How to Convert Coaxial Cable to HDMI

How to Convert Coaxial Cable to HDMI

If you bought a new TV, it will likely not have a coaxial connector. It may have multiple HDMI, USB, and component connectors but no coax. If you have an older cable box or satellite box that only outputs coax, you may have trouble connecting the two.

You might think that coax is a bit outdated, but there are lots of amazing tools we still use today. Whether you are still using an old VHS player or an old game console or maybe you are using an antenna, there are many options available to you. In this article, we will walk you through the options for making your old technology compatible with your new device.

AV connection type

While this may seem like a mistake to some of you, not completely considering the receiver output is an easy oversight. Over the years, coax is the default output and has recently been completely replaced by SCART or HDMI. Many cable and satellite receivers come with coax, SCART, and HDMI. Some are downright persuasive.

Coaxial connection

Coaxial cable was invented around the 19th century to carry radio signals. It consists of a copper core of two layers surrounded by insulation and protection. The idea is to transmit an analog signal with minimal interference. These technologies are used today, first in radio and telegraphy, then TV and then broadband. It is gradually being replaced by fiber or other technology that offers faster transmission speeds.

Even if the coax is isolated, the signal needs to be repeated frequently and data loss may occur due to distance. Coax was popular because it was superior to anything else at the time, cheap and easy to use. It is also very durable. Fiber is faster and can carry more data at once. Although fiber requires more investment up front, it requires less maintenance.

HDMI

HDMI, or High-Definition Multimedia Interface is a modern replacement for home coax. It is used to carry the signal between devices with the maximum amount of data possible for high definition or ultra-high definition broadcasts. It can carry audio too. HDMI was created by Japanese TV manufacturers to help improve picture quality and performs very well.

HDMI is purely digital and therefore isolated from repeated and unnecessary losses over long distances. It can carry more data farther for the same size at a higher speed. Digital transmissions are immune to interference when the correct configuration is used which is especially useful in busy households with many WiFi devices and networks.

Change coax to HDMI

There are several ways to convert your Coax to HDMI and vice versa. Depending on the device you are trying to connect to, one option may work better than another. Either way, it will take some upgraded tools to connect everything and work properly.

Depending on your cable provider, if the receiver only has a coax output, it will need to be replaced. Not including SCART or HDMI output means it could be anything that is up to 25 years old and must be replaced. However, if it works fine or your service provider wants to charge you for an upgrade, it may not be your best option.

Coax to HDMI Converter

The Coax to HDMI converter usually comes as an adapter. Those with larger AV setups may want a more involved converter unit, but for all of us a simple box to HDMI converter will suffice. This page on Amazon has a lot of them for sale. Other retailers will also offer the same type of product.

The converter takes the analog signal from the coax and converts it to a digital signal for HDMI. It will either come with the cable attached or have a socket for each wire at both ends. Some converters perform direct, signal to signal conversion. Others can include scaling that takes a standard definition coax signal and converts it to a high definition digital signal. Which one you choose depends on your needs.

Connecting the TV to a satellite receiver in this situation is very easy. You take the coaxial output from the satellite receiver and connect it to the coax input on the converter. You take the HDMI feed from the converter and plug it into the HDMI input on your TV. Now you can set the satellite receiver as your source and watch TV.

Converting coax to HDMI isn’t difficult, but requires a little extra investment. If you are in the same situation as our readers, there is another way and it doesn’t cost as much as you think!

Frequently Asked Questions

Here’s some more information on coax and HDMI:

Which is better, coax or HDMI?

In addition to the nostalgia that users get from seeing a brightly colored coaxial connector, everyday users will benefit from making the transition from coax to HDMI. The latter provides a stronger connection and makes better video and audio quality faster. HDMI cables also only require one connection compared to two or more with coax, making them easier to use and more visually appealing.

Are coaxial cables still in use today?

Yes, some TV antenna equipment still uses cables today. For those who have cut the cable but still want their local channels, coax cable is still a part of everyday life and therefore, you need a converter to enjoy network content on your TV.
