What is Coaxial Cable?

Picking out and finding electronic components can be a hassle if you don’t know electronics. Abbreviations, nicknames, and subtle differences don’t translate to the everyday consumer which can leave plenty of people scratching their heads or seeking help in the electronics aisle. One of the most popular consumer electronics components is the simple coaxial cable.

So, What is Coaxial Cable?

Coaxial cable, often abbreviated as coax cable, can be found in most American households with cable television. Coaxial cable is a type of signal transmission cord that utilizes a copper core to send signals from different devices. The copper core is surrounded by an inner insulator, which is wrapped in a woven copper shield, which is all bundled up into an outer plastic sheath for insulation and to keep out outside elements.

Coaxial cable was actually patented in 1880 by engineer Oliver Heaviside who sought to create a more efficient shielded cable. The coaxial cable proved itself to be more efficient in signal communication while also being less prone to electromagnetic interference and less likely to be interfered with by other metal objects such as gutters on a household.

How Do I Use Coaxial Cable?

Luckily, coaxial cable is a simple cord. The cord itself uses a male-female connection to connect different components. Let’s use a cable television connection as an example. Find the female cable outlet on your wall. Insert the male end of the coaxial cable into the female outlet then use a clockwise motion to screw the male end until you have a snug fit. Plug the other male end into the female receiver such as the cable receiver box and again tighten until you have a snug fit. Now you know the basics of using coaxial cable.

While there are industrial cable products such as HDMI and DVI that may provide higher quality signals, the coaxial cable is still the standard bearer when it comes to many types of home electronic connections.
