1. RadioShack 15-2526 – Editor’s Choice

RadioShack 15-2526

Design: 62% | Durable: 74% | Price: 78% | Ease Of Use: 87% | Value: 75%| Overall Rating: 75%

At least 50 feet of coax wire are required to transmit the RF signal from this Radio Shack equipment to my television set in another room. The quality of the signal is excellent, and I haven’t seen any degradation (as far as NTSC signals go). Because of the pleasure, it has offered me, I’m glad I invested a few more dollars.

Connected a DVD player/recorder to my television. The picture is clear as a bell.

The previous VCR I was using to perform the same thing had distorted the image before I got this one.

An indicator light on the front of the device changes from red to green if a signal is detected.

An s-video input connection is also included on this device.

Because I acquired it secondhand, it didn’t come with any setup instructions. Fortunately, RadioShack has them accessible online.


  • Affordably priced.
  • Setup is a cinch.
  • To convert RCA to coaxial, use this converter.
  • Suitable for analog televisions.


  • RCA wires are not included.
  • No remote.


To kick off the long weekend with your family or friends, you will need an external and best HDMI RF modulator that will do the job. Radio Shack 15-2526 fills that need.

It comes with a user’s handbook that includes all the information you need to get it up and running. Turn on the modulator when you have completed the setup.

2. Channel Plus 5415 – Best Premium

Channel Plus 5415

Design: 70% | Durable: 72% | Price: 65% | Ease Of Use: 87% | Value: 75%| Overall Rating: 73%

If you’re thinking about purchasing it, it’s probably for a unique purpose. Adding a Panasonic DV deck’s video output to my home video system was my goal (3 TV monitors). I thought I could get away with using an old Video Stabilizer / Enhancer I had lying around.

Despite the good quality of the video, when I first connected, the audio was terrible. I was amazed when I got the Channel Plus 5415, tuned to UHF Channel 42.

It didn’t take long until I started to hear hissing in the audio, which I immediately ascribed to the signal being over modulated. I put to the test a pair of vintage splitters I thought would serve as attenuates in the short term. 3.5 dB and 7 dB, for example.

However, the audio quality was lowered as a result of this. As it turns out, the cable end of the Samsung tuner was capable of handling over modulation from cable input, and it was.

There was no problem once I reprogrammed the Channel Plus’ output to CATV channel 84. The audio noise was eliminated, and the visual quality was maintained.

Use a CATV channel as your output if you’re having troubles with over modulation. I couldn’t be more pleased with the outcome!


  • A push-button digital programming feature.
  • Built-in 25dB amplifier.
  • Uses an infrared remote control.
  • Affordably priced.
  • Conveniently sized.


  • Not programmable by a computer.


For those who do not want to use computers, it has a simple push-button digital programming feature. There are 65-15 MHz CATV channels as well as 14-64 MHz UHF channels.

3. The Cimple Co RF– Best Budget

The Cimple Co RF

Design: 69% | Durable: 72% | Price: 65% | Ease Of Use: 87% | Value: 75%| Overall Rating: 73%

I was astonished by how nicely this worked for me. As soon as I connected this to my 1978 TV and my new Spectrum cable box, I was able to watch cable TV on my vintage set.

Previously, my Spectrum cable box would not operate with my 1978 television since the 2019 cable box did not have coax out and my 1978 television only had an antenna-in connector. For six months, I talked to four Spectrum personnel who assured me that my old television was toast.

After that, I watched Carolyn K on YouTube show how to use a modulator with an analog TV. This $15 modulator has restored the 1978 television to its former glory.

A digital-to-analog converter and an antenna were options I examined, but the cost was prohibitive, and I’m not sure how much longer a 42-year-old TV will work anyhow. In addition, this cable box is now part of a package offer.


  • Compact and slender.
  • Affordable.
  • HDMI to AV converter.
  • Exceptional for playing games on.


  • Does not support high definition, three-dimensional, or ultra high definition video.


For DVD players and games, however, it is a great choice. This best HDMI RF modulator, unlike other RF modulators, may be chained together and utilized with an HDMI to AV converter to provide a coaxial signal.

4. Vecoax Minimod-Best Value

Vecoax Minimod

Design: 62% | Durable: 74% | Price: 78% | Ease Of Use: 87% | Value: 75%| Overall Rating: 75%

RF modulators like the MINIMOD-2 do not come up very often, which makes it an excellent investment.

My house is equipped with a master antenna system. Signals may be amplified using professional amplifiers that I have at my disposal. My local TVs get the best reception possible from my antenna ports. I bought the Minimod-2 so that I could connect my DirecTV satellite receiver’s HDMI output to more TVs in the home.

TVs in locations like our study or workout room, where the TV is smaller, and where the TV is seldom used, are secondary televisions. In light of AT&T’s ever-increasing DirecTV bills, the Minimum-2 appeared like an ideal solution to this dilemma.

