How to Convert Coaxial Cable to HDMI (2021) - TechCult

Coax cables were considered the sole standard for connecting your TV and cable box. It was the default output for many years. Nowadays, it may sound outdated, but they are still used extensively. Usually, Coax connections are used to receive a connection in our homes from a satellite. If you have an old cable satellite box at your home, you must know that it only outputs Coax. Now the problem arises when you buy a new TV. As technology has advanced, new TVs do not support Coax and supports only HDMI and USB. So here we are with the solution to convert Coaxial to HDMI cable. 

How to Convert Coaxial Cable to HDMI

There are plenty of Coaxial to HDMI cable connectors available in the market. You can get them online or offline. In this article, we will tell you how to convert Coaxial cable to HDMI. But first, let us see what an HDMI and a Coax cable is and the difference between them.

Coaxial Cable

Invented in the 19th century, Coaxial cable was used to carry out radio signals. It has a three-layer architecture. Coax cables are made up of a copper core and two-layer insulation above that. It was meant to transfer analog signals with a minimum of hindrance or interception. Coax cables were extensively used in radios, telegraphs, and televisions. It has now been replaced by fiber and other technologies that promise faster transmission.

Coax cables are prone to data/signal loss over distance. Fiber technology is faster and more reliable than Coax but requires more investment. Coaxial cables require minimum investment and maintenance.

HDMI Cable

HDMI stands for High Definition Multimedia Interface. It was invented in Japan by the Japanese TV manufacturers and is the most popular replacement for the coax cable at homes. It carries out signals among devices with a colossal amount of data and broadcasts signals at high definition or ultra-high definition interface. It carries audio too.

HDMI is a digital cable. It is void of any data losses. It carries more data than coaxial cable and can deliver signals at a much faster speed. It performs digital transmission and is hence void of any interference or hindrance. Nowadays, every TV, broadband, and other cable device comprises HDMI ports instead of coaxial ports.
