Best HDMI RF Modulators To Buy In 2024

The golden days of coaxial and audio/video cables have long passed. However, there is still a charm and nostalgia for older TVs. If you have one lying around, you might be wondering how you can still get some use out of it. An HDMI RF modulator can help make that happen.

A modulator solves the problem of connecting modern media devices to older TVs and monitors, preventing them from becoming obsolete.

However, there is not much information when it comes to these products. Picking between them is not easy for the average consumer. To save you time, we’ve compiled some of the best HDMI RF modulators so you can buy the right one for your needs.

What Is an HDMI RF Modulator?

An HDMI RF Modulator takes HDMI input from devices with HDMI output. This includes media players, set-top boxes, or consoles. It converts the signal from these devices into Radio Frequency also known as RF. This is then transmitted through a wire, usually a coaxial or A/V cable. These RF signals can also be received by TVs with antennas if you are looking to go towards a wireless route.


RF modulators come in various shapes and sizes with different input features. However, since we are mainly talking about HDMI RF Modulator the input is usually HDMI. So, each modulator on this list features an HDMI port that can take input from modern devices such as consoles, gaming PCs, laptops, and even Blu-Ray Players.


HDMI RF Modulators work by converting HDMI signals to RF, short for radio frequency. However, directly converting them can cause a loss of video and audio stutters or quality. This is usually due to interference. Hence, the HDMI signals are passed through or mixed with higher frequency waves to prevent. That’s where the “modulation” comes into play, hence the name.

To sum it up, it takes the signal as an HDMI input, converts it into an RF signal, and cleans up the loss of quality. The image/video then shows up on your TV without any real loss of image quality. Of course, this also depends highly on what sort of TV you pair the modulator with.


After cleaning up the quality a bit through the modulation process, the HDMI RF Modulator will output the image/video to your TV of choice. Usually, an HDMI RF modulator will feature only a single RF output. You will need a coaxial cable to connect the device to your TV. In some cases, you’ll even find an HDMI output on these modulators. That will come in handy in case you want to connect different TVs or displays from a single source.

However, it’s not going to be for everyone. This is especially true since you have to take the difficult setup process into account.

With that said, if you are in a situation where you need a high-end professional-grade HDMI RF modulator, then this is the one to buy.

More Niche Stuff: Best Indoor Helicopters

Do I Need an HDMI RF Modulator?

By now, hopefully, you are aware of how an HDMI RF Modulator works. Most of the time, it is a cheap and easy way of taking advantage of that old TV that you have lying around. If you want to get some use out of it, picking up an HDMI modulator is a good choice. Considering the recent rise of retro gaming and hardware in the past few years, it’s an easy way to get the old-school experience without wasting a lot of money.

More Retro Tech: Best Retro Handhelds 

There’s another niche use case for these modulators. They can be used to separate audio and video signals from such as cameras, portable VCRs, satellite receivers, or even from computers. It then turns these signals into VHF TV signals. This works well for TVs that don’t have a composite video output.

Many HDMI RF modulators are also popular for distributing a single signal from something like a TV player to hundreds of TVs. However, those products are more catered towards professionals, and won’t be found as easily with retailers. 

In most cases, if you have a TV that only takes a coaxial cable as an input, then you’ll need an HDMI RF modulator if you want to use it with modern devices. At the end of the day, it’s cheaper than buying a brand-new TV after all.

How We Picked and Tested

Usually, when we’re putting together a “best of” article on Appuals, we put every product through a rigorous and tedious testing process. Selecting the best of the best HDMI RF Modulators among the myriad of options available online was no easy task. This is especially considering the fact that most of them are professional-grade options, and feature information that is confusing to the average consumer.

As such, we decided to compile our list based on ease of use, the setup process, and overall result in terms of image quality. Everything else was just marketing fluff. Keeping these three things in mind, we were able to compile six of the best HDMI RF Modulators out there.  

Of course, some are more expensive than others. This doesn’t necessarily mean that expensive RF modulators aren’t worth it, it’s just that a good number of them might not be worth it for you. Most people reading this already have a niche use case, and further confusing them with utterly expensive options would not make much sense.

Despite that, we still included a few high-end options for the odd reader that is looking out for some professional gear. After we cherry-picked six of these modulators, we decided to test them based on different metrics.

The most important to us was image quality. It’s fine if a modulator can just provide a simple output, but if the image quality is bad, then the experience is not worth it. As such, we made sure that every modulator on our list would not get any complaints from the average reader.

The modulators were then ranked based on ease of use, setup process, and again, the quality of the image output. After extensive research and thinking, the above list is what we ended up going with.

Buyer’s Guide

The modulator market is confusing, and it is filled with technicalities. For a new buyer, it can be overwhelming and hard to find a good option, And the saturation of the market does not help as well.

To make your life a little easier and help you find what you are looking for, our team tested dozens of modulators and sifted through tons of options to ensure you get the right product.

And after investigating, we have compiled a list of factors that you need to consider before buying an HDMI Modulator

Video Quality

Video quality is a big factor when it comes to buying an HDMI RF modulator. So, it is a good practice to always check video output in the specification area.
When it comes to quality everyone has preferences. Now, most modulators have 1080p video output which is usually adequate for most people. But if you are looking for the top-notch 4k experience, it can cost premium


RF modulators come in different varieties with different input and output supports.
And speaking from experience it is a real hassle if you buy something and end up finding out it does not support your device. So, it helps to research a bit about your TV’s connectivity and the ports and input options it has. Most options we included in our list have HDMI to AV and Coax support so you can check them out too.

Value for Money

Like everything, the prices of HDMI RF modulators vary a lot. There are options under 100$ while other costs more than 500$. Surprisingly the prices do not relate to the quality of the modulator at all.

It usually depends on what your problem, in particular, is but it is still wise to read the feature list and see if it has value for money and if the features match the price. It is a good practice to compare the features with the cheaper ones and see the value you are getting for that extra money.

Best HDMI RF Modulators - FAQs

Are RF Modulators still used?

Usually, you’ll find that RF modulators are still used in conditions where a display requires an audio/video signal through a coaxial cable. Most modern devices these days don’t have an RF port, so an HDMI modulator is crucial. They are also widely used in stadiums, hotels, malls, airports, etc.

Can RF be converted to HDMI?

RF signals can be converted to HDMI signals by using an RF to HDMI adapter/converter. These devices do the opposite job of an RF modulator. They take input input from coaxial cables, and the output is carried to your device by an HDMI cable. Projectors are a common use case.

How do you hook up an RF Modulator to an older TV?

You can easily hook up an RF modulator to an older TV by using the right cables. Connect a coaxial cable from the TV jack to the RF modulator. Then, connect an HDMI cable from the modulator to your source (DVD player, Console, PC, etc). You should now have a working signal.

What does an HDMI modulator do?

An HDMI modulator transforms input from an HDMI signal and outputs it in the form of an RF (antenna) signal. This allows you to view the image/video from the source device in full resolution, even on older TVs.
