Best Converter to Convert Coax Cable to HDMI

Want to convert coax cable to HDMI? If you want to purchase a new TV, then chances are it won’t have a persuasive or coax connector at the back. It may have lots of HDMI, component connectors and USB but no coax. While having a satellite box or older cable that only outputs coax, you have an issue related to connecting the two. That’s why to a Techilife reader last week which prompted this guide on how to convert coax to HDMI.

The reader bought a brand new 50” UHD TV. The reader thinks that they have gotten the deal of the century and everything they wished. Until they bring it home and found only HDMI and component connections on the back. So having an older satellite receiver they don’t know how do they join the two? Let’s come and take a look:


While it may look obvious to some of you, not to consider the output of the receiver is quite easy. A few years ago, coax was the default output and has only recently been fully replaced by HDMI or SCART. Many satellite and cable receivers came with coax, SCART and HDMI. Some were purely coaxed.


Certainly, Coaxial cable was designed to carry radio signals. It is constituted of a copper core of two layers surrounded by shielding and insulation. The major thought was to deliver analog signals with a minimum of interference. Until recently, the technology was in use first on radio, telegraphy then TV and then broadband. It was slowly replaced with fiber or other technologies that offered quick transmission speeds.

However, coax is wrapped, the signal needs recurrent repeating and results in data loss over distance. Nowadays coax was popular due to it’s superiority to anything else at the time, was cheap, simple and easy to use. It was also very tough. Fiber is very 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)

HDMI stands for High-Definition Multimedia Interface. It is the modern replacement for coax in the home and used to carry signals between devices with a huge amount of data possible for high definition. Not only this but also it can carry audio too. Japanese TV manufacturers invented HDMI to help improve image quality and work unusually well.

HDMI is purely digital. So, therefore, it is fully covered against loss and does not need periodic repeating over distance. It can carry the same size of data at higher speeds. Digital transmissions are resistant to interference when the correct configuration is used so it is very powerful and essential within busy households with lots of devices and Internet networks.


As the case described above, our reader buys a new TV with no coax input and a satellite receiver with only a coax output. So how they connect the two? There are different ways. Simply they ask their satellite provider to update their receive or else they buy a coax to HDMI converter.


Well, if depending on the supplier and satellite receiver contains only a coax output, it is because of replacement. Except for SCART or any HDMI output means it could be anything up to 25 years old and must 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.


They usually come as an adapter. Those having larger AV setups may need a more involved convertor unit but remaining, a simple and easy coax to HDMI converter box will suffice. However, other retailers offer products that are quite similar too.

How does the converter work?

It takes the analog signal and changes it into a digital signal for HDMI. Either it comes with cables connected or has sockets for each cable at either end. However, some converters perform a straight conversion, just a signal for a signal. Remaining include scaling that snap a standard definition coax signal and change it into a high definition digital signal. Which one do you go for it?

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

Converting coax to HDMI is not that tough but needs a little extra investment. If you’re facing the same situation there is a fix around it and it won’t cost as much as you might think.