Cutting down on DirecTV receivers allowed us to save some money each month. All of our rooms have IR repeaters, which enable us to operate remote equipment like a DirecTV receiver via our whole-house audio system.

Everything worked flawlessly from the ground up.


  • Incredibly high-definition images.
  • Setup is a cinch.
  • Connect to any HDMI source.


  • Much more costly than you would expect.


At 60 frames per second, the device can receive HD video streams of up to 1080p quality. Aside from that, it is a breeze to set up and work with any standard-def digital TV.

5. KKmoon Compact RF Modulator – Best Ease Of Use

KKmoon Compact RF Modulator

Design: 69% | Durable: 72% | Price: 65% | Ease Of Use: 90% | Value: 75%| Overall Rating: 73%

When I used the audio and video sources, the modulator created RF and TV signals, which were then sent via a channel to my analog television set.

A high-performance circuit design provided me with flawless picture reproduction throughout a wide range of VHF/UHF frequencies, ranging from 47 to 868 MHz.

Finally, it was easy to set up and use because of its humanized design. I also used a variety of CATV systems with it.


  • Compact and easy to store.
  • Affordable.
  • A circuit with high efficiency.
  • Setup is a cinch.
  • Supported by a CATV set-top box.


  • US NTSC video format is not included.


With its small size and lightweight construction, the KKmoon modulator is ideal for use at home, in schools, or in business environments.

6. E-SDS HDMI to RF Coaxial Converter – Best Compact

E-SDS HDMI to RF Coaxial Converter

Design: 62% | Durable: 74% | Price: 78% | Ease Of Use: 87% | Value: 75%| Overall Rating: 75%

The E-SDS HDMI is a well-known RF converter with a wealth of useful functions.

When you want to use it, all you have to do is plug and play.

Easy to set up and use through menu or remote, the Coaxial converter does its job well. There is a green indicator light when the converter receives an HMDI signal. It’s always on, so there’s no need to do anything special to make it operate.

Set your TV to channel 3 and NTSC for the greatest picture for the majority of Americans. The only problem is that the image quality isn’t great. On a small TV, it seems OK, but on a bigger screen, the image quality is much inferior, making it difficult to read the text.

With a little experimentation, I was able to bring the quality up a notch or two, making it just about usable. If you were relying on the closed caption text, you wouldn’t be able to utilize the converter.


  • HD video input.
  • It is lightweight and tiny.
  • Setting it up is a breeze.
  • Remote control.
  • Affordable.


  • This is not a full HD video output.


Using a projector to display a presentation from a laptop is an excellent example. The E-SDS is a typical RF modulator in that it is small, light, and simple to use. Because it comes with everything you need, you do not need to buy additional cords to set it up.

7. RCA Compact CRF907A – Best Performance

RCA Compact CRF907A

Design: 69% | Durable: 72% | Price: 65% | Ease Of Use: 90% | Value: 75%| Overall Rating: 73%

It is one of the most popular and inexpensive RF modulators on our list, and it is small enough to fit in your pocket. But why is it so well-liked?

You may also connect an A/V component like a TV that does not have any video jacks with this adapter.

A digital signal from my RV satellite receiver was transferred to my RV bedroom TV using this. In the bedroom, there is merely a coax connection that connects the main TV to the satellite receiver.

A place where the receiver could be seen from the living room was essential to my decision-making process. In order to connect the satellite receiver’s AV output to the TV line in the bedroom, this worked well.


  • A small and light package.
  • Circuit design for high efficiency.
  • It is a great bargain.


  • An audio problem.


The circuit design of this small modulator is very high performance. You can be confident that a circuit design like this will give you faultless image reproduction.

8. Dynex WS-OO7 – Best Durable

Dynex WS-OO7

Design: 62% | Durable: 74% | Price: 78% | Ease Of Use: 87% | Value: 75%| Overall Rating: 75%

Excellent service, prompt delivery at an affordable price. It’s all related in the following way: Using a coaxial wire, the converter is connected to the television. A DVD recorder without a tuner is linked to the converter via S-video and the red and white audio connections.

Audio and video lines in red, yellow, and white connect the DVD recorder to a Verizon FiOS receiver. A tuner and coaxial wires were used to replace a DVD recorder. That piece of equipment has broken down. The converter is providing me with a far better image than I was previously able to get.

My image had wavy lines at first, but it turned out to be just a sloppy coaxial wire hookup. It was a pleasure doing business with this vendor.


  • S-video input provides a sharper picture.
  • Compatible with analog TVs.
  • The setup process is quicker.
  • Extremely sturdy.


  • It is a little too expensive.


You can rely on this modulator for many years to come because of its small form and durable construction.
