Coaxial Cable Connector

Coaxial Cables, or RF cables, are best known for carrying the signal we use to watch TV. Most of us recognize them by their plastic covering (usually black or white), their metal heads (which are made to screw on to cable output and input jacks), and the thin, metal connector that protrudes from its middle. Coxial cables were once easily the dominant way to transmit a video signal to a television, but the limitations of its signal quality have changed that equation. However, Coaxial cables are still used very frequently in home TV and internet connections usually to transmit a signal that is converted by another device, like a cable box or modem.

Coaxial connectors are round, hollow and able to be screwed onto the important part is the hollow hole in the middle, which allows a coaxial cable’s center core (which made of metal, usually copper or silver) to be inserted into it. The core of the coaxial cable is the part that carries the signal. In an output like a wall jack, the center core is inserted into is hollow area, and the metal head of the cable is screwed onto the connector. The connector is carrying the signal, and sends it to the cord. When the other end of the cable is screwed onto your device’s input, the signal is sent from one end of the cable to the other.

Coaxial cables have the significant advantage of being able to transmit signals for extremely long distances without losing signal strength. In many cables, like a USB cable, the signal will deteriorate at some point between 10 and 30 feet, depending on the cable quality and the connection type. However, the RF radio signal that a coaxial carries has to be transmitted for a very long distance to reach most buildings. This is also true of the generic cables consumers buy, and the highest quality coaxial cables can transmit their signals for up to almost a mile before showing significant signal degradation.

The coaxial cable used for TV signals is called an F cable, and it is one of the few ways a coaxial cable is still used to transmit its signal directly. In most of the applications it is used for today, a coaxial cable’s signal is sent through a device that interprets or converts it in some way. For example, in internet connections that are transmitted through high-speed coaxial connectors (called RG-60/U coaxial cables), the signal is actually connected to a modem, which then connects to computers through a router or internet connection.

Even in most televisions, coaxial cables are being phased out in favor of digital signals. In this case, the coaxial cable is connected to a set top box. This then transmits the signal to a TV through composite, component or HDMI cables in most cases. This is being done because the RF radio waves sent through a coaxial connection are not capable of carrying a signal that is comparable with any of the previously mentioned connections. In the case of the newer high speed coaxial cables, the signal isn’t recognized by most TV’s.

Because of their ability to transmit signals over extremely long distances, coaxial cables will continue to be used in most households for a very long time. Beyond that fact, coaxial connections also have the advantage of being built into most homes and apartments, which means that it is the most natural connection to have. Currently, there isn’t a preferable method to connect homes to data signals, but even if one were to be developed, it would take very long time for coaxial cables to be replaced. It is possible to find coaxial cables at any store that sells electronic equipment, where they usually cost between $5 and $30 USD, depending on the length and quality of the cable.
