=== Paired conductors ===
Several types of transmission line exist, and any of them can be used to construct distributed element circuits. The oldest (and still most widely used) is a pair of conductors; its most common form is [[twisted pair]], used for telephone lines and Internet connections. It is not often used for distributed element circuits because the frequencies used are lower than the point where distributed-element designs become advantageous. However, designers frequently begin with a lumped-element design and convert it to an open-wire distributed element design. Open wire is a pair of parallel uninsulated conductors used, for instance, for [[telephone line]]s on [[telegraph pole]]s. The designer does not usually intend to implement the circuit in this form; it is an intermediate step in the design process. Distributed-element designs with conductor pairs are limited to a few specialised uses, such as [[Lecher line]]s and the [[twin-lead]] used for [[antenna (radio)|antenna]] [[feed line]]s.<ref>{{multiref|Hura &
