Coaxial Cable Types

 RG58

This cable generally acts as a generic carrier for low-power signals and RF connections.


 RG8

Designed for carrying radio transmission signals. This cable is unable to carry pure video signals due to the design. 

 RG213

Used in military and commercial applications and used within heat sensitive environments. Some of the applications may be used in radio communications, high-performance electrical, data transmissions, broadcast and computer applications.


 RG59

Used primarily for cable TV connections and are commonly seen in order home and commercial installations. The cable has a thin diameter. Generally recommended for low bandwidth and low-frequency applications, such as analog video and CCTV installations.


 RG6

This cable is a heavier gauge with insulation and shielding tuned for high-bandwidth, high-frequency applications such as the internet, cable TV, satellite TV signals. 

 RG11

Designed for long runs and are generally not used for any in-house cases. Generally, this is also twice as thick as a standard coax cable. 



 M17 & RG Coaxial Cable

M17 and MIL-C-17 Coaxial Cable is part of Allied Wire and Cable’s extensive stock of Coaxial Cable. This military grade Coaxial Cables are designed for the transmission of high-frequency signals with a minimum of loss.M17/RG Cables meet all MIL-C-17 requirements and provide good shielding effectiveness. They are low PIM, use standard connectors, and are readily available through distribution.

 RF coaxial cable

RF coax is defined by three elements consisting of a center conductor, an outer conductor, and an insulating spacer between the two conductors. Coaxial cables use a center conductor to transmit electrical signals, generally comprised of single solid copper wire.
RF coaxial cables used to carry radio frequency signals. They’re the standard input cable on TVs and feature a single pin that plugs into the RF input on a device.

 Semi-Rigid Coaxial Cable

Semi-rigid coaxial cable makes use of a solid copper outer sheath with a dielectric of PTFE. The copper sheath generally provides superior shielding effectiveness and dielectric properties. Semi-rigid coaxial cables offer better dielectric properties for enhanced performance at high frequencies. While offering higher shielding performance, this coax is also less flexible and therefore requires fixturing to achieve complex routing bends.

 Semi-Flexible Coaxial Cable

Semi-flexible coaxial cable is a corrugated cable with LowLoss property which is mostly used in the transmission of transmission power to the antennas. Due to the corrugated copper sheath, the cable is recommended only for fixed installation and not for continuous movement. 

A typical design for semi-flexible coaxial cable utilizes a metal inner conductor surrounded by a flexible polymer that functions as the dielectric, with an outer jacket for protection from the environment. This is surprising with a semi-flexible coaxial cable with technically first-class values and low losses.

 TV Coaxial Cable

You can use the TV coaxial cables to connect TVs, satellite dishes and VCRs, and current RF aerials. The coax cables come either as male to male connectors or male to female connectors. You should check out the type of connections your TV and cable boxes have to decide which one you need.

Generally, TV coaxial cables will have an impedance of 75-ohm for better signal transmission. The connectors are gold plated or silver plated in a bid to improve the quality of transmission. The length of the cables is usually short and you the regular TV coaxial cables are 10 meters long.

 What is The Coaxial Cable

A coaxial cable has inner conductors surrounded by several insulating layers. A conducting shield and jacket are then wrapped around the insulation layers to prevent signal interference such as EMI. 
Coaxial cable is commonly used by cable operators, telephone companies, and internet providers around the world to convey data, video, and voice communications to customers. It has also been used extensively within homes.

 What is an Ohm?

An Ohm is the SI unit of electrical resistance that identifies the flow of electrical energy throughout the cable. An Ohm defined as electrical resistance between two points of a conductor in the International Systems of Units (SI). The smaller the Ohm, the better the performance of the coaxial cable. 

 50 Ohm

This coaxial cable can be seen running over 100 feet with commercially installed cables and up to 100,000 square feet in area. 50 Ohm cables are primarily used for high power handling capacity such as routers, radio/TV transmitters, Wi-Fi, ethernet networks, etc. 




 60 Ohm

Europe chose 60 ohms for radio applications around the 1950s. It was used in both transmitting applications and antenna networks. The use of this cable has been pretty much phased out, and nowadays the RF system in Europe uses either 50 ohms or 75 ohms cable depending on the application.

 75 Ohm

These are the standard coax cables that are found within homes and commercial properties. 75 Ohm cables are primarily used for AV signals and can transmit signals up to 50 ft with any installation. This cable can be commonly used for High Def TV signals, Satellite and Cable boxes and police scanners. 75 ohm also offers low attenuation and capacitance acceptance for this digital audio, A/V and data signals. 


 93 Ohm

This is not much used nowadays. 93 ohms was once used for short runs such as the connection between computers and their monitors because of low capacitance per foot which would reduce the loading on circuits and allow longer cable runs. Besides, this was used in some digital communication systems (IBM 3270 terminal networks) and some early LAN systems.


 Different Types of Coaxial Cable

Coaxial cables differ in design depending on their end-use. Shorter cables often appear in household applications such as AV systems or personal Ethernet connections, while longer cables can connect entire radio and television networks or long-distance phones. Micro/mini cables are also frequently used in various consumer, military, aerospace, and medical devices.
