How to Convert Coax to HDMI – In Detail

We usually use a Coax connection for the satellite to receive and cable connection in our homes. If you buy a new TV, chances are it won’t have a coax connector at the back. It may have several HDMI, USB and component connectors but no coax. If you have an older cable or satellite box that only outputs coax. Then you could have trouble connecting the two.

Most of the secure, analog and relatively economical transmission, They carry out this connector.

But as the technology turns, the Latest TV equipment has HDMI Connector instead of coaxial cable. To meet with this coax connection. A powerful HDMI adopter is just similar to an old RF modulator. However, we use it to convert the coax cable connection to HDMI.

There is a variety of Coax to HDMI cable connectors found online and offline stores.

Before proceedings to see the process of converting coaxial signals to HDMI. Let’s first see the difference between coax and HDMI cable connectors.

Difference between Coax and HDMI Cable Connection:

Coax cables are usually designed to carry analog signals in the form of audio-video from one place to another. Just like cable connections for our home and office TV sets. The idea to use this type of coaxial connection is to transmit radio signals with minimum interference.

While HDMI(High Definition Multimedia Interface) cables. Invented by Japanese TV manufacturers are designed to transmit digital data with high-quality audio-video to our TV sets. Relatively in a shorter distance usually within a room.

AV Connection Types:

While it may seem an obvious oversight to some of you. But not fully considering the output of the receiver is an easy oversight. For many years coax was the default output. It has only recently fully superseded by SCART or HDMI. However, many cable and satellite receivers came with coax, SCART and HDMI. Few were purely coax.

Coaxial Connections:

Certainly, Coaxial cable was invented in the 19th century to carry radio signals. It is made up of a copper core of two layers surrounded by shielding and insulation. The idea was to deliver analog signals with a minimum of interference. Until recently, the technology was in use first in radio and telegraphy, then TV and then broadband. It was gradually replaced with fiber or other technologies that offered faster transmission speeds.

Even though coax is insulated, the signal needs recurrent repeating and is subject to data loss over distance. Nowadays coax was popular because it was superior to anything else at the time, was cheap and easy to use. It was also very tough. Fiber is faster and carries a large amount of data at once. Though fiber needs more upfront investment, it needs less maintenance.


HDMI (High-Definition Multimedia Interface) is a proprietary audio/video interface. They use for transmitting uncompressed video data and compressed or uncompressed digital data. It is the modern replacement for coax in the home. They carry signals between devices with the maximum amount of data possible for high definition. From an HDMI-compliant source device. Such as a display controller to a compatible computer monitor, video projector, digital television or digital audio device. HDMI is a digital replacement for analog video standards.

High-Definition Multimedia Interface is the modern replacement for coax in the home. It carries signals between devices with the maximum amount of data possible for high definition or ultra-high-definition broadcasts. It can also carry audio. Japanese TV manufacturers invent HDMI to help improve picture quality and work exceptionally well.

It can carry more data further for the same size at higher speeds.

Convert Coax to HDMI


Convert Coax to HDMI:

our reader has a brand new TV with no coax input and a satellite receiver with only a coax output. So how are they going to connect the two? There are a couple of ways. They could ask their satellite provider to update their receive or they could purchase a coax to HDMI converter. So this is what you can do in that situation. There are different ways. They ask their satellite provider to update their receive or they could buy a coax to HDMI converter.

Satellite upgrade:

While depending on the supplier, if the satellite receiver has only a coax output, it is due for replacement. Except for SCART or any HDMI output. This means it could be anything up to 25 years old and should be replaced. However, if it is working well or your service provider wishes to charge you for an upgrade. It might not be your best choice.


Coax to HDMI converters usually come as an adapter. Those having larger AV setups may need a more involved converter unit. But for the rest of us, a simple coax to HDMI converter box will suffice. Other retailers offer the same kinds of products too.

The converter takes the analog signal and converts it into a digital signal for HDMI. Either it comes with cables attached or has sockets for each cable at either end. Some converters perform a straight conversion, the signal for a signal. Others include scaling that takes a standard definition coax signal and convert it into a high definition digital signal. Which one you select depends on your needs.

Connecting the TV to the satellite receiver is very straightforward. You can also take the coaxial output from the satellite receiver. And you can connect it to the coax input on the converter. You can take the HDMI feed from the converter and attach it to an HDMI input on your TV. Now you should be able to set the satellite receiver as a source and watch TV.

Converting coax to HDMI is not difficult but requires a little extra investment. If you’re in a similar situation. Then there is a way around it and it won’t cost as much as you might think.
