If you have ever seen a cable connected to your TV or security cameras that features the description "RG59", you may wonder what it is. You may be wondering, “What is this cable and where does it come from? This tutorial will cover everything RG59 Cable. We will cover the history behind it, how it works, pros and cons, and common use cases. Without further ado, let's get into it!
RG59 was invented way back when, during the early 1950s. The US Navy had started utilizing a particular type of cable known as coaxial cables for communications purposes. Meaning these cables were very much useful to send messages over long distances. Later on, RG59 Cable was adopted by radio and television stations as well for their signal broadcasting. RG59 Cable would during the 1970s become the standard cable used for cable TV installations throughout the United States. That means a lot of people were using it at home for watching TV.
Those letters in RG mean "Radio Guide," providing a hint this cable would deal with radio and television. The 59 refers to the impedance of the cable, which tells you how the cable carries signals. RG59 cable, in particular, has 75 Ohms Impedance. We can see that the cable structure consists of several components. In the middle there is a copper wire, that is important part because it carry the signal. The center wire is surrounded by a special material known as a dielectric insulator. On the outside, there's an armored case to shield the signal from interference and noise. Last but not least, an outer additional layer is protecting the whole cable and making sure everything is protected.
At this point, you may be asking yourself if RG59 Cable is right for you or if you would be better off with a different type of cable entirely. The only factor that really determines this is the use case for which you intend to use the cable. So if you have to send video signals over large distances, RG59 Cable is the way to go! It's great at maintaining a strong, clear signal even at long ranges. But in case you are sending digital signals, like what can be used for HDMI or Ethernet cables, you would need to consider other types of cables that are designed for those digital signals. They transfer digital data better than RG59 Cable.
The first step of the cable installation is stripping the outer and metallic shielding from the cable. You want to leave the copper center wire with about 1/4 inch of exposure. This is a significant step in connecting the BNC connector to the cable. Once the center wire is exposed you can simply take the BNC connector and plug it onto the end of the cable. This is achieved by crimping the connector on to the center wire. It needs to be a secure connection so signal can pass through the wire without disruptions.
As with all brands of technology, RG59 Cable has both pros and cons. RG59 cable offers excellent range, sending a quality video signal over long distances without degrading. In other words, you can have clear and strong video signals even across a considerable distance between the devices. Because RG59 Cable is so affordable, you can never let it break the bank. And this is usually much lower than others; hence, it is widely used by many.
RG59 Cable is used by most of the people for video signal transmission in homes as well as in businesses. In home environments, it is commonly used to hook up cable TV boxes to televisions. With this, you can also view your best movies and series in high quality. RG59 Cable is commonly used for security cameras and closed-circuit television (CCTV) applications in commercial settings. This allows businesses to monitor their property and remain secure.
