Short coaxial cables are commonly used to connect home video equipment, in [[amateur radio|ham radio]] setups, and in [[Nuclear Instrumentation Module]]s. While formerly common for implementing [[computer network]]s, in particular [[Ethernet]] ("thick" [[10BASE5]] and "thin" [[10BASE2]]), [[twisted pair]] cables have replaced them in most applications except in the consumer [[cable modem]] market for broadband Internet access.

Long distance coaxial cable was used in the 20th century to connect [[radio network]]s, [[television network]]s, and [[L-carrier|long-distance telephone]] networks though this has largely been superseded by later methods ([[fibre optics]], [[T-carrier|T1]]/[[E-carrier|E1]], [[satellite]]).

Shorter coaxials still carry [[cable television]] signals to the majority of television receivers, and this purpose consumes the majority of coaxial cable production. In 1980s and early 1990s coaxial cable was also used in [[computer networking]], most prominently in [[Ethernet]] networks, where it was later in late 1990s to early 2000s replaced by [[Unshielded twisted pair|UTP]] cables in North America and [[Shielded twisted pair|STP]] cables in Western Europe, both with 8P8C modular connectors.

Micro coaxial cables are used in a range of consumer devices, military equipment, and also in ultrasound scanning equipment.

The most common impedances that are widely used are 50 or 52 ohms and 75 ohms, although other impedances are available for specific applications. The 50 / 52 ohm cables are widely used for industrial and commercial [[two-way radio]] frequency applications (including radio, and telecommunications), although 75 ohms is commonly used for broadcast television and radio.

Coaxial cable is often used to carry signals from an [[antenna (radio)|antenna]] to a receiver. In many cases, the same cable carries power toward the antenna, to power a [[low-noise amplifier|preamplifier]]. In some cases, a single cable carries unidirectional power and bidirectional data/signals, as in [[DiSEqC]].
