 80 90s most people had these
At 2:55 what is that small tv coax adapter called?
F-type female to 1/8” or 3.5 mm male plug.
@@NorthcoasterHobby thanks
@@eagonsiahaan9390 You’re welcome.
I giving maduletars
That also used for portable or pocket TVs
Wish there was a way to connect it to my 80s portable tv that has no inputs only an antenna
Clip the coaxial cable to the antenna from your source, as in this video:
ruclips.net/video/nGuH18paMog/видео.htmlsi=IQy23ZrjaDVhI4p3
What do you recommend for streaming hdtv via coaxial cable to multiple tv's in a hotel?
If you are using an antenna as your source, then a series of distribution amplifiers could distribute the channels to multiple televisions.
@@NorthcoasterHobby I will use some hdmi player, android or raspberry pi as a player. If there is an existing coaxial cable with working tv and nice signal, would i need an extra signal booster to stream my program through the same cable?
@@ivanlitovskii Possibly. It depends on what channel you modulate it to- if there are any strong signals on adjacent frequencies then a booster may be needed.
can these modulators use for fm tuners if i set them on fm band frequency like 90Mhz, 92Mhz..?Im planning combine them together with summator and amplify to one coax cable, like cable TV, but for radio stations from web-radio
@@leesallow7701 These only modulate to RF channels 3 or 4. Sounds like you’d need something more specialized.
when the s-video doesn't state if in or out,what is it,both?
Most likely it is an input.
Got my first TV with no analogue tunner.
I use this for my ps2 😂😂
@2:00 you mention receiver connected to rf modulator but unsure if you referring to like converter box receiver?Will hdmi signal be enabled?
Yes, I was referring to a converter box receiver or satellite receiver. There is no HDMI signal as the modulator is analog.
@@NorthcoasterHobby ok so that is why the rf modulator alone will not provide tv video ok.
@@NorthcoasterHobby how can you tell why a sdtv converter box mostly will not work?I got a couple from thrift stores.
@@robertshade8631 The modulator converts a video signal (RCA) to RF channel 3/4.
@@robertshade8631 How can you tell if it won’t work?
I buy these whenever I find them. Some are fancier than others with connections for other things too. So what am I ever gonna do with 20 or so RF modulators? I dunno. I just like old technology. Besides most were under $6. I figure I can pretty much get my money back if I ever needed it. But what the heck! They would be $120-ish? Definitely not a college fund for grandkids.
A little confused, why would I connect the rf transmitter directly to the tv if the point of it is to transmit to the tv?
It is a wired connection, not wireless. It’s a modulator, not a transmitter. A modulator converts a line-level signal to an RF signal. The connection is made via coaxial cable between the modulator and the TV.
25 years ago not all TVs had a video input, if there's only an RF port then you'd need a modulator to convert AV onto a TV signal
You can use these as a transmitter, but you'd need a booster to amplify the output
Connect a TV Antenna to the Modulator,
He doesn't need to because he used the signal combiner.
ive been thinking about getting one or two of these and getting raspberry pis to play movies of my plex server and make a dummy movie channels as well hook up my CCTV to it.
Great ideas! I’ll keep them in mind, thanks for watching!
Yes all modulators work on channel 3 or 4 - try a UHF modulator

A modulator like this would be useful for that.
