Coaxial Cable

Coaxial cable (or coax) is an electrical cable which carriers radio frequency (RF) signals from one device to another. RF cable has been around since the early 20th century and can be found in many applications, for example, connecting a satellite dish to a receiver unit.

There are many variants of coaxial cable and they vary by gauge and impedance - gauge is the cable’s thickness and is measured by the radio guide measurement or RG number. The higher the RG number, the thinner the central conductor is. Coaxial cables are available in a variety of colours including black, brown, yellow and white.

Coaxial cables are a popular choice due to their shielded design which allows the centre conductor to transmit signals quickly while being protected from damage and EMI. Inexpensive, durable and easy to install with up to 80 times more transmission capacity than twisted pair cables. Coaxial cables, with 75 Ohm impedance, are typically used for video signals, while 50 Ohm versions are more suited for wireless communications.
