The type of cable it is, who manufactured it, rating, and more. The numbers and letters printed on the cable jacket tell you everything you need to know. Generally, a higher RG numbers means a thinner central conductor, and vice versa. The RG number refers to the cable's diameter. RG, short for Radio Guide, is the original military specification for coaxial cables. Here are the most common coax cable types: RG Coax Cables Your application will determine which one has the best characteristics. They fall within two categories, RG and LMR type. There are many different types of cables to choose from. Each type of coax cable works best with specific applications. Coaxial cables vary in size, material, and shielding. While all coaxial cables are used to transmit signals, they are not all the same. Coax cables carry radio frequency signals. RF (Radio Frequency) waves are generated when an alternating current goes through a conductive material. Ham radios can be set up in the middle of nowhere and do not require internet or cell phone technology. Coaxial cable connected to the antenna provides a stronger signal. Ham radio is a means for people to communicate over airwaves. You can then wire your devices to the router or connect via WiFi for speedy internet access. Your router or cable modem connects to a coax or ethernet outlet to receive the signal. The copper-based cable is piped into your house from the cable service provider. Cable Internet (Copper-Based)Ĭable internet uses coax cable to provide your home with internet. With this technology, you can boost your weak outside cell signal and enjoy stronger signal inside your home, office, or vehicle.

We have a full guide on how a signal booster works for more information. It also bypasses signal blocking material. Coaxial cables are used to connect the three components. These devices use an outdoor antenna, an amplifier, and an indoor antenna.
Wilson Amplifiers is the leading provider of cell phone boosters. They’re also used to connect your television or digital converter box to a personal antenna. If you have cable television, coaxial cable is used to carry video and data from the cable company to your TV.

They’re necessary for applications requiring radio frequency transmissions, such as: Cable TV What are the Uses and Applications of Coaxial CablesĬoaxial cable is used by cable operators, telephone companies, and internet providers. Depending on your application, the signal is then converted into images, audio, WiFi, or amplified cell reception. It also prevents the two signals from coming in contact and canceling each other.Īll components are further insulated and protected from damage by the outer jacket.Īs a result, RF signals can be carried over long distances with little interference or loss. The dielectric insulator makes that happen. Thus, coax can be placed near other electronic equipment without any issues.įor optimal performance, the distance between the core and shield must be consistent throughout. The metal shield also helps protect the signal from electromagnetic interference. This allows the signal to remain intact and not bleed out like it would without the shield. Both components receive a current simultaneously, generating a magnetic field. To ensure a quality signal travels the length of the cable a metal shield is needed. How Do Coaxial Cables Work?Ĭoaxial cables transmit signals through the center wire. Outdoor-rated cables need extra insulation and special jackets to protect the wires from sun and moisture. Its rating (more on this later) lets you know where the cable can be installed. The final layer is a jacket that protects the whole configuration. Some coaxial cables are constructed with multiple shields for extra protection. It cancels outside electromagnetic interference. The metal shield, made of woven copper, aluminum, or other metals, wraps around the insulator. It keeps a constant distance between the center conductor and the next layer. A dielectric insulator, often made of plastic, surrounds the wire. For Commercial What Does A Coaxial Cable Look Like?īefore we get into how coax cables work, you need to know how they’re constructed.Īs you can see from the above image, there are four main parts to a coax cable:Īt the core, coaxial cables consist of a single copper or copper-coated steel wire.
