So of course it would only be an engineer that would get excited about a subject like this, but have you ever wanted to know a little about the wonderful transmission media of coaxial cables?

It is an exciting world of intrigue, design, love triangles, deception, murder and mystery. Well, not all of that is really accurate—(except for the design part).
Imagine a technologically advancing world. The second industrial revolution was in full bloom, and the first electric streetlight was just installed in Wabash, Indiana, making it the first electrically lit city in the entire world. Railroads were being mass produced and pushing emerging technology out to the rest of the world. In 1880, the self-taught electrical engineer and mathematician Oliver Heaviside, (yes, for all of you extreme geeks like me, he is the man responsible for the Heaviside functions of differential equations in calculus), had just patented the first design for the coaxial cable.

Since the beginning, the biggest problem with transmission of any type of coaxial cable was the interference that is introduced into the transmission by external noise and interference. Ollie had noticed that by putting his transmission inside of a “shield”, he was able to get a lot cleaner transmission. And thus, the coaxial cable was born.
The idea behind the coaxial cable, is that by surrounding your transmission medium by a metallic shield that is tied to the ground, you can bleed off most of the atmospheric interference that a usual transmission cable can pick up on its journey from transmission to reception.
This is more or less like using a payphone on a busy street or in a rock concert, (If you still remember what payphones are :-). If you are out in the middle of everyone it will be difficult to hear what the person on the other line is saying. But if you were to stand in a sound-proof payphone booth, then you would be able to carry on a very reliable conversation without going hoarse and screaming “What? I can't hear you! Can you speak up?” It’s remarkable that the idea for a coaxial cable was developed 130 years ago and we are still using the same design today.
Today, there are over 28 common types of coaxial cable. The most common of which, (thanks to the television and cable TV industry), is the RG-6 cable, which is slowly becoming a second seat to the RG-6Q coaxial cable, (it adds a nifty second shield and foil to the shield). The RG-6Q is even cooler than its predecessor because it allows you to get even faster data over a coaxial cable. It's like a phone booth inside of a phone booth.
So next time you see a coaxial cable, I’d recommend showing a little appreciation for it. It was a genius that created it, and in technology years, it has lasted even longer than the computer, calculator, or even Reebok Pump shoes.
