As the name implies, flexible coaxial cable can move and flex as needed to suit the configuration and geometry of the application. A typical design for 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.

When there is a need to increase flexibility, the metal core conductor may be switched to a stranded design from a solid wire, and a polyethylene (PE) dielectric foam may be substituted for the more rigid dielectric material.

Flexible coaxial cable is the most common type of coaxial cable, familiar to anyone who has seen it in use for the connection of home video equipment and televisions.
