On the other hand, a TV can have multiple HDMI, USB, and component connectors, but does not have a coaxial connector. If you have an older cable or satellite set-top box that only outputs a coaxial signal, you may have trouble connecting the two devices.

You might think that coaxial cable is long obsolete, but there are plenty of different devices that require this cable and which we still use today. If you’re still using an old VHS player or an old game console, or maybe you’re using an antenna, you have many options.

Step-by-Step Guide on How to Convert Coaxial Cable to HDMI

So, in this article, we are going to tell you how to convert the coaxial cable to HDMI. A coaxial cable is an electrical cable consisting of a central wire and a metallic braid separated by a dielectric layer (internal insulation) and encased in a common external shell. Coaxial cable was until recently the most widely used, which is due to its high noise immunity (due to the metal braid), as well as higher than in the case of twisted pair, allowable data transmission speeds (up to 500 Mbit/s), and large allowable transmission distances (up to a kilometer and above).

It is more difficult to physically connect to it for unauthorized sniffing of the network, it also gives noticeably less electromagnetic emissions to the outside. This technology was used until recently, first in radio and telegraphy, then in television, and then in broadband communications. This technology was eventually replaced by fiber optics or other technologies that provide higher data transfer rates. Although coaxial cable is insulated, the signal requires frequent repeating and is prone to data loss over distance.

Step 1 – Get the Right Hardware

Coaxial cable was popular because at the time it was superior, cheap, and easy to use. Fiber optic is faster and can transmit more data at the same time. Although fiber optic requires a larger initial investment, it needs less maintenance. HDMI, or High-Definition Multimedia Interface, is a modern alternative to coaxial cable.

It is used to transmit signals between devices with as much data as possible for high or ultra-high definition broadcasts. It can also transmit sound. HDMI is purely digital, so it is isolated from loss and does not need frequent repetition over distance. It can transmit more data over a distance of the same size at higher speeds.

Digital transmissions are not susceptible to interference if the correct configuration is used, so it is very useful in large families with many different devices that connect to WiFi and do not conflict.


If you have indoor or outdoor antennas with coaxial cable and no coaxial input on your TV, you will need a simple OTA adapter from coaxial cable to HDMI, which costs $30 to $50.

  1. The low price is due to the fact that no major conversion components are required because over-the-air signals are not encrypted like cable TV.

If you want to convert the coaxial cable to HDMI, you have to follow these steps:. First of all, connect your coaxial cable from your source to the “Coax In” connector on the adapter;. After that, plug an HDMI cable into the “HDMI Out” on your adapter:.

  1. Connect the other end of the HDMI cable to the TV;.

Then, make sure that both of your devices are turned on;. Set the adapter to channel 3 or 4 to receive a coaxial signal;. Finally, set your TV to the appropriate HDMI input. So you’ve just had cable installed and want to take advantage of your fancy new TV. Here’s the thing: most TV’s don’t actually have a coaxial input port.

Instead, you’ll have to use a signal converter box as a kind of go-between. This sounds complicated, but it’s really not. We’ll walk you through the process step-by-step to clear things up and let you get back to watching your favorite shows.

  1. If your cable provider has given you a cable box, you’re good to go.

If not, or if you’d like to connect the coaxial cable directly, you’ll need a signal converter (sometimes called a signal adaptor) box. You can pick one of these up online for around $20, and they’ll also let you convert SCART to HDMI, so you can use old peripherals like VCR players.

Reasons to Convert Coax Cable to HDMI

Now, while you might be able to find a signal adaptor in an electronics store, it’s sort of a specialist item in our digital age. As such, you probably won’t be able to pick one up from Walmart, so it pays to purchase this in advance of your services being connected.

Considering buying an android TV box?

We have a list of the best android TV boxes right here, check this out! On the back of your cable box/signal converter, you’ll see what looks like a screw sticking out. This is actually what you connect the coaxial cable to. Carefully attach the coaxial cable here, and tighten the nut until it’s nice and snug. You should be turning the nut clockwise.

It’s very important that you don’t use tools here or you run the risk of damaging the connector.

This part is really simple. There should be an HDMI port labeled “Input” on the back of your TV. Put one end of the HDMI cable into this, and the other end into the HDMI port on your cable box. Since HDMI cables only go in one way, there shouldn’t be any confusion here.

Plug your TV and whatever other device you’re using into the outlet.

Flip the switch to turn them both on. If your TV screen stays blank, go into the menu. You’re looking for an option called “Input” or “Source”. Most of these options should be greyed out and inaccessible.

If you’ve done everything right, there should be one that’s highlighted, so select it to change to that input.

Remember: sometimes cable boxes can take a few minutes to properly start, until which, you might not see anything on the screen. Even though you can’t directly connect a coaxial cable to most modern tech, there’s always a workaround.

Step 4 – Power On

By using a signal converter as a middleman, we can quickly and easily resolve the problem and take advantage of our services.

  1. How to convert coaxial cable to HDMI

So what can you do? You could simply convert the coaxial cable to HDMI to keep enjoying your shows in better picture quality.

  • Reasons to Convert Coax Cable to HDMI.
  • Step-by-Step Guide on How to Convert Coaxial Cable to HDMI.
  • When it comes to the battle between coaxial cables and HDMIs vis-a-vis video and audio quality, HDMIs win almost every time.
  • Indeed, an HDMI cable will almost always deliver better picture and sound quality than coaxial, depending on the design of the receiving equipment and how it’s set up to handle data.

Where a coax cable may be vulnerable to radio frequency and noise interference (depending on its shielding), HDMI cables come with detailed digital audio and video transmission capabilities that cover separate connectors and wires to transmit digital data. This means that while the bus topology of coax cables makes the deployment of this data prone to congestion, noise, and some security risks, HDMI cables have no such issues.

Apart from the reasons already laid out here, there are several other advantages that HDMI has over coax cable, which are difficult to ignore:. HDMI cables can offer you 1080p with the Ultra-High-Speed variety going up to 10K resolution, while your run-of-the-mill coax cable offers you 1080i or 720p.

Step 2: Connect the Signal Converter to Your Coaxial Cable

  • This means that when you use a coaxial cable instead of an HDMI cable, you’ll never be able to get the full HD signals that you might want.
  • Coaxial cables are easier to use because they’re much smaller than HDMI cables. HDMI cables make up for this deficit by combining both audio and video signals.
  • This means that you’ll only need one HDMI cable as opposed to multiple coaxial cables.
  • You can use a single HDMI cable in place of about 11 coax cables; this is because you can use that HDMI cable to connect TV boxes, TVs, DVD players, and a host of other audio/visual receivers in your home.

Step 2 – Connect Your Coaxial Cable

  1. Step 3 – Connect your HDMI Cable

HDMI cables handle 10-bit, 12-bit, and even 16-bit color depths, which coaxial cables can’t do, allowing HDMI cables to deliver superior picture and color quality. With these reasons in mind, you can see why it might be a good idea to convert coaxial cables to HDMI.

The very first thing you should know is that you’ll need something called a signal converter box for this to work. This box acts as a converter for your cables. That being said, here are the step-by-step instructions on how to successfully convert your coax cable to HDMI:.

Signal Quality

In some cases, your cable provider will give you a cable box.

If that cable box has these conversion protocols built-in, then you are good to go. However, if this isn’t the case, then you will need to get a signal converter, also known as a signal adaptor. It converts component signals (component video and optical audio) to HDMI format.

You can easily find one of these online at a relatively affordable price.

At the back of your signal converter, you’ll see a port labeled “Coaxial.” This is where you insert your coaxial cable.

Be sure to gently screw in the cable connector to make sure that the cable doesn’t come loose with time or movement, thus distorting the connection.

NOTE: Don’t be tempted to use tools to tighten this nut. Just use your fingers; otherwise, you run the very real risk of damaging the coaxial connector. There should be an HDMI port at the back of your TV. Newer TVs have several HDMI ports that you can use. This step is very simple: all you have to do is connect one end of your HDMI cable to the back of your TV (the HDMI port), and the other into the HDMI output port of your signal converter.

The beauty of HDMI cables is that they only go in one way, so this step shouldn’t give you as much of a headache as with audio/video cables.

Once you’re sure you’ve correctly connected everything, it’s time to turn on the TV, as well as all other connected devices in use. Your TV screen will go blank. If this happens, get your remote control and go to the TV menu. On the option labeled, “Source” or, in some cases, “Input,” select the HDMI port that you had designated for this exercise.

It could be HDMI 1, 2, 3, …and so on.

The best part is that your TV will tell you if you have done everything right. Typically, most, if not all, of these options will be greyed out except the one that is functional.

That one will be highlighted, and it will be the one with the live connection (input signal).

  • Take note that in some cases, your cable box might take a few seconds or minutes to fully come on and start operating.
  • In this instance, you’ll still have a blank screen even after selecting the right HDMI option.
  • Just give it a little while to warm up and get going.
  • This is how you convert coaxial cable to HDMI.

It’s a simple process that might call for buying the right signal converter and just connecting the right cables to the correct ports.
